1. Description of device
1.1 Proper use
This baby monitor Eco Control Audio 500
allows you to listen in to your baby or small
child in the nursery. It can also be used for
sound-only monitoring of the elderly.
This device is intended only for dry
environments. It is not suitable for use in
wetrooms or outdoors in wet weather.
This device is intended for use in private
households. It is not intended for
commercial use.
This device is intended as a supplementary
aid. It is in no way a substitute for the
physical presence and attention of parents,
babysitters or carers.
1.2 Description of function
The baby unit 1 is set up in the room that is
to be monitored. It registers the sounds in
the room and sends it wirelessly to the
parent unit 8.
The parent unit 8 has a built-in rechargeable
battery so that you can always set it up
where you can see it. The battery is
recharged using the supplied mains
adapter.
The limiting distance between baby and
parent unit is about 40 m indoors and up to
250 m outdoors (in open country). The
babyphone’s reception will vary depending
on its surroundings. Thick walls or metal can
reduce the range.
The babyphone has an Eco-Mode, in which
the transmitter (baby unit) automatically
switches to standby as soon as your baby is
sleeping peacefully. Depending on the
sensitivity setting, it will not switch back on
until your baby begins making a noise or
starts to cry.
If you want to be sure of hearing every
single sound from the nursery you can use
the VOX 17 button to set the transmission
sensitivity to its maximum (=level 5). On this
setting the baby unit is continually switched
on (see "6.3 Using the VOX function to
adjust the transmission sensitivity" on
page 28).
If you do not want to hear any sounds at all
you can use the Vol - 11 button to set the
volume to mute. In this case only the LED
display 16 will show you if your baby is
making noise.
Activating Eco-Mode minimises the high-
frequency radiation in the childrens room. In
this mode the baby unit merely sends a brief
signal to the parent unit every 30 seconds to
test the connection. If the parent unit is out
of range, the parents will be alerted by a
beep.
You will find more information about Eco-
Mode in "4.5Eco-Mode" on page 26 and in
"6.3Using the VOX function to adjust the
transmission sensitivity" on page 28.

following:
Avoid short circuits.
The battery poles should never be
allowed to come into contact with any
metal objects, as this could cause a short
circuit. A short circuit can cause the
battery to overheat, in which case it
could leak electrolyte and possibly cause
an explosion or fire.
If electrolyte does leak out, avoid any
contact with skin, eyes and mucous
membranes in order to prevent injuries. In
the event of any contact with the
electrolyte, rinse the affected areas with
plenty of clean fresh water and
immediately seek medical attention.
The built-in battery may be replaced only
by a genuine replacement battery. If the
battery is defective, please contact one
of our service addresses (see "Contact
addresses NUK“ on page115).
To avoid the risk of explosion, normal
batteries should not be recharged,
heated up or disposed of by incineration.
Never try to open the battery, bend the
contacts or pull them off. Do not throw
the battery onto the floor or knock nails
into it.
Damaging the battery could cause an
internal short circuit, in which case it
could leak electrolyte and possibly cause
an explosion or fire.
Use only the supplied mains adapter to
charge the battery.
Using the wrong mains adapter could
overcharge it, causing it to overheat and
explode.
LiPo batteries may be charged or stored
only on heatproof, non-combustible
surfaces.
LiPo batteries may be charged only under
supervision so that you can intervene in
good time in the event of a failure.

3. Slide the battery cover 9 back onto the
parent unit 8.
4. Insert the small plug of the mains adapter
into the mains adapter socket 19 of the
parent unit.
5. Insert the plug into a power socket that
matches the rating given in the technical
data (see "9. Technical data" on
page 31).
6. Initially, charge the parent unit
continuously for 10 hours to activate the
full battery capacity.
Subsequently the battery will take only
about 5 hours to charge. It can also be
charged while the unit is in operation.
The POWER 15 LED indicates that
charging is in progress. If it:
flashes green: the battery is currently
being charged;
lights up green: the battery is fully
charged;
lights up red and beeps at one minute
intervals: low battery warning. Within
about 15 20 minutes the parent unit
will switch off automatically.
4.2 Connecting the baby unit
Note: Don’t install the baby unit 1 until the
battery of the parent unit 8 is fully charged.
1. Put the baby unit 1 somewhere in the
nursery where your baby will not be able
to reach it.
An optimal distance between baby and
the baby unit is from 1 to 2 m.
2. Insert the mains adapter plug into the
socket 3 of the baby unit 1.
3. Insert the plug into a power socket that
matches the rating given in the technical
data (see "9. Technical data" on
page 31).
4.3 Connecting baby unit and
parent unit
1. Use the On/Off button 5 to switch the
baby unit 1 on. Keep the button pressed
for a moment until the Power LED 6 lights
up.
2. Use the On/Off button 14 to switch the
parent unit 8 on. Keep the button pressed
for a moment until the LED 15 lights up a
steady green.
The connection will be set up
automatically. While this is being done
the connection indicator 13 will light up
red.
As soon as the connection has been
established, the connection indicator on
the parent unit 13 and the VOX LED on
the baby unit 7 will light up green.
If the connection indicator 13 begins to
flash green, this means that there is a
connection between the parent unit and
the baby unit, but your baby is currently
asleep and therefore the device has
automatically activated Eco-Mode to
reduce the high-frequency radiation in
the children’s room and save energy.
In the event that the connection between
the parent unit and the baby unit breaks
down, the devices will automatically attempt
to establish a new one.
If a new connection is not established within
30 seconds, the parent unit 8 will emit a
regular beep and the connection
indicator 13 will light up red. You may need
to move the parent unit to a different
location before a new connection can be
established.
3. First go and check on baby to make sure
everything is OK.
4. Then try to set up a new connection by
moving about.
The connection will be automatically re-
established as soon as you are within
range.
26
As soon as the connection has been set
up the connection indicator 13 will again
light up green.
4.4 Power supply
The power supply for the baby unit 1
works only via the mains adapter.
The parent unit 8 can be operated with
no mains connection using the battery.
The state of the battery is indicated by the
POWER 15 LED. If it:
lights up green: the device is switched
on and the battery is fully charged;
flashes green: the battery is currently
being charged;
lights up red and beeps at one minute
intervals: low battery warning. Within
about 15 20 minutes the parent unit
will switch off automatically.
During these 15 minutes you can still
activate and deactivate any functions
you wish. Please be aware that using
e.g. the Talk-Back function and/or
maximising the volume control will
increase the unit’s power consumption
and therefore reduce the remaining
time you have available. You should
connect the mains adapter to your
mains supply as soon as the
POWER 15 LED begins to flash red.
The parent unit can be connected to the
mains via the mains adapter and receive
power from there, while at the same time
recharging the battery. If the parent unit is
switched on, recharging the battery will
take somewhat longer. While the battery
is charging, the LED 15 flashes green.
Notes:
With a fully charged battery you can
operate the parent unit for up to
18 hours. The exact time will depend
on how the unit is used (whether the
parent unit frequently switches on,
whether the two-way speaking function
is much used, how high the volume is
set, etc.).
Charging an empty battery takes about
5 hours.
4.5 Eco-Mode
Description of function
This babyphone has an Eco-Mode setting,
which not only saves electric power but also
minimises the high-frequency radiation in
the nursery.
At VOX levels 1, 2, 3 and 4, (see "6.3 Using
the VOX function to adjust the transmission
sensitivity" on page 28) Eco-Mode is
activated automatically about 10 seconds
after your baby goes to sleep and no longer
makes any noise.
You can see when this happens because the
connection indicator 13 will begin to flash
green. In Eco-Mode, not only the baby unit
is automatically set to standby, but also the
parent unit.
While Eco-Mode is activated, any functions
that might wake the baby are automatically
deactivated. For example, you cannot use
the Talk-Back function, but even in Eco-
Mode you are always connected to your
baby and always know if you are still within
range.
This babyphone has a range checker that
also works in Eco-Mode. If you are out of
range, you will automatically receive a
warning even if Eco-Mode is activated,
because even in standby mode, the baby
unit sends a signal to the parent unit every
30 seconds to check the connection.
If the connection indicator 13 lights up
green, there is a functioning connection
between the baby unit and the parent unit. If
the connection indicator 13 flashes green,
Eco-Mode has been activated. If the
connection indicator 13 changes to red, this
means that you are out of range and/or the
two units are no longer communicating.
Note: Check the range of your baby monitor
before using Eco-Mode. Make sure that the
two units are always within range, so that
you can hear your baby.
The device automatically switches to
transmission mode as soon as your baby
27
makes a noise that exceeds your selected
sound threshold (VOX levels 1 - 4). Eco-
Mode is deactivated immediately and the
connection indicator 13 stops flashing.
At VOX level 5 the device transmits
continuously and Eco-Mode is deactivated.
If you want to check that everything is OK
while Eco-Mode is activated (although this
already indicates that your baby is sleeping
peacefully), you can deactivate Eco-Mode
by switching to permanent transmission
mode:
1. press the VOX button 17on the parent
unit 8.
2. Then press the Vol+ button 10 repeatedly
until all 5 LEDs 16 are lit.
5. Operating the baby unit
5.1 Switching the baby unit on
and off
The baby unit 1 will switch on automatically
as soon as you have connected the mains
adapter and plugged it into the power
supply. You can subsequently switch the
baby unit on or off at any time:
To switch the baby unit 1 on or off, press
the On/Off button 5.
5.2 Indicator LEDs
The Power LED 6 lights up green while
the baby unit is switched on.
The VOX LED 7 on the baby unit lights up
green when there is an established
connection between it and the parent
unit.
The VOX LED 7 will not be lit while the
baby unit 1 is switched to Eco-Mode or if
it was not possible to set up a connection
to the parent unit.
6. Operating the parent unit
6.1 Switching the parent unit
on and off
To switch the parent unit 8 on or off, press
and hold the On/Off button 14:
when you hear a beep and the Power
LED 15 lights up, the parent unit is
switched on;
when you hear a beep and the Power
LED 15 goes out, the parent unit is
switched off.
6.2 Indicator LEDs
The connection indicator 13 on the
parent unit 8 shows the state of the
connection to the baby unit 1. It:
lights up green when it has a
connection;
flashes green when the baby unit is in
Eco-Mode and indicates that your
baby is sleeping peacefully;
lights up red if the connection has
broken down or the baby unit is
switched off.
Notes:
If the baby unit 1 is in Eco-Mode and
the parent unit moves out of range, the
connection indicator 13 will light up
red. You will also hear a beep every
30 seconds.
As soon as the parent unit 8 comes
back into range, or the reason for the
breakdown in communications is
eliminated, the connection indicator 13
lights up green again indicating that the
units are able to communicate.
When the units are first switched on,
the connection indicator 13 will initially
be red. The parent unit and baby unit
will set up a connection. As soon as the
connection is set up the display will
turn green.
28
The power supply indicator POWER 15:
lights up green: the device is switched
on and the battery is fully charged;
flashes green: the battery currently
being charged;
lights up red and beeps at one minute
intervals: low battery warning. Within
about 15 20 minutes the parent unit
will switch off automatically. Please be
aware that this interval may be
reduced, depending on how you use
the device (for example, VOX level 5
uses more power than level 1).
The display 16 with the 5 LEDs has three
functions. The LEDs are only visible when
in use.
indicates the noise level in the nursery.
The more LEDs are lit, the louder the
noises;
indicates the different levels when you
are adjusting the volume. The more
LEDs are lit, the louder the sound from
the loudspeaker;
indicates the different levels when you
are adjusting the VOX sensitivity. The
more LEDs are flashing, the sooner the
device will react to sounds. If 5 LEDs
are lit the device will switch to
continuous transmission.
6.3 Using the VOX function to
adjust the transmission
sensitivity
Babies make a lot of different noises. These
can range from loud breathing through
babbling to calling or loud crying. The VOX
function can be set up in such a way that
only loud sounds such as crying or calling
are transmitted while quieter sounds are not
registered.
The VOX function sets up the transmission
sensitivity of the microphone. The higher the
VOX level the more sensitive the device is to
noises.
1. You activate the VOX function by briefly
pressing the VOX button 17.
The LEDs 16 indicate the sensitivity of
the current setting by flashing.
2. You can increase or decrease the
transmission sensitivity by pressing one
of the buttons VOL + 10 or VOL - 11. The
number of flashing LEDs 16 corresponds
to the selected level:
VOX level 1 = extremely low sensitivity,
reacts only if baby screams really
loudly;
VOX level 2 = low sensitivity, reacts if
baby screams loudly;
VOX level 3 = normal sensitivity, reacts
if baby cries normally;
VOX level 4 = high sensitivity, reacts
even to slight sounds;
VOX level 5 = Eco-Mode is switched
off. The unit is set to transmit continu-
ously.
You can set up the volume at which the
parent unit should output the transmitted
sounds using the two buttons VOL + 10 and
VOL - 11 (see "6.4 Adjusting the volume
control" on page 29).
Note: After activating the VOX function, you
have about two seconds to alter the
transmission sensitivity. The device will then
automatically switch back to transmitting
sounds. You can see this has happened
because the LEDs 16 will no longer be
flashing, and the VOL + 10 and VOL - 11
buttons now only modify the volume.
Caution! In continuous transmission mode
at VOX level 5, all sounds are transmitted
continuously. When the baby is sleeping
peacefully, the volume is automatically
reduced to its lowest level after a few
seconds to minimise background noise. As
soon as the child begins to make a noise,
the volume automatically returns to its
previous setting.
29
6.4 Adjusting the volume
control
1. You can use the VOL + 10 and VOL - 11
buttons to set the volume at which you
hear the sounds emitted by the parent unit.
Each time you press one of the buttons you
will hear a beep at the volume that is
currently set up and it will show you with
the accordance of lit LEDs 16. The louder
your chosen setting, the louder any beeps
will be and the more LEDs will light up.
Note: When the VOX function is set to
low sensitivity (see "6.3 Using the VOX
function to adjust the transmission
sensitivity" on page 28), then quiet
sounds will not be transmitted regardless
of the volume setting. This means that
turning up the volume will not enable you
to hear anything more. If you want to hear
more of the sounds from the nursery you
will need to increase the transmission
sensitivity by selecting a higher VOX
level.
6.5 Mute setting
The parent unit can be “MUTED. Sounds
from the nursery will then no longer be
transmitted.
1. Press the VOL - 11 button repeatedly
until you can no longer hear beeping.
No sounds will now be transmitted.
2. The LEDs 16 will continue to indicate the
noise level in the nursery. The more LEDs
are lit the louder are the noises in the
nursery.
3. You can cancel the mute setting by
pressing the VOL + 10 key.
4. If the parent unit is muted and you
activate the Talk-Back function, the
volume will automatically return to the
first level.
6.6 Talk-Back function
You can use the “Talk-Back” function to
speak to your baby.
1. Hold down the TALK 18 button on the
parent unit.
When you hear a beep, this means that
voice connection is established.
2. At the same time, speak into the
microphone 20 on the parent unit.
Your baby can now hear your voice from
the loudspeaker 2 on the baby unit.
3. Release the TALK 18 button in order to
hear the baby’s reaction.
Notes:
If the baby unit 1 is in Eco-Mode, this
function is deactivated so that you do
not inadvertently wake your baby. In
this case, two consecutive beeps will
remind you that the Talk-Back function
is currently not available.
If the volume of the parent unit is set to
“MUTE” (see "6.4 Adjusting the volume
control" on page 29), it will
automatically be increased to level 1 as
soon as you press the TALK 18 button.
7. Cleaning and care
7.1 Cleaning

9. Technical data
9.1 FHSS Technology
The wireless transmissions of this baby
monitor use modern FHSS technology.
Frequency Hopping Spread Spectrum
(FHSS) is a digital frequency spreading
method for wireless data transmissions.
Unlike earlier methods, the whole of the
transmission power is not concentrated on a
single frequency. Instead, the carrier
frequency is changed at random. The
individual data packets transmitted via the
different carrier frequencies are then
reassembled in the receiver.
This method has several advantages over
conventional radio transmission:
It is also much more difficult to intercept
the radio signal, because the listener
does not know how the signal is
distributed among the different
frequencies and how to correctly
reassemble it. For this reason the same
method is used by Bluetooth and by the
military.
Radio transmissions that use this method
are also much less susceptible to
interference. This is because a given
carrier frequency is always used only very
briefly before switching to another. If
there is interference on one frequency it
will affect only small data packets, and
appropriate correction algorithms can
compensate for such errors.
Wireless connection 2.4 GHz FHSS
Transmission frequency 2408 MHz - 2474 MHz, max EIRP 100mW
Number of channels 12 / automatic channel selection
Line of sight range about 250 m
Range within enclosed rooms about 40 m. Successful transmission depends on the environment.
Walls or trees can seriously interfere with reception.
