User manual FUTABA FP-4DN

[. . . ] Therefore mixing with other Futaba receivers and servos will not affect the operation. Frequency changes are easily accomplished, because of the plug-in socket for the crystals. Throttle control Lever location can be easily changed from left to right side. Neck strap and Hook is provided for convenient handling. RECEIVER 1.

Mark (**) = Factory tuned convertion of crystal is required. 5 HANDLING THE RECEIVER AND SERVOS 1 . The FP-R6D receiver incorporates an 8 Bit integrated circuit and is made into 6-channel operation. The same integrated circuit is also used for Four (4) and Five (5) channel operation. The Block connector sockets that connects the different Servos are an integral part of the receiver. The Block Connector sockets are polarized and each position is designated on the receiver case. Therefore check carefully before connecting the Servos. Particularly care must be taken since the power supply relay connector is Red and the Aileron relay connector is BLACK. Since each Servo is built to the same specifications, any Servo can be used for any purpose. There is a FP-S5L (Reversible Servo Red Label) included in each set. This Servo is convenient for throttle control on shoulder wing models. 6 6. Connectors are made as shown in the above diagram. Please make certain that each connector is fully plugged in and that the Aileron section etc. , and the power supply switch harness is correctly identified. After making certain that the connections are correct according to the above diagram, turn on the transmitter switch and then put the receiver switch to ON position. At this point each Servo will stop at the Neutral position. Move each stick and Trim lever and check to see if the specific Servo is actuated correctly. When each section is tested for movement, please make certain that both the Transmitting and Receiving antennas are fully extended. If the Transmitting antenna is shortened and the Transmitter switch is left ON for more than 5 minutes, the transistors in the Transmitter will be damaged. If the system does not operate after completely assembling the batteries, switch harness and Servos for the receiver and the Transmitter, the problem may be due to damage during shipment. Do not attempt to open any of the units, but return them for exchange. 7 NI-CAD BATTERIES AND RE-CHARGING FP-4DN, FP-5DN, FP-6DN and FP-5 Transmitters are equipped with eight (8) pen-light type Ni-Cad batteries. For the Receiver & Servos, Four (4) Ni-Cad batteries are provided in the set.
