FOR SAFETY
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 recycling
Used nicd batteries are an important resource. Stick tape over the terminals and take the used batteries
to a nicd battery recycling center.
CAUTION
Do not store the digital proportional 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 direct 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.
If the digital proportional
R/C set will not be used
for a long time, remove
the batteries from the
t r a n s m i t t e r a n d t h e
model and store them in
a dry place.
If the batteries are left in the trans-
mitter and model, the battery elec-
trolyte may leak out and degrade
the performance and shorten the
life of the transmitter and model.
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.
Other Precautions
