Transmitter Ni-MH Battery
When purchasing a transmitter battery as a spare, etc., use the following:
Part name
HT5F1700B (6V/1700mAh) Ni-MH battery
FT2F2100B (6.4V/2100mAh) Li-Fe battery (Optional)
Please do not use the transmitter batteries HT5F1700B and FT2F2100B, as the receiver's
battery.
Since the transmitter batteries have an overload protection circuit, the output power will be
shut down when the high current load is applied. This may result in runaway or fatal crash.

<Check>
Turn on the power switch and check the LCD battery voltage display. When the batter-
ies are new, the voltage should be about 6V.
If the voltage does not rise, check for faulty contacts or incorrect polarity.
<Disposal of the Dry Cell Batteries>
The method to dispose of used dry cell batteries depends on the area in which you re-
side. Dispose of the batteries in accordance with the regulations for your area.
 Do not use commercial AA size Ni-cd
and Ni-MH batteries.
Quick charging may cause the battery contacts to
overheat and damage the battery holder.
￸ Insert the batteries in the correct polarity.
If the polarity is incorrect, the transmitter may be
damaged.
￸ When the transmitter is not in use, re-
move the batteries.
If the battery electrolyte leaks, wipe off the case
and contacts.
