FOR SAFETY
Do not throw the nicd battery into a fire or heat the nicd battery. Also, do not
disassemble or rebuild the nicd battery.
Breakage, overheating, and electrolyte leakage may cause injury, burns, or blindness.
MANDATORY ITEMS
When not flying the model, store the digital proportional R/C set with the nicd
battery in the discharged state. Recharge the nicd battery before the next
flight.
If a partially discharged nicd battery is recharged many times, its memory effect will reduce
the flight time substantially and may cause a crash, even if the battery is recharged.
Nicd battery electrolyte
The electrolyte in the nicd battery is a strong alkali and can cause blindness if it gets
in the eyes. If you get the electrolyte in your eyes, immediately wash your eyes with
water and see a doctor. If you get the electrolyte on your skin or clothes, it may cause
a burn. Immediately wash it off with water.
CAUTION
PROHIBITED ITEMS
Do not store the digital propor-
tional R/C set in the following
places:
-Where it is very hot (40C/104F or
more) or very cold (-10C/-14F or less).
-Where the set will be exposed to di-
rect sunlight.
-Where the humidity is high.
-Where there is strong vibration.
-Where it is dusty.
-Where there is steam and heat.
Storing the digital proportional R/C set in
the places above may cause distortion
and trouble.
MANDATORY ITEMS
If the digital proportional R/C set
will not be used for a long time, re-
move the nicd batteries from the
transmitter and the model and
store them in a dry place.
If the batteries are left in the transmitter
and model, the battery electrolyte may
leak out and degrade the performance
and shorten the life of the transmitter and
model.
Nicd battery recycling
Used nicd batteries are an important resource. Stick tape over the terminals and take
the used batteries to a nicd battery recycling center.
