You can charge the receivers and the removed rechargeable batteries

in the Sennheiser L 300 10-10 charger. An individual receiver can be

charged in the Sennheiser TI 830 infra-red transmitter.

왘Before using the rechargeable batteries for the first time,

charge them for at least 3 hours.

Charging the receiver

왘Place the receiver into the charging compartment of the L 300 10-10

corresponding LED lights up green.

For further information on charging, refer to the instruction manual of

the L 300 10-10 or to the instruction manual of the corresponding

Sennheiser infra-red hearing system.

Charging the rechargeable battery separately

When a rechargeable battery is discharged, you can use the receiver

with an optional spare rechargeable battery:

왘Remove the discharged battery from the receiver and recharge the

battery in the L 300 10-10 charger or in the Sennheiser infra-red

transmitter.

To remove the receiver’s discharged battery:

왘Pull the battery out of the receiver’s battery

compartment.

To insert the receiver’s battery:

왘Insert the battery into the receiver and slide

the battery into the battery compartment as

far as it will go.

• With a fully charged rechargeable battery, the operating time

is up to 12 hours.

that it is fully charged when needed. The intelligent battery

charging technology prevents overcharging.
