Maintenance And Troubleshooting - Uniden MHS115 Owner's Manual

Maintenance and Troubleshooting

Due to its rugged design, your radio 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.

Things to try
Charge the radio.
• Don't use the charger when the ambient
temperature is below 5° C (41° F) or
above 40° C (104° F).
• Make sure the charging contacts on the
radio and charger are clean.
• Replace the battery.
• Make sure you are not in Weather or
Scan mode.
• Make sure you are not trying to transmit
on a receive-only channel or transmit at
the wrong power level for this channel
(see the channel lists starting on page
26).
• Check the battery power level; if it's
low, charge the battery before trying to
transmit.
• Make sure the duration of each
transmission is less than 5 minutes.
Adjust the squelch level; it is probably too
high.
Clear water from the speaker grill.
Adjust the squelch level; it is probably too
low.
Check your UIC channel settings: does
the area you are in use different channel
assignments?
