Polarity of the plug
When the transmitter is placed on or near a TV, it may pick up a
noise. In such a case, place the transmitter away from the TV.
If the connected equipment has the AVLS (Automatic Volume
Limiter System) function, be sure to turn the function off when
using the transmitter. Otherwise, you will have to turn up the
volume of the headphones, and that may cause noise.
Do not lift the transmitter by the aerial. The aerial cover may
become detached. If it becomes detached, attach it back where it
was before.

Sending RF signals from the transmitter
The transmitter starts sending RF signals automatically
when it detects an audio signal from the connected
equipment.
If the transmitter does not detect an audio signal for more
than about 4 minutes, it will stop sending RF signals, and
the POWER indicator will blink for 1 minute, and then turn
off.
When the transmitter receives an audio signal again, it starts
sending the RF signals, and the POWER indicator will light
up green again.
You may not hear the beginning of the sound from the
headphones until the transmitter starts sending the RF
signals after detecting an audio signal.
RF signal transmission may stop when an extremely low
sound is input for about 4 minutes. If this happens, raise
the volume of the connected AV component within the
range where the sound is not distorted, and lower the
volume of the headphones.
Notes
If hiss is heard, move closer to the transmitter.
You may hear some noise when you disconnect the AC power
adaptor from the transmitter before turn off the headphones.
The effective areas of the
transmitter
The optimum distance is up to approximately 100 m without
the system picking up some interference. However, the
distance may vary depending on the surroundings and
environment. If the system picks up some noise within the
above mentioned distance, reduce the distance between the
transmitter unit and the headphones, or select another
channel.
Notes
When you use the headphones inside the effective areas of the
transmitter, the transmitter can be placed in any direction from the
listener.
Even within the signal reception area, there are some spots (dead
spots) where the RF signal cannot be received. This characteristics
is inherent to RF signals, and does not indicate malfunction. By
slightly moving the transmitter, location of the dead spot can be
changed.
Replacing the earpads
The earpads are replaceable. If the earpads become dirty or
worn out, replace them as illustrated below.
The earpad is not commercially available. You can order
replacements from the store where you purchased this
system, or at your nearest 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.
Hang the edge of the earpad on one side of the driver
unit’s groove edge, then turn the edge of earpad around
the driver unit as illustrated below.
When the earpad is securely inserted into the groove,
adjust the earpad to the vertical position.
Additional information
Precautions
If the transmitter is not to be used for a long period of
time, disconnect the AC power adaptor from the AC
outlet by holding the plug. Do not pull on the cord.
