7. Notes on batteries and rechargeable batteries
• Keep batteries/rechargeable batteries out of the reach of children.
• Do not leave the batteries/rechargeable batteries lying around openly. There is a risk of them being swallowed by children or pets.
If swallowed, consult a doctor immediately!
• Batteries/rechargeable batteries must never be short-circuited, taken apart or thrown into fire.
There is danger of explosion!
• Leaky or damaged batteries/rechargeable batteries may cause caustic burns if they come into contact with the skin. Therefore,
you should use suitable protective gloves.
• Do not recharge non-rechargeable batteries. There is a risk of fire and explosion! Only charge rechargeable batteries intended for
this purpose. Use suitable battery chargers.
• Please observe correct polarity (po and negative/-) when inserting the batteries/rechargeable batteries.
• If the device is not used for a longer period of time (e.g. when stored), remove the inserted batteries/rechargeable batteries from
the remote control and the model to avoid damage caused by leaking batteries. Recharge rechargeable batteries about every 3
months, as otherwise they might be fully discharged due to self-discharge, which renders the rechargeable batteries useless.
• Always replace the whole set of batteries/rechargeable batteries. Do not mix full batteries/rechargeable batteries with half-full
ones. Always use batteries/rechargeable batteries of the same type and manufacturer.
• Never mix batteries and rechargeable batteries! Either use batteries or rechargeable batteries for the remote control.
The operation of the remote control (transmitter) with rechargeable batteries instead of normal batteries is possible.
However, the lower voltage (batteries = 1.5 V, rechargeable batteries = 1.2 V) and the lower capacity of rechargeable
batteries reduce operating time. Normally this does not matter, since the operating time of the remote control exceeds
that of the model.
If you use normal batteries in the remote control, we recommend using high-quality alkaline batteries.
When rechargeable batteries are used, the range can be reduced.
8. Charging rechargeable batteries
The rechargeable AA batteries required for the remote control are usually empty upon delivery and must be charged.
Please note:
Before a rechargeable battery reaches maximum capacity, several complete discharge and charge cycles are neces-
sary.
Discharge the rechargeable batteries regularly, as charging half-full rechargeable batteries several times can cause
the so-called memory effect. This means that the rechargeable battery loses its capacity. It no longer provides maxi-
mum capacity. Operating time of the model or the transmitter is reduced.
If you use several rechargeable batteries, purchasing a high-quality charger may be worthwhile. Such a charger usu-
ally has a quick-charging feature.
