2) Open the battery compartment at the back of the transmitter by pressing the cover down and
toward the bottom. (See fig 2)
3) Load batteries into the slots paying close attention to the polarity. (See fig 2)
4) Replace the battery cover and turn the power “ON” to see if the indicating arrow will move up. If
the batteries are fresh, the indicating arrow will move to the far right side but if the arrow is in the
low power or lower part of the yellow zone, you had better replace the batteries or recharge your
NiCad batteries. (See fig 3)

B. OPERATION CHECK
1) Gently plug the switch harness and servo connectors into the proper slots of the receiver. The
connectors are polarized, thus, should fit only one-way. If they will not go in one-way, reverse it
and see if it will plug in. Never use excessive force to plug in connectors. (See fig 1).
2) Turn the transmitter power switch “ON” first, then the receiver switch. Always remember to turn
the transmitter on the transmitter before you turn the receiver on, otherwise your receiver may
receive other interfering signals from other radio sources and jitter.
3) Check to see if the servos move when you control the sticks. Move the trim lever to the center
position. (See fig 4)
