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.

Approx. charging time Approx. usage time

7 hours

18 hours

1) at 1 kHz, 0.1 mW + 0.1 mW output

2) hours required to fully charge an empty battery

3) Time may vary, depending on the temperature or conditions

of use.

To recharge supplied battery after use

Place the headphones on the transmitter after use. The CHG/RED

indicator lights up red, then charging starts.

When charging is complete, there is no need to remove the

headphones from the transmitter.

Remaining battery

To check the remaining battery charge of the headphones, pull

up the self-adjusting band, and check the POWER indicator. The

battery is still serviceable when the indicator lights up green.

Charge the headphones if the POWER indicator turns off, dims,

flashes, or the sound becomes distorted or noisy.

Notes

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.

Charge in an environmental temperature of between 5 °C and

35 °C (between 41 °F and 95 °F).

When the battery life reduces to half, this may be the end of

battery lifetime. The supplied rechargeable battery BP-HP550-

11 is not commercially available. You can order the battery

from the store where you purchased this system, or at your

nearest Sony dealer.

–

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.

Battery life

Battery Approx. usage time

Sony alkaline battery LR03

(size AAA)

28 hours

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.

Troubleshooting

If you run into any problems using this system, use the following

checklist. Should any problem persist, consult your nearest Sony

dealer.
