Operating principle
The

ne to pick up acoustic signals, amplifies them and emits them via the headpho-
ne jack. The amplifier is equipped with a pick up coil which enables you to
receive signals from an inductive loop system.

WARNING: The sound output levels from this system can be very high. It is
recommended that the volume control should be turned to the »OFF« posi-
tion before changing the battery or plugging in or unplugging the headpho-
nes or microphone.
