DIAGNOSTIC MESSAGES

In addition to the low battery condition, a flashing red status LED may also indicate fault conditions

Should your radio apparently not operate correctly, replace the battery with one known to be fully charged. If the condition persists, or the radio emits an unexpected continuous pattern of audio beeps, or will not transmit or receive as it does normally, return the radio to your Maxon dealer.

UNPROGRAMMED CHANNEL

If your radio has been set-up for less than the maximum number of channels, turning to a blank channel will cause your radio to beep and the status LED will flash red, indicating that the channel is unusable.

RECEIVE ONLY CHANNEL

Your radio may be set-up to receive on a channel but not to transmit. If PTT or call functions are started on such a channel, the radio will beep and the LED will flash red.
