NOTES ON THE RS600 RECEIVER

CHANGING THE SHIFT FROM POSITIVE(+) TO NEGATIVE(-)
6
JR ® has conveniently provided a means to
make the RS600 receiver truly a universal piece
of equipment by providing you, the end user,
with the means to change from the supplied
positive (+) shift normal JR operation to the
optional negative (-) shift operation by moving
a small jumper wire in a block on the PC board.
Please proceed as follows:
1. Remove crystal (if installed) and the end
plate located at the crystal end of the case:
2. On the bottom of the case (with the FCC
sticker) you will find a small tab located
towards the servo wire in/out end of the
receiver. Lift that tab slightly while pulling on
the PC board gently.
3. Place the PC board on the work surface as
shown in the following picture, with the Servo
connectors to the right.

4. Locate block "A" on the PC board, and the
wire that is inserted into block "A". This jumper
wire needs to be moved so it is inserted into
the center hole and the opposite hole.
5. Please note from the drawing below the
proper jumper wire location for positive (+)
shift operation and negative (-) shift operation.
