7 CLEANING AND MAINTENANCE OF
YOUR RADIO
7.1 Cleaning the radio
Carefully rub the radio using a soft, clean cloth that does not have
loose bers. If the radio is very dirty, slightly dampen the cloth with a
mixture of water and a neutral soap.
Do not use detergents, alcohol, solvents, or abrasives.
While cleaning the radio, always keep the rubber ap over
the side connectors, the antenna, and the battery well in
place. Do not under any circumstances allow the connectors
or electrical contacts to get wet.
7.2 Connectors
When the connectors are not being used, they must be covered with
their protective rubber ap.
Only use original accessories or those approved by CTE
International, otherwise you may damage the radio.
8 TROUBLESHOOTING
Your 445 BT is designed to provide you with years of optimal
performance. If for some reason a problem should arise we suggest
you consult this chapter before contacting your local service centre.
8.1 Reset of functions
If your transceiver experiences a logical malfunction (improper
symbols on the display, blocking of functions, etc.), it may not be
experiencing a true failure, but rather a problem caused by external
factors. For example, it may have an incorrect setting brought on by a
noise or spikes in the electrical system during battery recharging. In
such cases, you can reset the transceiver to its factory-programmed
settings, deleting memories and resetting all functions. To do this:
1. Turn off the transceiver.
2. Hold down the
F button, and at the same time, turn on the
transceiver; all of the icons and symbols will appear simultaneously
on the transceiver.
3. Release the
F button. All settings will return to the factory-
programmed ones. For example, the radio will be reset on the
channel 1, high transmission power will be selected, etc.
Before you reset the radio, we suggest you write down all of the
settings you have previously entered, as they will be cancelled
during the reset.
