uction manual for the Babyfon® BM 400
General
Congratulations!
With your new Babyfon® you have purchased a quality product from Vivanco. Please read the instruction manual carefully to
familiarise yourself with all the possibilities provided by your Babyfon and its correct operation. Babyfon® was developed to transfer
voice signals / sounds made by children. Signal tones, e.g. from breathing or heart tone monitoring equipment, cannot be transferred.
Use of the Babyfon® cannot replace, but only support the personal supervision of a child or person in need of care.
Babyfon® points out that it does not accept any responsibility whatsoever not covered by legal guarantee regulations.
This applies in particular to this Babyfon® being used for medical purposes for which it is not intended.
As a quality product, Babyfon® naturally meets all national and European licence requirements.
N.B.
This Vivanco FM product complies with the European R&TTE Directive for FM systems in non-harmonised frequency ranges. The
sale and operation of these systems is possible in the following countries: D, GB, F, E , I, NL, DK, B, LUX, P, FIN, S.
In non-EU member states the national licence regulations must be observed.
Electro-smog in children’s rooms
Due to the extremely low radiation level of 10mW (maximum), there is no risk to the health of your child due to electro-smog,
according to current knowledge. We nevertheless recommend that you keep a safety distance of 1 metre between your baby and
the Babyfon® transmitter. Never place the device in the child’s cot or playpen.
The functionality of the Babyfon® is not impaired in any way by the safety distance. The original Babyfon® is equipped with a voice
control feature that only allows the device to transmit when your child really makes a noise. Therefore the Babyfon® only transmits
when required and not permanently, preventing superfluous electro-smog.
When using AC adapters you can minimise low-frequency magnetic fields by keeping a distance of at least 1 metre between the
wall socket (230V/50Hz) and the child’s cot. If you wish to minimise electro-smog further in the child’s room it is recommended to
operate the Babyfon® using batteries/battery packs in the transmitter and receiver. This ensures that there will be no risk of electro-
smog from the Babyfon® for your child.
Besides performing its basic function, your Babyfon® BM 400 also has the following features:
• Variable response sensitivity
In order to ensure optimal adaptation to your everyday life / surrounding noise you can determine the switch-on threshold of the
Babyfon®. Depending on your individual requirements, the transmitter can be activated either by slight noises or from a certain
volume level.
• Belt clip / wall mounting
The transmitter and receiver are fitted with a practical belt clip. Using a screw or hook you can also use the belt clip as a practical
wall mounting.
• 40 MHz/ 2 transmission channels
Interference by CB transmitters is impossible due to the 40 MHz frequency range used.
• Pilot signal technology
To prevent interference, the Babyfon® transmitter emits an inaudible, coded signal as soon as it is activated. Only when this signal
is received does the receiver switch itself on, thereby preventing the reception of external radio transmissions. This makes
interference from, for example, other baby monitoring systems almost impossible. Should interference come from an equivalent
model you can also change the pilot signal in the battery compartments of the transmitter and the receiver.
• Acoustic range control
An acoustic signal (beep tone) tells you when the receiver is outside the range of the transmitter. N.B.: When the receiver is switched
on the beep tone sounds for a few seconds. This stops as soon as the transmitter and receiver make contact.
• Variable transmission output
If the transmitter and receiver are used mainly in stationary operation (child’s room > living room) the transmission output of the
Babyfon® can be reduced. This considerably reduces any possible electro-smog (from the transmitter) to the benefit of your child.
Neither the functionality nor reliability of the Babyfon® is reduced! Protect your child from unnecessary electro-smog.
• Battery pack charge function
The transmitter and receiver are equipped with an integrated battery pack charge function for the safe charging of your battery
packs.
