If there is interference to the reception of the headphones, you can change the
transmission frequency by switching the channels. With the switch (12) on the bot-
tom of the transmitter it is possible to set 3 different channels. Once you have set a
different transmission frequency, turn the channel selector (4) until the green light of
the channel diode shows you the best possible reception.
1. Insert two batteries of type • AAA • into the battery compartment (7). Please
ensure the correct polarity as shown on the bottom of the battery compartment.
2. Switch the headphones off.
3. Connect the power pack to a 230V/50Hz socket and connect it to the transmit-
ter.
4. Connect the charging sockets (8 and 15) on the headphones and/or on the
transmitter using the charging cable (20).
When using the device for the first time, the batteries should be charged for a
period of 12 hours. Later a charging time of approx. 8 hours is sufficient.
Charging is indicated by the charging diode (11).
Important note:
•
Do not charge the batteries for more than 48 hours!
•
Before charging it is important to make sure that only rechargeable batteries
are inserted. It is not technically possible to charge batteries that are not
rechargeable, and any attempt to do so can damage the device!
5. Remove the charging cable again when charging is complete.
