1. The cord with the power plug at both ends is the Tx charging use cord. To charge the transmitter, connect
this cord to Tx of the charger and "A" of the transmitter.
2. The cord with the power plug at one end and the 3P connector at the other end is the RX charging use cord.
When charging the NR-4C receiver use nickel-cadmium battery, connect the power plug end of this cord to
RX of the charger and the 3P connector end to the NR-4C.
3. Plug the charger plug into an AC line receptacle (AC 115V, 220V, 240V).
4. Charging is performed with the above operations. At this time, the LED of the charger will be illuminated to
indicate that charging is being performed.
5. Be absolutely sure that all the connections are correct. If the NR-4C receiver use nickel-cadmium battery is
connected to Tx, the battery may be damaged by overcharging.
6. The special charger can charge the transmitter battery and receiver battery simultaneously or independently.
PERFORMANCE TEST AND MOUNTING PRECAUTIONS
1. Verify that the receiver and servos are connected in accordance with Figure 3. Then, make the transmitter
antenna as short as possible and extend the receiver antenna and attempt operation from a distance of 20m~
30m. Operation is normal if all the controls are functioning properly. Perform this test within a maximum of
5 minutes time. Never perform this test when the transmitter antenna is not mounted to the transmitter. Other-
wise the transmitter will be adversely effected.
2. Be careful that the receiver does not directly touch other mechanisms of the aircraft itself. Moreover, wrap the
receiver in sponge rubber so that it is not subjected directly to engine vibrations. (In the case of boat use, cover
the sponge wrapping with a vinyl bag and tie securely at the point at which the cord enters so that no water can
enter the receiver.)
