The charging process comprises quick charging and trickle charging modes.
Quick charging: This process takes approx. 2 hours if the battery is empty, it
charges the battery to a charge level of approx. 100%.
Trickle charging: At the end of the quick-charging phase, the system switches
over to trickle charging mode with a lower charging current
so that the DRC-MJ D3 hand-held transmitter can remain
connected to the charger for any period of time. This also
indicated by an acoustic signal.

Important
To ensure sufficient charging of empty batteries, the DRC-MJ D3 hand-held
transmitter must be connected to the charger for at least 2 hours. The full
battery icon is not sufficient after the charger plug is disconnected, as this icon
already appears after a only brief period of charging.
