The batteries that provide power to your system do not need to be “drained”. Simply follow
the procedure below within 48 hours before each use:
1. All radios should be OFF.
2. Plug AC Charger/Adapter into a wall outlet and attach to Radio Charging Jack.
3. Charge each radio for 10-12 hours.
4. The transceiver battery charges fully in 10-12 hours. To prevent overheating of the
