7. Notes on Batteries and Rechargeable Batteries
Despite the fact that handling batteries and rechargeable batteries in daily life nowadays is a matter of fact,
there are still numerous dangers and problems involved.
Ensure that you observe the following information and safety measures when handling batteries and
rechargeable batteries.
• Keep batteries/rechargeable batteries out of the reach of children.
• Do not leave any batteries/rechargeable batteries lying around openly. There is a risk of batteries being swallowed
by children or pets. If swallowed, consult a doctor immediately!
• Batteries/rechargeable batteries must never be short-circuited, disassembled or thrown into fire. There is a danger
of explosion!
• Leaking or damaged batteries/rechargeable batteries can cause chemical burns to skin when touched without the
use of adequate protective gloves.
• Do not recharge normal batteries. There is a risk of fire and explosion! Only charge rechargeable batteries intended
for this purpose. Use suitable battery chargers. Batteries (1.5 V) are meant to be used once only and must be
properly disposed of when empty.
• When inserting batteries/rechargeable batteries or when connecting a battery pack or a charger, observe the correct
polarity (note plus/+ and minus/-). Wrong polarity may damage the transmitter, the airplane and the rechargeable
batteries. There also is a risk of fire and explosion.
• Never leave batteries unattended while charging them.
• Always replace the entire set of batteries or rechargeable batteries in the transmitter. Never mix fully charged batter-
ies/rechargeable batteries with partially discharged ones. Always use batteries or rechargeable batteries of the
same type and manufacturer.
• Never mix batteries and rechargeable batteries! Use batteries or rechargeable batteries for the transmitter.
• If not used for a longer period of time (e.g. for storage), remove the batteries (or rechargeable batteries) inserted in
the transmitter to avoid damage from leaking batteries/rechargeable batteries.
The transmitter can be operated with rechargeable instead of regular batteries.
However, the lower voltage (batteries=1.5 V, rechargeable batteries=1.2 V) and the lower capacity of
rechargeable batteries do lead to a decrease of the operating time. Normally this does not matter, since
the operating time of the transmitter exceeds that of the model.
When using batteries in the transmitter, we recommend the use of high-quality alkaline batteries.
When rechargeable batteries are used, the range can be reduced.
