Since a protective diode is integrated in 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, remove the rechargeable batteries
from the transmitter for charging.
In order to avoid damage to the internal conductor paths and connections, please do not use any quick chargers. The
maximum charging current must not exceed 500 mA!
Attention!
Connect the charger only if the rechargeable batteries (1.2V/cell) have been inserted in the transmitter.
Never try to recharge normal batteries (1.5V/cell) with a charger.
c) Switching on the Transmitter
When new batteries or freshly charged rechargeable
batteries have been inserted, switch on the transmitter with
the function switch (see figure 2, item 10) for test purposes.
For this, slide the operating switch from the right (OFF) to
the left (ON).
The red operating control LED (see figure 2, item 13) is lit
and indicates the on/off state of your transmitter. The green
under-voltage display LED (see figure 2, item 7) indicates
sufficient power supply of the transmitter.
If the supply voltage drops below 9 V, the green under-voltage LED starts flashing. In this case, you should
stop operating your model as quickly as possible. To continue operating the transmitter, recharge the
batteries or insert new batteries.
In order to avoid the memory effect of NiCd rechargeable batteries, you should connect the charger only
when the rechargeable batteries are completely discharged.
After you have verified the correct function of your transmitter, switch it off again.
