Troubleshooting and Maintenance
■ Troubleshooting
Specifications
Problem
Solution
The transceiver does
not work when
switched on.
The battery is low. Please recharge the
battery pack and make sure the battery pack
is properly fitted or insert a fresh battery, refit
it if necessary. Swap the battery onto
another radio to check if one is available.
The battery runs out in
a short time.
The battery is no longer in good condition
and needs to be replaced with a new one.
The radio can’t
communicate with other
units in the same user
group.
The radio is out of usable range, is not on
the same channel, is not of the same model
type, or the CTCSS/DCS settings and/or
frequencies are incorrect and do not match.
The radio receives
unwanted
transmissions from
other radio users.
Change the channel of all the radios in the
required group to a quiet channel.
■ Maintenance and Cleaning
Do not carry the transceiver by the antenna or attached audio
accessories. Always turn the transceiver OFF when attaching or
detaching audio accessories. Clean the buttons, control knob and
radio body with a dry cloth when it has been unused for a long time
or becomes dirty.
All stated specifications are subject to change without notice or obligation.
