Symptom
Cause
Solution
The unit does not turn
on.
The
3
and
#
polarity orientation of the batteries is
incorrect.
Insert the batteries with the correct polarity
orientation.
The batteries are getting low.
Replace the batteries with new ones.
The battery terminals are dirty.
Clean the
3
and
#
terminals with a cotton swab.
The unit does not turn
off.
The POWER/MUTING button is locked.
Release the locked status in the PWR LOCK
menu.
The batteries become
drained quickly.
The batteries are getting low.
Replace the batteries with new ones.
Manganese batteries are being used.
Use alkaline batteries. The battery life of a
manganese battery is less than half that of an
alkaline battery.
The device is being used under cold conditions.
The batteries drain quickly under cold conditions.
The channel cannot
be changed.
The unit is not in transmission stopped mode.
Turn off the unit, and then turn it on again while
holding down the SET button to switch to
transmission stopped mode.
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 transmitter is not transmitting signals, or the
transmission output is weak.
Confirm that the transmitter is turned on.
Alternatively, reduce the distance between the
transmitter and receiver.
The transmitter is set to line level input.
Switch to microphone input.
The compander mode setting on the transmitter is
different from that on the receiver.
Use the same compander mode setting on both
the transmitter and receiver.
The transmitter is muted.
Press the POWER/MUTING button on the
transmitter to release the muted state.
The sound is weak.
The attenuation level on the transmitter is too high. The input level of the transmitter is low. Set the
attenuation of the transmitter to an appropriate
level.
The volume on the amplifier or mixer is low.
Adjust the volume to an appropriate level.
The transmitter is set to line level input.
Switch to microphone input.
The compander mode setting on the transmitter is
different from that on the receiver.
Use the same compander mode setting on both
the transmitter and receiver.
The sound is
distorted.
The attenuation level on the transmitter is too low
or is set to 0.
The input level is extremely high. Set the
attenuation on the transmitter so that the audio is
not distorted.
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 compander mode setting on the transmitter is
different from that on the receiver.
Use the same compander mode setting on both
the transmitter and receiver.
There is sound
interruption or noise.
The channel setting on the transmitter is different
from that on the receiver.
Use the same channel setting on both the
transmitter and receiver.
Two or more transmitters are set to the same
channel.
Two or more transmitters cannot be used on the
same channel. Refer to the frequency list stored
on the supplied CD-ROM, and reconfigure the
channel on each transmitter.
The transmitters are not set to the channels within
the same channel group.
The channel plan is set so that no signal
interference occurs when two or more transmitters
are used simultaneously. Set each transmitter to a
different channel within the same channel group.
Adjacent channels are being used.
Use the channels separated by at least two
channels (250 kHz).
