About sending RF signals

The transmitter starts sending RF signals automatically

when it detects an audio signal from the connected

component.

Notes

 If hiss is heard, move closer to the transmitter.

 You may hear some noise when you disconnect the

AC adaptor from the transmitter before turn off the

headphones.

If no signal or low signal is input

for about 4 minutes

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 A/V component

within the range where the sound is not distorted, and

lower the volume of the headphones.

Tips for charging

Charge the headphones first

The supplied rechargeable nickel-metal hydride battery is

not charged from the first time you use them. Charge

them before use.

If the transmitter’s POWER indicator

does not light up red

Check if the switch on the left housing of the headphones

is set to OFF. If the switch is set to ON, the POWER

indicator does not light up.

Tips for better reception

Receiving performance

This system utilizes very high frequency signals in the 800

MHz band so the receiving performance may deteriorate

due to the surroundings. The following examples illustrate

conditions that may reduce the reception range or cause

interference.

 Inside a building with walls containing steel beams.

 An area with many steel file cabinets, etc.

 An area with many electrical appliances capable of

generating electromagnetic fields.

 The transmitter is placed on a metal instrument.

 An area facing a roadway.

 Noise or interfering signals exist in the surroundings

due to radio transceivers in trucks, etc.

 Noise or interfering signals exist in the surroundings

owing to wireless communication systems installed

along roadways.

Effective area 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 and the headphones, or select another

channel.

 When you use the headphones inside the effective area

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 characteristic 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

earpads are 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.
