· Another G1X as a receiver (hereinafter referred to as “the receiver”)
· Jumper wires
1. Remove the bottom plate.
2. Connect “IN” terminal of the transmitter and “OUT” terminal of the receiver.
3. Connect “OUT” terminal of the transmitter and “IN” terminal of the receiver.
4. Connect their ground terminals on the top side of the main PCB, using jumper wires (See
below).

- 10 -
6. Press the [BANK UP・TAP] key (SW1) of the receiver, and make sure that the 7 segment
LED lit “rx”. The receiver is ready to receive the data.
7. Press the [Rhythm] key (SW2) of the transmitter and make sure that the 7 segment LED
lit “tx”. The indication flashes on and off at once. And the transmitter starts to send the
data. When sending and receiving finish successfully, and make sure that Transmitter
and Receiver’s both 7 segment LED are displayed same check-sum.
8. Turn the both transmitter and receiver off.
9. Take the wires away and attach the bottom plate.

Recovering the Factory Default
In the factory default condition, the patches of the user area (A0-d9) contain the same settings as the
patches of the preset area (00-39).
Even after overwriting the user patches, their original content can be restored in a single operation
(“All Initialize” function).
If necessary, back up the user’s patch data. Refer to page 9, 10 for details of the back up.
1. Turn the power on while holding the [STORE] key (SW3).
The indication “AL” appears on the display.
2. To carry out the All Initialize function, press the [STORE] key (SW3) once more.
All patch settings are returned to the factory default condition, and the unit switches to
play mode. To cancel All Initialize, press the[RHYTHM] key (SW2) instead of the [STORE] key
(SW3).
