If a beep sound is heard from the headphones
A repeated beep sound is heard if reception conditions deteriorate when the
headphones are outside the signal transmission area, or another wireless apparatus
using 2.4 GHz frequency or microwave oven causes interference. If the beep sound
does not stop after moving closer to the transmitter, let the transmitter detect the
optimum frequency for transmission again following the procedure below.
1
Press TUNE/ID SET on the transmitter once.
The RF indicator blinks and the transmitter detects the
optimum frequency automatically. After detection is
completed, the RF indicator lights up and emission starts.
2
Press TUNE/ID SET on the headphones once.
The headphones detect the frequency of the transmitter
automatically. The beep sound stops when the headphones
start receiving signals.
RF signal transmission area
The approximate RF signal transmission area from the transmitter is up to 30 m.
The transmitter detects the optimum frequency automatically when the headphones
are removed from the transmitter. The sound may be interrupted if the headphones
are out of RF signal transmission area or reception conditions deteriorate. In this case,
move closer to the transmitter or press TUNE/ID SET on the transmitter and
headphones to have them detect the optimum frequency again. See "If a beep sound
is heard from the headphones" on how to detect the optimum frequency.
Notes
• Because this system transmits signals at 2.4 GHz, sound may be interrupted if interference
occurs. This is due to radio frequency characteristics, and is not a malfunction.
• Any noise you hear through the headphones may vary depending on the transmitter position
and room conditions. It is recommended that you place the transmitter in a location that
produces the clearest sound.
• Sound may be interrupted if the transmitter is used with other wireless apparatus using
2.4 GHz frequency, or a microwave oven.
