Pro Boat Pistol Grip Radio - Manual (Page 2)

Your AMR-2/27 Receiver has Battery Eliminator Circuitry
(B.E.C.). The receiver gets its power from the model’s NiCad bat-
tery pack, thus saving the weight of an additional receiver bat-
tery. NiCad batteries from 4.8-8.4V (4-7 cells) can be used safely.
Higher voltage packs may damage the receiver and servos.
ATTENTION: A A Make sure the male and female connectors have
the correct polarity (+/–) before connecting. The servo lead and
receiver case are molded so that the lead can only be inserted
correctly. Be sure to orient the servo plug correctly for proper
insertion.
You may use a separate battery to power the receiver (such as
for some electric boats or in gas-powered vehicles). A NiCad
pack plugged into the BAT
pack plugged into the BA pack plugged into the BA T socket on your receiver will operate
your receiver.
If you use a mechanical speed controller, please ensure that it
has the correct connector for a B.E.C. system (red connector).
See F
IGURE A for a typical setup.
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 setup and check your speed controller’s manual for
correct installation.
You should use the black rubber servo cushions whenever pos-
sible to decrease your servo’s sensitivity to vibration.
IV. OPERATING YOUR MODEL
It is important to learn the proper sequence for switching ON/
OFF your radio system:
B EFORE O PERATION : Switch on the transmitter, then the receiver.
A
FTER
O
PERATION
: 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.
