Using the HDI 830
Replacing and charging the rechargeable battery
̈ Charge the rechargeable batteries in the charging compart-
ment of the L 300 10-10 charger.
For further information on the features and functions of the
charger, please refer to the instruction manual of the
L 300 10-10 charger.
̈ Before using the rechargeable batteries for the first time, charge
them for about three hours.
̈ After use, place the receiver back into the charging compartment of
the L 300 10-10 charger.
The receiver switches off automatically.
When the rechargeable battery is discharged, you can continue to use
the receiver with an optional spare rechargeable battery:
̈ Remove the discharged battery from the receiver and charge it in
the L 300 10-10 charger.
Notes:
– With a fully charged rechargeable battery, the operating time is
up to 12 hours.
– Always store the receiver in the L 300 10-10 charger to ensure
that it is fully charged. The intelligent battery charging tech-
nology prevents overcharging.
– Do not store the 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.
