Changing Batteries
When a battery is becoming weak, a voice
in the earpiece will say “Change battery.”
When this happens, remove the battery from
the headset by pressing the blue battery-release
latch and carefully sliding the battery out of the
earpiece, as shown in Figure 7.

Recharging Batteries
Place a battery in one of the four charging ports on the AC50 battery charger, as shown in Figure 8.
The battery status lights indicate the charging status, as shown on the battery status guide at the bottom
of the AC50 front panel. When a battery charging port is empty, its status light will be yellow. When you
place a battery in a port for charging, its status light will turn red. When a battery is fully charged, its
status light will turn green. Install fully charged batteries in headsets or store them in the storage ports
until they are needed. Battery charging time is approximately 2.5 hours.
