Futaba 8SGAP - Manual (Page 12)

•BATTERIES AND CHARGING INSTRUCTIONS
•The Direct Servo Controller system connects
the signals from the transmitter directly to
terminal C of the receiver through a wire and
controls the servos without radiating radio-
waves. It is extremely convenient when flying
on the same band or during meets, etc.
•Make the connections shown in Fig.12. Con-
necting the special DSC.CHG cord with tab to
receiver terminal C and installing it to the side
of the aircraft fuselage is very convenient.
•When the DIN connector of the DSC cord is
connected to the DSC connector 29, the
power to the encoder inside the transmitter is
turned on. The transmitter power switch is
OFF.
• When not using the DSC, disconnect the DIN
connector.
• To operate the servos, turn on the receiver
and servo switch.
Before using your system, recharge the Nicd batteries as follows:
•Connect the DIN connector of the FBC8B (2) battery charger
to the transmitter charging socket 29 . Also connect the 3P
connector to the airborne NR-4J Nicd battery and plug the
battery charger into a 120VAC outlet as shown in Fig. 12 . The
airborne batteries can also be charged through the DSC/CHG
harness by connecting the CHG adaptor to the charger as shown
in Fig.12. In this manner, the airborne batteries can be charged
without removing them 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 and then charge it a full 15 hours.
• The transmitter and receiver Nicd batteries can be charged
together or independently.
•A fully-charged transmitter battery can be used for about 10
flights of 10 minutes each. The airborne NR-4J Nicd battery
can be used for about 6 flights when 6 servos are used and
about 4 flights when 10 servos are used.
• If the system is not to be used for some time, it should be fully
charged before storage and recharged monthly to avoid full
discharge and loss of memory settings (ATV, FS, BFS memory,
etc.).

Notes:
(1) First, connect to TX Nicd and red lamp goes on.
(2) Then, connect to RX Nicd after connecting, L.E.D.
changes color from red to greenish red (orange)
which indicates that both TX and RX Nicds are
being charged.
(3) In case of separate charging, L.E.D, color will be:
RX N i c d - G r e e n TX Nicd - Red

• The amount of time remaining before the batteries must be
recharged can be estimated using the Integrating Timer
function of the Tachometer/Timer 2 1 . It is recommended
that this function be used to monitor remaining flying time.
