Additional Information
Cause and remedy
, No power supplied to the processor.
• Connect the processor to a power source.
, No playback sound from the connected external digital unit at the optical
input jack.
• Check that the external unit is playing back.
, Connect the analogue out to the LINE IN jacks, and select the sound on the
connected component.
, The headphones cannot receive the signal from the processor.
• Move within the RF signal transmission area.
• Check the connection of the processor, AC power adaptor, and AC outlet.
• Check if there is any wireless apparatus using 2.4 GHz frequency, or a
microwave oven around the processor and headphones.
• Change the position of the processor.
, There is no audio signal input for about 5 minutes and RF signals are not
transmitted.
• Input the audio signal to the processor and press TUNE/ID SET on the
headphones once.
, Additional headphones are being charged.
• Remove the additional headphones from the processor.
, If the wireless LAN uses the 2.4 GHz frequency, change the channel. If
possible, use 5 GHz.
, Keep the processor more than 2 m away from other devices (wireless LAN,
cordless phone, etc.) using the 2.4 GHz frequency.
, While any other devices (wireless LAN, cordless phone, etc.) using the
2.4 GHz frequency are operating, press TUNE/ID SET on the processor once,
and then press TUNE/ID SET on the headphones once.
The processor detects the optimum frequency for transmitting and switches to
it automatically.
If the problem is not solved, repeat the above procedure.
