Only charge rechargeable batteries intended for that purpose!
When connecting a charge cable, imperatively observe the correct polarity of the connecting plug. The inner con-
tact of the charge socket has to be connected to the plus connection (+) and the outside contact to the minus
connection (-) of the charger.
The charging current should be approx. 1/10 of the capacity value of the inserted rechargeable batteries. With
rechargeable batteries with a capacity of 2000mAh this corresponds to a charging current of approx. 200mA and
the charging time is approx. 14 hours.d
Do not use any quick-chargers in order to avoid any damages to the internal strip conductors and connections.
No chargers can be used that briefly interrupt the charging current in order to measure the current rechargeable
battery voltage. A protective diode in the charging current circuit of the transmitter acts as a free battery connection
when the charging current is switched off; thus, the voltage cannot be measured. For such chargers, the rechar-
geable batteries must be charged outside the transmitter.
With NiCd rechargeable batteries a memory effect can occur. If NiCd rechargeable batteries are charged when they
are not fully discharged, their capacity diminishes in the course of time. Thus, such rechargeable batteries must be
discharged with an appropriate charger outside of the transmitter and then charged completely again.
Switching on the transmitter
Attach the enclosed transmitter antenna.
When the rechargeable batteries are charged or when new batteries are inserted, switch the transmitter on.
The red battery control LED lights up and signals adequate power supply of the transmitter.
If the power supply should fall below 9 V, a signal sound will go off. In this case, you should stop operating your
model as quickly as possible. For further operation of the transmitter the rechargeable batteries have to be rechar-
ged or new batteries have to be inserted.
