Storing and charging the receiver
Do not store your receiver on a glass dummy head, chair
armrest, or similar for long periods of time as this can reduce
the contact pressure of the earbows. Furthermore, with the
earbows pulled apart, the receiver remains switched on.
̈ After use, place the receiver into the transmitter’s charging
compartment as shown on the left, without exerting too
much pressure. The transmitter automatically switches off.
̈ If the receiver is placed correctly into the charging
compartment, the LED µ lights up
̈ Before you use the rechargeable battery for the first time,
charge it until the LED µ lights up green
. This can take a
maximum of 3 hours
. With a fully charged battery, the
operating time is approx. 9 hours.
Note:
y
Always store the receiver in the transmitter’s charging
compartment
to ensure that it is fully charged. The intel-
ligent battery charging technology prevents over-charging.
y
When not using the receiver for extended periods of time,
charge the battery regularly every three months.
