Troubleshooting
Possible Problem (3): The battery life is based on a duty cycle where the radio is transmitting 5%, receiving 5%, and in standby mode 90% of the time. Usage that differs from this will change the typical battery life expect- ancy accordingly.
Solution :If you use your radio for a longer period of time than the standard duty cycle, you may need to recharge your battery again.
Possible Problem (4): Battery or charger contacts may be dirty.
Solution :Clean battery and charger contacts often.
Alkaline Battery does not last long enough (<10 minutes).
Possible Problem (1): Operating the radio at high power with alkaline batteries.
Solution :When used with alkaline batteries, the radio should operate at low power unless absolutely necessary.
NOTE
It is recommended to operate your radio in Low Power when using alkaline batteries. Using alkaline batteries in High Power might result a Low Battery Alert (3 low pitched tones) shortly after transmitting. This is NOT a malfunction. The alert sounds because alkaline batteries cannot maintain the power needed to transmit at High Power for a long interval. However, APC is immediately activated when this alert sounds. It automatically adjusts the radio’s power requirements to maintain the radio’s operation. Without APC, the radio would instead reset itself and refuse to transmit.
