[. . . ] Futaba DIGITAL PROPORTIONAL RADIO CONTROL PCM1024H PULSE CODE MODULATION SYSTEM D60914 Thank you for purchasing a FUTABA digital proportional radio control set Please read this manual carefully before using your set The last page of this manual is a three-part foldout Refer to this foldout when reading the manual. TABLE OF CONTENTS FEATURES . 32 RUDDER MIXING (ROTOR DIRECTION, REVOLUTION MIX, ACCELERATION MIX, RUDDER OFFSET) . 57 WARNING: The FUTABA PCM1024H system has numerous operating features and is designed for serious and experienced radio control hobbyists. Newcomers to the hobby should seek advice and assistance in operating this set. [. . . ] When a Back Up error occurs, the back-up lithium battery is probably dead, or there is trouble in the system. The back up lithium battery life depends on the usage state, but is about 5 years. SYSTEM PROGRAMMING Press the EDIT program key of the standard screen. Reversing Fail Safe Adjustable Travel Volume Dual Rate Adjustable Function Rate End (Returns to preceding screen) System functions are programmed and adjusted by using the LCD display screen, the five DATA INPUT (Program) keys, and the four CURSOR keys. Pressing the (EDIT) program key of the standard screen will display the EDIT or "Menu" screen. The cursor keys can be and used to move the cursor bar to Line 1, 2, or 3 of the screen. The program keys are used to select the desired programminq screen to be displayed. NOTE: At all times, pressing the program key will return the display to the next previous screen. To return to the standard screen, just keep pressing the key. [13] ADJUSTMENTS AND FLIGHT TECHNIQUES REVERSE Servo Reversing This function is used to change the direction of servo operation in relation to control stick or /ever movement. Setting Method 1) Select the EDIT screen, the select the REVERSE screen by pressing the program key. 3) Select NORMAL or REVERSE operation by pressing the or program key. 4) Return to the EDIT screen by pressing the program key. FAIL SAFE Fail Safe Fail Safe and Hold Functions The HOLD (Hold) and F/S (Failsafe) functions are designed to allow the aircraft or helicopter to "fly through" a momentary loss of signal or very strong interference, rather than experiencing the familiar "glitch" as the servos react violently to the unwanted signal. These functions cannot be expected to prevent a crash however, if the normal signal interruption is of sufficient duration. The HOLD function stops the servo at the position held just before the normal signal is lost. When a normal signal is again received, the Hold function is released. The FAILSAFE function will move a servo to neutral or a pre-set position when the normal signal is interrupted for 1 second or longer (The system will remain in HOLD for the first 1 second of signal loss). BFS (Battery Fail Safe) Function The BFS function moves the throttle (CH3) servo to the pre-set Fail Safe position when the airborne power supply is nearly exhausted. If no Fail Safe position has been set, the throttle servo will move to medium slow (neutral). BFS can be released by lowering the throttle Stick past the release point (adjustable), or with the CH9 switch. At the end of 30 seconds, BFS will re-engage and the throttle will again move to the Fail Safe position. Whenever BFS engages, land the aircraft as quickly as possible and recharge or replace the Nicd battery pack. [14] Fail Safe and Hold General Instructions Fail Safe · F/S or HOLD can be selected for each channel (1 to 8). ·Channels selected for HOLD will remain in HOLD until a normal signal resumes. Those selected for F/S will move to their pre-set positions after 1 second of signal interruption. · F/S SET simultaneously stores the desired Fail Safe position in the transmitter memory and sends it to the receiver. ·The F/S data is automatically sent to the receiver when the transmitter is first turned ON and at one minute intervals as long as the transmitter is left on. · Only the Throttle channel (CH3) can be set for Battery Fail Safe. [. . . ] The slave channel of the mixing number displayed in the "mas" column, then. becomes a Master channel on the mixing circuit line that it is displayed and the two circuits are connected. 1) Move the cursor to the "slv" position with the or cursor key. 1) is set to AIL. [24] and 1) Method are displayed when the cursor is in the "mas" position. are displayed when the cursor is in the "slv" position. Displayed when cursor is in "mas" position. Indicates that Master channel is "slaved" to another circuit. 2) To activate XON or YON mixing, press the or key, The character will appear next to the appropriate channel on the left side of the screen to indicate that or has been set. ·Combinations allow more efficient use of the number of mixing circuits.
