III. R/C SAFETY PRECAUTIONS
For safe and reliable performance of your R/C model, please care-
fully read and follow these guidelines:
1. Radio control models are not toys. They are capable of inflict-
ing serious injury to people and property. Use caution at all
times when operating your model.
2. You are responsible for the safe operation of your R/C model.
You must properly install, test, and operate your model with a
clear sense of that responsibility. Do not take risks that might
endanger yourself or others.
3. Running an R/C car in the streets is very dangerous to both
drivers and models. Avoid running your model in areas
occupied by full-size automobiles. To locate areas where you
can safely operate your model, contact your local hobby shop
for R/C tracks or clubs in your area.
4. When running an R/C boat, keep it away from any swimmers,
full-size boats, or wildlife. Also, watch carefully for fishing
lines that can entangle the propeller.
5. Before operating your model, make sure your frequency is
clear. If someone else is operating on the same frequency, both
models will go out of control, possibly causing damage to the
models, as well as others.
6. If at any time while operating your R/C model you sense
abnormal model functioning, end your operation immedi-
ately. Do not operate your model again until you are certain
the problem has been corrected.
CAUTION: Control of your model is impossible without suffi-
cient voltage for the transmitter and receiver. A weak transmitter
battery will decrease your range of operation and a weak receiver
battery will slow servo movement and decrease your range of
operation. Check your receiver pack voltage often to avoid losing
control of your model. When using a model that operates both
the electric motor and the receiver from the same battery
(Battery Eliminating Circuitry or B.E.C.), you should discontinue
use when the top speed sharply decreases or you will quickly
lose control of your model.
