A normal full charging cycle will take approximately 4 hours. The charging circuit continuously monitors
the battery status and switches to trickle charge when the battery is fully charged.
Generally speaking, it is sufficient to charge up all the transmitters at the same time as the Instructor Unit
and Student Unit, to always have a working set. If the range of a transmitter becomes significantly
weaker before the batteries of the Instructor Unit or Student Unit are empty, the battery power level is
very low and must be charged up before continuing with the training.
The transmitter is not equipped with a dedicated battery indicator. However, when the battery is empty,
the power indicator will light continuously. The transmitter will not operate reliable anymore, the battery
needs to be recharged.
