To prevent damage to the internal circuitry and connections, do not use a fast battery charger.
Since a protective diode is integrated in the charging circuit of the transmitter, no chargers can be used that briefly
interrupt the charging current in order to measure the voltage of the rechargeable battery.
In this case, the rechargeable batteries must be charged outside the transmitter.
c) Switching on the transmitter
When the rechargeable batteries have been recharged or new batteries have been inserted, pull out the transmitter aerial complete-
ly and switch on the transmitter using the on/off switch (see ill. 1, pos. 7) for test purposes.
The red power LED (see ill. 1, pos. 13) indicates that the remote control is sufficiently supplied with power.
In order to avoid a memory effect of NiCd rechargeable batteries, you should connect the charger only when the rechargeable bat-
teries are completely discharged.
11. Control stick assignment
The control stick (1) (control function for servo 4) stays in position when you let go
of it.
This function is especially designed for the throttle servo of combustion models.
With electric models, an electronic speed controller can be connected to receiver
output 4 alternatively.
With the remaining three control functions, the control sticks automatically return to
centre position when you let go of them.
Illustration 4a shows idle position for combustion motors and “motor off” for electric
models.
Ill. 4b shows the position for maximum motor performance.
Please note:
In order to assign the throttle control function to the right control stick, the control stick modules have to be taken apart
completely and the connecting wires of the potentiometers have to be resoldered.
Only experienced model makers with sufficient knowledge about remote control systems should carry out such modi-
fications.
Should such a conversion be absolutely necessary and you do not have sufficient knowledge, you can send in your
transmitter to our customer service in Hirschau.
The assignment of the remaining control stick functions depends on the model you operate with your RC system.
