Uniden MHS75 Radio Owner’s Manual
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.
