Maintenance and error management
5.1
Charging the batteries
The batteries of the following components must be recharged
when there are no more segments visible in the corresponding
battery symbols:
●
A 50
receiver (lithium-ion rechargeable battery)
●
F8
wireless headphones (NiMH rechargeable battery)
They can also be charged sooner, however, i.e. even when the
battery symbols show sufficient remaining capacity.
A 50 receiver
NOTICE!
Reduced battery life when not in use
The battery in the A 50 receiver can discharge (self-discharge)
even when the receiver is not in use.
●
You should charge the battery at least once every 6 months.

mitted range
The typical charging time is less than 6 hours. The battery is pro-
tected against overcharging. Therefore the receiver can be left
connected to the power supply once it is fully charged.
The permitted temperature range must be observed during
charging. If the temperature rises above or falls below the limit
values, charging is interrupted until the temperature is within the
permitted range again.
