Issue:
Cause and solution:
No
• Check that the transmitter AC power adapter is fully inserted into the wall
sound
outlet and the power cord from the AC adapter is firmly connected to the
transmitter power input jack.
• Confirm that the headphones are turned ON and tuned to the transmitter –
the green tuning indicator light should be glowing steadily.
• Check that the AAA batteries are fresh and inserted with correct polarity
(+, –).
• Check that the audio source component (stereo, TV, etc.) is turned on and
transmitting sound as it normally should.
• Check that the headphones volume is turned up.
• If you are using a Tape 2 Monitor output from your receiver/amp as the
audio output, check that you have pressed the Tape Monitor/Tape 2
button on the front of the receiver. This will turn on the Tape 2 outputs,
which may not have been active.
Cause and solution:
Issue:
• Check that the transmitter audio level indicator light is flickering
No
intermittently. If the light is not intermittent and you know you are using a
sound/
fixed level audio source, play music on your audio source while adjusting
distortion/
the input level control on the back of the transmitter. Adjust the level
static
control until the light begins to blink intermittently again.
or
• If the transmitter is connected to a variable output, make sure the output
level control wheel is turned up (all the way to the right - your right when
looking at the front of the transmitter), and adjust the volume on the audio
source up or down as necessary to make the light flicker intermittently.
• Change the position of the channel select switch (1, 2 or 3) to change the
operating frequency. The headphones will detect the loss of signal and
retune automatically. However, you can also press the power/scan control
once to make the headphones retune.
• Change the location of the transmitter. Place it as high and away from
obstructions as possible. Avoid placing the transmitter directly on top of or
behind a TV.
• Move the transmitter and headphones closer together. Sending the signal
through certain materials, such as glass, tile, and metal, can decrease the
effective transmitting distance of the system.
