2.2 Charging the teacher and student microphones
First use – for best battery performance
Make sure that the battery is fully charged the first time it is used.
Charging the battery
The charging time depends
on how discharged the battery
is. A discharged battery takes
12 hours to charge fully. The
microphones can be left in the
chargers even when they are
fully charged. The charging
current is automatically
adjusted for the best battery
performance. The microphone
is switched off automatically
during charging.
Battery level indicator
When the battery is becoming flat the LED on the microphone lights
up/blinks red. A battery level indication is also given in the display.
Natural discharging
If the microphone is not used and is not kept in the battery charger,
the battery may discharge completely after about 30 days (this is
normal). Always keep the microphone in the charger to prevent it from
discharging.
