Make sure that the transmitter is switched off. The transmitter
must be turned off while the entire charging process.
Connect the jack of the included AC charger to the charge
socket.
A completely discharged battery requires approx. 15 hours to
be charged.
Polarity of the mc- charge socket
The charging cables available on the market by other manufac-
turers frequently have different polarities. For this reason, you
should only use original Graupner charging cable.
NOTE
The charging socket comes standard with a protection switch that
protects against polarity reversal. Original Graupner automatic char-
gers recognize the battery charge. In order to prevent damage to the
protection switch and to the other components, charging current
should never exceed 1 A.
Low voltage warning
The transmitter battery voltage should be monitored in the LCD
display during operation. In case the voltage drops under a pre-
set threshold, standard setting 3,6 V, an acoustic warning signal
is emitted and in the display appears in a window "battery needs
charging".
Now at the latest, stop operation and recharge the transmitter
battery!
Battery use timer in the display
The battery use timer is shown in the lower left part of the dis-
play.
The battery use time is added at every use. After every charge
the timer is reset to "00:00". This happens only if the battery volt-
age increases at least of 0,3V.
Lithium battery
On the transmitter board there is a fixture for a replaceable lith-
ium battery of type CR 2032.
This battery maintains the date and time settings during a trans-
mitter power supply outage.
