Maintenance and Troubleshooting
Due to its rugged design, the MHS550 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.
