Uniden MHS75 Maintenance and Troubleshooting, Setting the UIC channel mode, Common questions

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-Lockkey 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.
