c) Charging rechargeable batteries in the transmitter
When using rechargeable batteries, you can attach a charging cable to the charging socket (see ill. 3, pos. 4) and charge the rechargeable batteries in the
transmitter. The transmitter must be switched off. Make sure the polarity of the connector plug is correct. The inner contact of the charging socket must be
connected to the positive terminal (+) and the outer contact to the negative terminal (-) of the charger. The charging current should correspond to approximately
1/10 of the capacity value of the inserted rechargeable batteries. Rechargeable batteries with a capacity of 2000 mAh require a charging current of approx. 200
mA, the charging time being approx. 14 hours. In order to avoid damage to the internal conductor paths and connections, please do not use any quick chargers.
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.
Connect the charger only if rechargeable batteries (1.2 V/cell) have been inserted in the transmitter. Never try to recharge normal batteries (1.5V/
cell) with a charger.
Caution!
The speed controller in the model is equipped with an effective protective circuit which prevents the drive motor from starting unintentionally.
Nevertheless, before using the transmitter, always make sure that the motor speed control stick (see ill. 2, pos.10) is in the "motor off" position. For
this purpose, the control stick has to be pushed down completely or pulled towards you as far as possible. As opposed to the control functions of the
rudder, the motor speed control stick is not equipped with a return spring, so it keeps its position.
When the rechargeable batteries are charged or new batteries have been inserted, pull out the transmitter aerial completely and switch on the transmitter using
the power switch (see ill. 2, pos. 6) to test it. The LED display (see ill 2, pos. 7) lights up green to indicate that the transmitter is sufficiently supplied with power.
If the power supply is not sufficient for the transmitter to work properly (less than 8 V), the LED changes from green to red. In this case, you should stop operating
your model as quickly as possible. To continue operating the remote control, recharge the batteries or insert new batteries.
In order to avoid the memory effect of NiCd rechargeable batteries, you should connect a charger only when the rechargeable batteries are completely
discharged.
d) Reverse switches
The remote control is equipped with reverse switches for each servo function (ill. 2, pos. 12). The reverse switches are numbered 1 - 4. They affect the following
servo functions:
1 = Aileron
2 = Elevator
3 = Motor speed
4 = Rudder
By default, all reverse switches are correctly set for the model. In chapter "11. Completion of the model" you are asked to check the direction of the
servos that control rudder, elevator, aileron and motor speed. Should you have switched a reverse switch unintentionally or if you want to adjust the
transmitter to your personal steering habits, switch the reverse switches to reverse the direction of the servos.
