Section 7: Infrared Transmission System
7.2.2 Using the Infrared Receiver
1. Connect the headphones to the
jack (1).
Make sure to turn the VOLUME control (5) to its minimum posi-
tion to avoid damaging your hearing by excessive sound levels.
2. To switch power to the receiver on, press the <ON> key (2) on the receiver side panel.
The BATTERY LED (3) provides the following information:
3. Use the LANGUAGE SELECT rotary switch (6) to select the desired language from the list of interpreted languages
provided by the organizers (or by ear, if no such list is available).
4. Use the VOLUME control (5) to set the volume level of your headphones just loud enough so you can hear clearly
what is being said.
Important:
•
Do not turn the headphones volume up any higher than necessary. Listening to excessive sound lev-
els on headphones may damage your hearing.
•
(Refer to fig. 10 on page 37.) Never cover the collecting lens (4) above the infrared receiving diode. Cov-
ering the lens (4) will cut the signal and may cause the receiver to switch off automatically.
Note:
The signal may fade in some spots within the conference room due to interference or shadow effects. If that
happens, move away from such a spot.
5. If the BATTERY LED (3) on the receiver top panel starts flashing, the battery will be dead soon. Return the receiver
to conference staff. They will give you a receiver with a fully charged battery.
6. You cannot switch power to the receiver off. The receiver will switch off automatically 30 seconds after the infrared
signal has stopped.
Note:
The receiver will also switch off automatically before the battery is completely discharged to avoid damaging
the battery.

The infrared receiver is delivered with a
280 mAh
9 V NiMH rechargeable battery installed.
Important:
