Self-adjusting band
About sending RF signals
The transmitter starts sending RF signals automatically when
it detects an audio signal from the connected component.
Note that;
Noise may occur depending on the transmitter position and
room conditions. It is recommended to place the
transmitter in a location that produces the clearest sound.
If the transmitter is placed on a metallic table, you may hear
noise, or the reception range may decrease. Do not place on
a metallic table.
If low signal or no signal is input for
about 5 minutes
If low signal is input for about 5 minutes, the transmitter turns
off automatically*. If the volume of the connected A/V
component is too low, the transmitter may also turn off. When
low signal is input, the POWER/GREEN indicator of the
transmitter flashes green for 5 minutes, then turns off. In this
case, raise the volume of the connected A/V component
within the range where the sound is not distorted, then lower
the volume of the headphones.
The transmitter may also turn off if no signal is input for about
5 minutes. The POWER/GREEN indicator of the transmitter
flashes green for 5 minutes, then turns off. The transmitter
restarts after receiving an audio signal again.
* If signal noise is output from the connected A/V
component, the transmitter may not turn off, even when no
audio signal is input.

Tips for charging
Charge supplied battery first
The supplied rechargeable nickel-metal hydride battery is not
charged from the first time you use it. Be sure to charge them
before use.
About auto charge function
Placing the headphones on the transmitter automatically turns
them off, then charging starts. This eliminates the need for
turning on/off every time you wear and take off the headphones.
If CHG/RED indicator does not light up
red
Check if the right and left headphones are rested on the
transmitter correctly. Take off the headphones and place them
on the transmitter again so that the headphones’ contact
points meet the transmitter’s contact pins.
Charging may not be completed if the transmitter’s contact
pin and headphones’ contact point are dusty. Wipe them with
a cotton bud, etc.
Charging and usage time
Depending on the remaining battery status, it takes approx. 30
minutes to 7 hours to recharge.

Insert the AC adaptor plug firmly.
Be sure to use the supplied AC adaptor. Using AC adaptors
with different plug polarity or other characteristics can cause
product failure.
Unified
polarity plug
The battery capacity may decrease if the headphones are
turned on and placed on the transmitter with the AC adaptor
disconnected.
The transmitter automatically turns off while charging the
battery.
This system is designed to charge only the supplied
rechargeable battery BP-HP550-11 for safety. Note that other
types of rechargeable battery cannot be charged with this
system.
If dry batteries are installed, they cannot be charged.
Do not attempt to use the supplied rechargeable battery BP-
HP550-11 for other components. It is for use with this system
only.

Using the headphones
with separately-sold dry
batteries
Commercially available (LR03 (size AAA)) dry batteries can also
be used to power the headphones. Install two batteries in the
same manner as described in step 1 of “How to use.”
When dry batteries are installed, the battery charge function is
not activated.

(size AAA)
28 hours
2)
1) at 1 kHz, 0.1 mW + 0.1 mW output
2) Time may vary, depending on the temperature or conditions
of use.
Note
Do not carry a dry battery together with coins or other metallic
objects. It can generate heat if the positive and negative
terminals of the battery are accidentally come into contact with
metallic objects.
Tips for connection
Do not connect to the AUDIO IN 1 and AUDIO IN 2 jacks at the
same time. If you connect two A/V components to both jacks
at the same time, both of the audio signals may result in mixed
output.
When you connect the connecting cable directly to an
earphone jack (monaural mini jack), the audio signal may not
be output through the right channel.
Tips for volume setting
If you connect the transmitter to the headphone jack of the A/
V component, set the volume of the A/V component as high as
possible but not so high that the audio signal becomes
distorted.
When watching videos, be careful not to raise the volume too
high in quiet scenes. You may hurt your ears when a loud
scene is played.
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.
