Operation Manual

General Section 7
Power Supply
The battery tray in the transmitter is equipped with a
9.6v battery.
Different battery types are available to be selected.
Into the battery mounting for the receiver, insert four
AA cells of 1.2v and between 500 and 600mAh.
Instead of the battery mounting, or in addition, a 4.8v
battery with miniature plug can be used, see page 5.
Pay attention to the full battery voltage. If the rudder
moves noticeably more slowly or display the goes
under 9.6v back then stop operation and load new
batteries (or recharge).
Charger devices and batteries - see Graupner main
catalogue telex.
Your contribution to environmental protection:
Do not throw to used up batteries into the domestic
refuse, but take these to an appropriate collecting
point, in order for them to be recycled or disposed of
in an environmentally friendly way.
Charging of the Transmitter battery
The rechargeable transmitter battery can be charged
in the Transmitter using the socket on the side of the
case. The set must be switched OFF while charging.
When using the automatic MULTILADER 5B or 6E
the connection is made by charging cable Part No.
3022. For the MULTILADER 5 it is necessary to use
the polarised charging cable Part No. 3040.
The remote control system is equipped with a
reverse connection protection circuit for charging of
the Transmitter battery. Thus damage is prevented
by incorrect polarity or short-circuit. In order to
disable this reverse current protection (e.g. for
measuring purposes or when connecting an
automatic loader), it is necessary that the enclosed
two-pole plug link is attached directly to the link pins
as short circuiting bridge.
During rapid charging the transmitter battery
charging current must not exceed 1.5A.
Charging the receiver battery.
The charging cable Part. No. 3021 for
MULTILADERS 5B and MULTILADER 6E can used
to connect the receiver battery directly to the
charger. If the battery is in the model, then charging
cables Part. No. 3023, 3046, 3377, 3934 or 3934,3
are attached making use of the connector integrated
into the receiver switch harness. For the universal
battery charger MULTILADER 5 the polarised
charging cable Part. No. 3041 is necessary.
The period of operation of receiver batteries depends
heavily on the battery type and on the frequency of
servo movements and their load. In the PCM mode
the "Fail Safe" function can be activated, which will
display when the receiver battery falls below to a
certain voltage, see page 25.
