RF signal transmission from the transmitter automatically stops when an audio signal is not input for 5 minutes. The RF signals are automatically transmitted when an audio signal is input again. RF signal transmission may stop when an extremely low sound is input for about 5 minutes. If this happens, raise the volume of the connected audio or video component and lower the volume of the headphones. If signal noise is output from a component connected to the LINE IN jacks, RF signal transmission may not stop.
Tip
If RF signal transmission from the transmitter stops when an audio signal is not input for 5 minutes, the RF signals are automatically transmitted when an audio signal is input again. The RF indicator blinks and the transmitter detects the optimum frequency for transmission. If the transmission frequency changes after the RF indicator lights up and no sound is heard, press TUNE/ID SET on the headphones once and tune to the new frequency.
Note
The headphones should be used within the RF signal transmission area (see “RF signal transmission area” (page 19)).
