indicato r lights up red.
Charge the r echargeable ba ttery or install new dr y-cell
batteries if the PO WER indicato r light dims, flashes, or the
sound becomes disto rted or noisy .
Note
The recharg eable nickel-metal h ydride battery should be replaced
with new ones when they last only half the expected time after a

Polarity of the plug
When the transmitter is p laced on or near a TV , it ma y pick up a
noise. In suc h a case, place the transmitter a way from the TV .
If the connected equipmen t has the A VLS (Au tomatic V olume

Before listening
T o reduce the risk of h earing damage, first lo wer the volum e.
1 T urn on the audio/video equipment connected to
the transmitter .
If the transmi tter is connected to the headp hone jack, set
the volume co ntrol o f the audio sour ce equipmen t as
high as possible but no t so high that the audio signal
becomes distorted.
2 Disconnect the CHARGE plug from the
headphones.
The transmit ter’ s POWER indicator ligh ts up green.

3 Select the radio frequency with the CHANNEL
selector switch.
4 T urn on the switch on the left housing of the
headphones.
Check if the power indicat or on the left housin g lights
up red. Place the right h ousing on y our right ear and
the left housing on y our left ear .
There is a tactile dot on the han ger marked to
distinguish the left side.
5 Select the channel to that of the transmitter with
the switch on the right housing of the headphones.
T urn up the volum e to a moderate level with the
V OL UME con trol on the left ho using.
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.
If the transmi tter does not detect an a udio signal for mor e
than about 4 min utes, i t will stop sending RF signals, and
the POWER indica tor will blink for 1 min ute, and then t urn
off.
When the transmi tter receiv es an audio signal again, i t starts
sending the RF signals, and the POWER indica tor will light
up green again.
Y ou may not hea r the beginning of the sound from the
headphon es until the transmit ter starts sending the RF
signals after detecting an audio signal.
RF signal transmission may st op when an extremely low
sound is input f or about 4 minut es. If this happens, raise
the volume of the connected A V component within the
range where the sound is not disto rted, and lower the
volume of the headphones.
Notes
If hiss is heard, mo ve closer to the transmit ter .
Y ou may hear some n oise when you disconnect the A C power
adapto r from the transmit ter before turn o ff the headphones.
The eff ective areas of the
transmitter
The optim um distance is up to a ppr oxima tely 100 m withou t
the system picking u p some interf erence. H owever , the
distance ma y vary dep ending o n the surroundings a nd
enviro nment. I f the system picks u p some noise within the
above men tioned distance, r educe the distance between the
transmit ter unit and the headp hones, or select ano ther
channel.
Notes
When you use the headpho nes inside the effective areas of the
transmitt er , the transmitt er can be placed in any direction fro m the
listener .
Even within the signal reception ar ea, there are some s pots (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.
Replacing the earpads
The earpads are rep laceable. If the earpads become dirty or
worn ou t, replace them as illustra ted below .
The earpad is not commer cially available. Y ou can o rder
replacemen ts from the stor e where you p urchased this
system, or a t your near est Sony dealer .
1 Remove the old earpad by pulling it out of the
groove on the housing .
2 Place the new earpad on the driver unit .
Han g the edge of the earpad on one side o f the driver
unit ’ s groove edge, then t urn the edge of earpad around
the driver unit as illustra ted below .
When the earpad is securely inserted into the groo ve,
adjust the earpad to the vertical position.
