Your NER-102 Receiver has Battery Eliminator Cir-
cuitry (B.E.C.). The receiver gets its power from the
model’s Ni-Cd battery pack, thus saving the weight of
an additional receiver battery. Ni-Cd batteries from 6V-
8.4V (5-7 cells) can be used safely. Higher voltage packs
may damage the receiver and servos.
ATTENTION: Make sure the male and female con-
nectors have the correct polarity (+/–) before connect-
ing. The servo lead and receiver case are molded so that
the lead can only be inserted correctly. Be sure to ori-
ent the servo plug correctly for proper insertion.
You may use a separate battery to power the receiv-
er (such as for some electric boats or in gas-powered
vehicles). A Ni-Cd pack plugged into the BATT socket
on your receiver will operate your receiver. You may
also use alkaline batteries with an optional battery
holder (part no. JRPA020).
If you use a mechanical speed controller, please
ensure that it has the correct connector for a B.E.C. sys-
tem (red connector). See F
IGURE
A for a typical set- up.
Most electronic speed controllers are set up for
B.E.C. operation and plug directly into your receiver
(Function 2). See F
IGURE
B for a typical set-up and
check your speed controller’s manual for correct instal-
lation.
You should use the black rubber servo cushions
whenever possible to decrease your servo’s sensitivity
to vibration.
III. R/C SAFETY PRECAUTIONS
For safe and reliable performance of your R/C model,
please carefully read and follow these guidelines:
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, you should con-
tact 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 frequen-
cy is clear. If someone else is operating on the same frequen-
cy, 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 Circuit-
ry or B.E.C.), you should discontinue use when the top
speed sharply decreases or you will quickly lose control of
your model.
IV. OPERATING YOUR MODEL
It is important to learn the proper sequence for switch-
ing on/off your radio system:
B
EFORE OPERATION
: Switch on the transmitter, then the
receiver.
A
FTER OPERATION
: Switch off the receiver, then the
transmitter.
This ensures that you will always have a signal to
the receiver, and your R/C model will not operate out
of control when you turn off the transmitter.
