NOTE:
After turning the headphones back on, CHANNEL 2 is
automatically set as the reception frequency.
Use with cable
To use the headphones with a cable, you must be close
to an audio source and take into account the length of
the cable.
1. Move the ON/OFF switch (9) to the OFF position to
save battery power.
2. Set the WL/OFF mode switch (4) to OFF.
3. Connect the external audio source to the 3.5 mm
stereo TRS connector AUDIO jack (5) on the head-
phones using the correct adapter cable.
4. Adjust the volume on the audio source.
NOTE:
• The volume control (3) on the headphones does not
function in this mode.
• The transmitter/charging station does not need to
be switched on in this mode.
Troubleshooting
Poor or fuzzy sound
• Have you changed the channel? Press the SCAN
channel selection button (2) in order to obtain the
best reception.
• Check the distance to the transmitter. Walls and ceil-
ings reduce the range.
• Are the batteries charged up?
• There may be interference from other radio emit-
ting equipment such as cordless telephones, mobile
telephones or CB radio.
No headphone reception
• Are all the components switched on?
• Is the ON/OFF switch (9) in the ON position?
• Is the mode switch WL/OFF (4) set to WL?
• Are all the electrical connections correct?
• Have the batteries been inserted?
• Is the sound source switched on and is a sound signal
being transmitted? The POWER LED (11) only lights
up when the transmitter is receiving an audio signal.
• Is there still no reception despite having checked all
the points above? Transmitter may be blocked, may
"hang". Disconnect the power supply from the mains
for about 5 sec. Then switch the device back on.
Mono sound
• Are you receiving only a mono signal? Turn the audio
source to stereo.
Interference
• Turn the switch (15) to another channel. Press the
SCAN channel selection button (2) repeatedly until
the sound of the audio source can be heard.
AUTO OFF function
• The transmitter has an AUTO-off function. If the
input signal is very quiet or switched off for approx.
1 min., the transmitter switches off automatically.
Turn up the sound of the audio source or check
whether an audio signal is still being transmitted.
