TRANSMITTER
The control LED (Item 4) indicates the condition of the DUOPHON®
transmitter:
green - operation,
green blinking once - charging,
green blinking twice - buffering,
red blinking - charging necessary
(Remaining operating time
at least 5 minutes),
off - Battery discharged or
transmitter switched-off.
Recharging (Item 7) is effected stationary via the Power Supply Set
(230 V /12 V ) or from the car battery (Car Adapter 12 V/12 V or 24

After about 14 hours’ charging the battery is fully charged and the
transmitter switches from charging to buffering. The transmitter can
remain there without the battery becoming damaged by over-
charging.

DUOPHON® receiver will be checked:
When the pointer is in the widely blocked range of the scale
(Item 17) the batteries have to be exchanged.
The receiver is equipped with eight 1.5 dry cells and has an
operating time of at least 100 hours.
