BATTERY CHARGING INSTRUCTIONS
(Transmitter and Receiver Nicd Batteries)
Before operating your system, recharge the Nicd batteries as follows:
•Connect the DIN connector of the FBC-8B (2)
battery charger to the transmitter charging
socket, and connect the 3P connector to the
airborne NR-4J Nicd battery pack and plug the
battery charger into a 120VAC outlet as shown
in the figure.
•The TX and RX LEDs light to show that bat-
teries are being charged. The Nicd batteries can
also be charged through the DSC-CHG cord by
connecting the CHG adaptor to the charger as
shown in the figure. This allows the NR-4J
airborne Nicd pack to be charged without
removing it from the model.
•Normally recharge the battery for about 15
hours. If it has not been used for some time,
discharge and recharge it two or three times,
then charge it a full 15 hours.
•The amount of time remaining before the bat-
teries must be recharged can be estimated by
checking the integrated timer at the moment
the TX battery alarm sounds (antenna ex-
tended).
• Leaving batteries in the discharged state for a
long time will adversely affect their capacity
and life.
•The TX and RX Nicd batteries can be charged
simultaneously or independently.
•A fully-charged TX battery can be used for
about 10 flights of 10 minutes each. The air-
borne NR-4J Nicd battery pack can be used
for about 7 flights when 6 servos are used and
about 4 flights when 10 servos are used.
• The DSC (Direct Servo Controller)
system connects the signals from
the transmitter directly to terminal
C of the receiver through the DSC
cord and controls the servos with-
out transmitting radio waves. \\ is
extremely convenient when other
dyers are on the same frequency,
or during contests, etc.
•When the DIN connector of the
DSC cord is connected to the DSC
socket, the power to the encoder of
the transmitter is turned ON auto-
matically The
transmitter
power
switch is l e f t OFF.
• When not using the DSC, discon-
nect the DIN connector to reduce
battery drain.
• To operate the servos, turn on the
airborne switch (only).
•When the DSC cord
is connected, the receiver
power supply voltage
is measured
(no load).
The voltage is displayed
by "Ex" on the lower
right side of the initial
LCD screen.
