[. . . ] The batteries should also be discharged periodically to prevent a condition called "memory. " If, for example, only two flights are made each time you go flying, the batteries will not have "reached" very far down into their full capacity. After doing this several times the batteries will "remember" and eventually "think" they can supply only enough power for two flights. After two flights the batteries may not provide enough power to operate the system, thus causing a crash. To erase any potential memory, cycle the batteries by discharging, then charging them with a commercial battery cycler, or leave the system on and exercise the servos by moving the transmitter sticks until the servos are moving very slowly, indicating that the battery is discharged. Cycling should be done every one to two months, even during the winter or periods of long storage. If using a cycler with a readout, note the capacity after the batteries have been cycled. If there is a noticeable drop in capacity the batteries should be replaced. Note: Charging your batteries with the special Futaba A/C battery charger is always safe. However, fast-charging with an aftermarket charger is acceptable as long as you know how to properly operate the charger. If not done correctly, fast-charging can damage the batteries. 8 LINK PROCEDURE Each transmitter has an individually assigned, unique ID code. In order to start operation, the receiver must be linked with the ID code of the transmitter with which it is being paired. Once the link is made, the ID code is stored in the receiver and no further linking is necessary unless the receiver is to be used with another transmitter. (For T/R set, the link is already done at the factory. ) When you purchase another R2004GF, this procedure is necessary; otherwise the receiver will not operate properly. Place the transmitter and the receiver close to each other within one (1) meter 2. When the link is complete, the LED on the receiver changes to solid green. * Please refer to the table below for LED status and receiver condition. No signal reception Receiving signals Receiving signals, but ID is unmatched. Red : On Green: On Green: Blink Link Switch LED WARNING After the linking is done, please cycle receiver power and check if the receiver to be linked is really under the control by the transmitter to be linked. Do not perform the linking procedure with motor's main wire connected or with the engine operating as it may result in serious injury. * If there are many FHSS 4YF 2. 4GHz systems turned on around your receiver, it might not link to your transmitter. In this case, even if the receiver's LED stays solid green, unfortunately the receiver might have established a link to one of the other transmitters. In order to avoid the problem, we strongly recommend you to double-check whether your receiver is controlled by your transmitter by giving stick input and then checking servo response. RECEIVER AND SERVO CONNECTIONS Output Channel 1 2 3 4 B Function Aileron -or-right elevon (for tailless models) Elevator -or-left elevon (for tailless models) Throttle Rudder Receiver on/off switch (red-colored plug) Rudder Servo (CH4) Receiver (Red) Throttle Servo (CH3) Elevator Servo (CH2) Switch Harness Aileron Servo (CH1) Charging Jack (Black) WARNING To Battery NEVER use dry batteries for R2004GF as it may cause difficulties. 9 RADIO INSTALLATION Follow these guidelines to properly mount the servos, receiver and battery. · Make certain the alignment tab on the battery, switch and servo connectors is oriented correctly and "keys" into the corresponding notch in the receiver or connectors before plugging them in. [. . . ] Have an assistant stand by the model and signal what the controls are doing to confirm that they operate correctly. You should be able to walk approximately 10m (33ft) from the model without losing control. Set the transmitter in a safe, yet accessible location so it will be within reach after starting the engine. Be certain the throttle stick is all the way down, then start the engine. [. . . ]
