Jumpering the charging circuit diode in
Futaba Conquest transmitters

This modification, when properly done, will not affect the operation of your
transmitter, nor will it void your warranty. However, do not attempt this procedure

unless you are comfortable with soldering electronic equipment!

1. Unscrew and remove the antenna.

2. Remove the back cover of the transmitter.

Do this ONLY with

5 or 6 channel radios

3. Unplug the antenna wire (black and white twisted pair) from the main circuit board.

Remove 3 black screws holding the mian circuit board, and fold the board to the right.

4. Locate the small printed circuit board mounted on the back of the ON/OFF switch. For safety, unplug the

battery connector from this board (pull straight out).

5. Solder a small jumper wire across the diode, as indicated. (The diode is located on the other side of the board,

where you can't see it.)

6. Plug in the battery connector, and test the installation by plugging you SIRIUS CHARGE into the transmitter

charging jack. The Green TX LED should light on SIRIUS CHARGE.

Do this ONLY with

5 or 6 channel radios

7. Replace the main circuit board with the 3 black screws. Plug in the antenna wire (black

and white twisted pair).

8. Replace the antenna and the transmitter back, being careful not to pinch any wires.
