Notes on Batteries

Do not charge a dry battery. 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 accidentally come into contact with metallic objects. If you are not going to use the unit for a long time, remove the batteries to avoid damage from battery leakage or corrosion.

AC power adaptor (supplied)
Sending RF signals from the transmitter Notes

Use only the supplied AC power adaptor. Do not use any other AC power adaptor. The transmitter starts sending RF signals automatically when it detects an audio signal from the connected equipment. If it does not detect an audio signal for more than about 4 minutes, the transmitter will stop sending RF signals, and the POWER/CHG indicator will turn off. When the transmitter receives an audio signal again, it starts sending the RF signals, and the POWER/CHG indicator will light up green again. If the audio signal is very weak, the transmitter does not send RF signals. If the transmitter is connected to a headphone jack, make sure the volume of the equipment connected is set to 5 - 6 or higher. 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.

Note About the charging method of the system
This system employs a contactless charge method that requires no terminals by the electromagnetic induction. The rechargeable nickel-metal hydride battery should be replaced with new one when they last only half the expected time after a proper recharging. The rechargeable battery type 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.
Connecting cord (1) (phono plugs y stereo miniplug), 1 m
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.

Distortion

, If the transmitter is connected to the headphones jack, turn down the volume on the connected audio/video equipment. , Change the radio frequency with the CHANNEL selector switch on the transmitter, then set to the same radio frequency with the TUNING selector (or TUNING button) on the right housing of the headphones. , The headphones POWER indicator light turns off, dims, flashes, or sound becomes distorted or noisy. Charge the rechargeable battery if it is weak, or replace alkaline batteries with new ones. If the POWER indicator is still off after charging the battery, take the headphones to a Sony dealer.
