B MDR-RF920RK

Tune the headphones into the frequency of the transmitter with the TUNE control until you can hear the audio signal loud and clear. Sending RF signals from the Transmitter The transmitter starts sending the RF signals automatically, when it detects audio signals from the equipment connected. If it does not detect an audio signal for more than approximately 10 minutes, the transmitter will stop sending RF signals, and the power indicator turns off. When the transmitter receives an audio signal again, it starts sending the RF signals, and the power indicator will light in red 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 If the transmitter is connected to the headphones jack of the source equipment, set the volume of that equipment as high as possible without distorting the audio signal. The headphones automatically turn off when they are taken off – Auto power on/off function TUN

Do not pull up the self-adjusting band when not in use, as this will consume the battery power. TUNE control VOL control Follow steps 3 and 5 above until the receiving performance becomes better.

• If hiss is hear, move closer to the transmitter.
• You may hear some noise when you disconnect the AC power adaptor from the transmitter before taking off the headphones. After listening to a program Take the headphones off and rest them away on the transmitter, and recharge them. Note Do not hang the headphones by the self adjusting band, otherwise, the self adjusting band will be pulled up and the headphones will be switched on. 10GB The effective areas of the transmitter The optimum distance is up to approximately 46 m (150 feet ) without the system picking up some interference. However, the distance may vary according to the surroundings and environment. If the system picks up some noise while using it within the above mentioned distance, reduce the distance between the transmitter unit and the headphones, or select the other channel. Replacing the ear pads The ear pads are replaceable. If the ear pads become dirty or worn out, replace them as illustrated below. The ear pad is 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 ear pad by pulling it out of the groove on the housing. Notes
• When you use the headphones inside the effective areas 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 spot) where the RF signal can not be received. This is a characteristic inherent to RF signals, and does not indicate malfunction. By slightly moving the transmitter, location of the dead spot can be changed. 2 Place the new ear pad on the driver unit and insert the edge of the pad into the groove as illustrated. Make sure that the entire edge of the ear pad is securely inserted into the groove. 11GB N Additional information Troubleshooting Precautions
• When the transmitter is not to be used for a long period of time, disconnect the AC power adaptor from the AC outlet holding the plug. Do not pull on the cord.
