is being used under cold
conditions.
The batteries drain quickly
under cold conditions.
The channel
cannot be
changed
An attempt was made to
change the channel by
pressing the SET button only.
There is no
sound.
The channel setting on the
transmitter is different from
that on the receiver.
Use the same channel setting
on both the transmitter and
receiver.
The sound is
weak.
The attenuation level
on the transmitter is
too high.
The input level of the transmitter
is low. Press the button on the
transmitter in attenuation level
setting mode to decrease the
attenuation level.
The line input is selected
on the transmitter.
Pull the cable out from LINE IN.

The attenuation level on
the transmitter is too low.
The input level of the receiver is
extremely high. Press the + button
on the transmitter in attenuation
level setting mode to increase the
attenuation level.
The transmitter and the
receiver are set to
different channels.
Set the transmitter to the
same channel.
Headphones with a mon-
aural min jack is used.
Use the headphones with a
stereo mini jack.
RF interference
.Try a different channel. Make sure
both units are on the same
channel.
.Try to position the antennas at a
45° angle in relation to each other.
There can be a lot of RF
interference outdoors.
.Try moving indoors, where there
is less RF interference.
.Keep the units' antennas at least
2'(0.6m) away from conductive
objects like metal and water.
.Overhead telephone lines,
fluorescent lighting, and metal
fences can all cause interference.
.Turn off all nearby computers
and mobile phones.
The audio is
noisy or
distorted. This
can include drop
outs, white
noise, bursts,
pops and clicks.
The audio is
noisy or
distorted. This
can include drop
outs, white
noise, bursts,
pops and clicks.
RF signal is weak.
Make sure there is an unobstructed
line of sight between the
transmitter's and the receiver's
antennas.
Keep in mind that your body,
clothes, and onstage sets are
possible obstructions.
Make sure the receiver and
the transmitter are within
328'(100m) range.
If there are obstructions, you
may need to move closer.
The input level on the
camera, recorder, or
mixer is too high.
Turn down the audio input level on
your camera or recording device.
Lower the audio output level on
the receiver.
Turn down the gain on your mixer.
If there is no adjustment on the
device, and the level is still high,
adjust the microphone level on the
transmitter. Keep this level as high
as possible without distortion.
