Notes
When you use the headphones inside the effective a reas of the
transmitt er , the transmitt er can be placed in any direction fro m the
listener .
Even within the signal reception area, there a re some spots (dead
spots) where the RF signal cannot be receiv ed. This characteristics
is inherent t o RF signals, and does not indicate malfunction. By
slightly movin g the transmitter , location of the dead spot can be
changed.
Checking the remaining

Notes
When watching films, be careful not to ra ise the volume too

This e quipm ent is guaran teed for use in the tempera ture rang e
of 5°C to 35°C (41°F to 95°F).
Y ou may hear some n oise when you disconnect the A C power

Note
Not e that batt ery c apacity ma y decrease if the headphones a re turned
on and placed on the tran smitter with the A C power adap tor
disconnected from the transmit ter .
Sending RF signals from the transmitter
The transmit ter starts sending RF signals aut omatically
when it detects an audio signal fro m the connected
equipmen t.
Notes
Any noise you hear thro ugh the headphones ma y vary depending
on the transmit ter position and roo m conditions. I t is
recommended tha t you place the transmit ter in a location that
produces the clear est sound.
If the transmitter is placed on a metallic table, y ou may hear no ise,
or the reception ra nge may decr ease.
Do not place the transmit ter on a metallic table.
If an audio signal is not input for about 5
minutes
RF signal transmission fro m the transmitt er auto matically
stops when an a udio signal is not in put fo r about 5 min utes.
When the transmi tter sto ps, the transmitter ’ s POWER
indicato r blinks in green for 60 seconds a nd then turns off.
The RF signals are a utoma t ically transmitt ed when an audio
signal is inpu t again. RF signal transmissio n may sto p when
an extremely lo w sound is in put fo r about 5 min utes. If this
happens, ra ise the volume o f the connected A V component
within the range wher e the sound is not disto rted, and low er
the volume o f the headphon es.
If signal noise is o utpu t from a com ponent co nnected to the
A UDIO IN jacks, RF signal transmission ma y not sto p.
Noise Reduction process
The transmit ter unit com presses the a udio signal and
con verts it to RF signal. The headpho nes unit con verts t he
received RF signal to an a udio signal and decom presses it.
This process r educes noise pick ed up during transmi ssion.

When cha rging is com plete, there is no n eed to remove the
headphon es from the transmit ter after char ging has
comp leted.
Notes
The transmitter aut omatically turns o ff while charging the battery .
Avo id exposure to tem perature extremes, dir ect sunlight, moistur e,
sand, dust o r mechanical shock.
If the headphones are u sed outside the recommended tem perature
range, the CH G indicator flashes and c harging stops. Cha rge in an
enviro nmental tempera ture of between 5°C and 35°C.
If you haven ’t used the headphones f or a long period of time, the
life of the recha rgeable bat tery may become short. This will
impr ove when you r epeat the charging a nd discharging pr ocess
several times.
When the battery life reduces to half, this may be the end o f battery
lifetime. Fo r how to ch ange bat teries, consult yo ur place of pur chase
or a Sony dealer .
D o not stor e the headphones in h ot places for a lo ng period of time.
When sto ring it for mo re than a year , charge the bat tery once a year
to preven t over discha rge.
D o not touch the co ntact pin of the tran smitter . If a contact pin
becomes dirty , charging may not be possible.
C harging ma y not be comp leted if the transmitter ’ s contact pin and
headphones ’ contact point ar e dusty . Wi pe them with a cotton bud ,
etc.
The sound cuts off
The transmit ter stops tran smitting if no signal is inp ut for 5
minutes.
If you connect the transmitt er to an A V component using the
headphone jac k, raise the volume level o n the connected A V
componen t within the range wher e the sound is not disto rted.
The battery cannot be charged
Check if the CHG indica tor turns on. I f not, pu t the headphones
on the transmit ter correctly so that the CHG indica tor turns o n.

Check that the A C power adap tor is connected to the tran smitter .
Precautions
If the transmi tter is not t o be used for a long period of
time, disconnect the AC po wer adapt or from the A C
outlet by h olding the plug. Do not p ull on the cord.
Do not leave the wir eless stereo headp hone system in a
location sub ject to direct sunlight, heat or mo isture .
Notes on headphones
T o reduce the risk of hearing damage
A void using headph ones at high vo lume. H earing experts
advise against co ntinuo us, loud and exten ded play . If yo u
experience a ringing in your ears, r educe the volume o r
discontin ue use.
Caring for others
Keep the vol ume at a modera te level. This will allow you t o
hear outside soun ds and to be considera te to the people
aroun d you.
If yo u have an y questions or pr oblems concernin g the
system that a re not co vered in this man ual, please consult
your near est Sony dealer .
Be sure to bring the headph ones and the tran smitter to the
Sony dealer when requiring r epair work.
