Setting the UIC channel mode
The radio comes preset to use the channels assigned for
the US. If your current area uses Canadian or international
channel assignments, press the UIC-Lock key to rotate
through the US, Canadian, and international channels.
Maintenance and Troubleshooting
Due to its rugged design, the MHS75 requires very little
maintenance. However, it is a precision electronic instrument,
so you should follow a few precautions:
•
If the antenna has been damaged, do not transmit except
in an emergency situation. Transmitting with a defective
antenna may cause further radio damage.
•
You are responsible for continued FCC technical
compliance of your radio.
•
You should arrange for periodic performance checks with
your Uniden dealer.
