[. . . ] INSTRUCTION MANUAL Part #1785 STEP 1 GT7 BASIC SET-UP CHANGING INPUT HARNESS STEP 2 GT7 BASIC SET-UP MOUNTING INSTRUCTIONS PROGRAMMABLE RACING ESC The GT7 speed control comes with the industry standard connector on a user-replaceable input harness. This connector works with all major radio brands. However, with some older style receivers, the wiring sequence in the plastic connector must be changed. This is an important step, because the receiver electronics may be damaged if the sequence is incorrect. 1. [. . . ] RELEASE SPEED CONTROL'S SET BUTTON Blue status LED will flash. The number of times the LED flashes indicates the Minimum Brake selection (1 of 7). PRESS & RELEASE SET BUTTON TO CHANGE SELECTION Each press will change to the next consecutive Minimum Brake value. (After value #7, the sequence begins again at value #1) 6. WAIT FOR SPEED CONTROL TO EXIT PROGRAMMING When SET button is not pressed for about 3 seconds, the selected Minimum Brake value is loaded into memory. The blue status LED will then flash a few times rapidly, then the status LEDs will come on, one at a time, scrolling from topto-bottom indicating that you are exiting programming. The red status LED will then turn on solid, indicating that the speed control is at neutral and ready to go. G. Set MECHANICAL TRIGGER THROW ADJUSTMENT to position with 2/3 throttle and 1/3 brake throw. [adjusts trigger throw on mechanical/analog pistol-grip transmitters] RECEIVER BATTERY PACK If using an external receiver battery pack with the GT7: 1. Plug an external 5 cell (1. 2VDC/cell) receiver battery pack into the battery slot of the receiver. Leave the GT7's ON/OFF switch in the OFF position. Use receiver battery pack's ON/OFF switch to turn the system power on and off­­Do not use the GT7's switch. Checking That Transmitter Has Adequate Throw With transmitter ON, GT7 OFF & connected to receiver & battery: 1. PRESS & HOLD SPEED CONTROL'S SET BUTTON 2.
