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 it on a metallic table.

If no signal or low signal is input for about 4 minutes

When no signal is input for about 4 minutes, the transmitter turns off automatically*. The POWER indicator of the transmitter blinks for 4 minutes, then turns off. The transmitter restarts after receiving an audio signal again. The transmitter may also turn off if the low signal is input for about 4 minutes. 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.

If signal noise is output from the connected A/V component, the transmitter may not turn off, even when no audio signal is input.

Noise Reduction process

The transmitter compresses the audio signal and converts it to an RF signal. The headphones convert the received RF signal to an audio signal and decompress it. This process reduces noise picked up during transmission.

The transmitter compresses the audio signal dynamic range, then converts it to RF signal.
Noise may occur due to long-distance transmission, etc.
The headphones convert the RF signal to an audio signal.
Noise may occur during conversion.
Decompression of the audio signals’ dynamic range reduces the noise level and improves the S/N (signal-to-noise) ratio.

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 the 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 the CHARGE/RED indicator does not light up in 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.

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.

The 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, the 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.

Remove the old earpad by pulling it out of the groove on the housing.
Fit the new earpad in the groove of the housing. Make sure the earpad is set to the vertical position.
