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
immediately. Do not operate your model again until
you are certain the problem has been corrected.
Caution: Control of your model is impossible without
sufficient 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 BEC),
you should discontinue use when the top speed sharply
decreases or you'll quickly lose control of your model.
For safe and reliable performance of your R/C model, please
carefully read and follow the guidelines below.
1. Radio control models are not toys. They are capable
of inflicting 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 swim-
mers, full-size boats and wildlife. Also, watch carefully for
fishing lines that may get tangled in the propeller.
The Federal Communications Commission (FCC) requires
that changes in transmitter frequency must be preformed
only by an authorized service technician (Horizon Service
Center). Any transmitter frequency changes made by a non-
certified technician may result in a violation of the FCC rules.
