Turning the key beep on and off
Key beep is the tone that sounds when you press a key or a
button. To turn off the key beep, press the MENU button while
the radio is idle. Select Key Beep and then Off. Press ENTER
to save the new setting.
Using the external speaker/mic jack
You can connect an optional external speaker-mic to this
watertight jack. Unscrew the cap, which is held by the rubber
cap-keeper to prevent loss. Insert the special gasketed plug
and screw down the shell, which assures prevention of water
entering the jack. Two available units are
HHSPM Speaker Mic
VOX100 Headset Mic
For details, consult your Uniden dealer or contact Uniden
directly (see back cover for contact information).
Maintenance and Troubleshooting
Due to its rugged design, the MHS450 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.
