INSTALLATION
Installation of the Yakuza board must be carefully done to avoid damaging the electronics or wiring harnesses.
1. Remove the grip panel from the right side of the grip frame, exposing the battery and circuit board.
2. Remove the battery and unplug the eye and solenoid harnesses.
3. Remove the 3 mounting screws.
4. Gently pull the stock board out of the frame.
5. Make sure to keep track of the 3 switch contacts.
6. Insert the Yakuza board into the grip frame.
7. Replace the 3 mounting screws, making sure the three switches sit snugly against the rear of the frame.
8. Plug the eye and solenoid harness back into the appropriate sockets.
9. Replace the battery. The positive terminal is towards the front of the frame, as shown by the + and – marks
on the surface of the board.
10. Replace the grip panel.
BOARD OPERATION
Turn on the board by pushing the middle button. The OLED display will show the boot screen, followed by the
main screen with the current fire mode, rate of fire, battery, and eye status visible.
Turn off the board by pressing and holding the middle button for at least 1 second. The OLED display will turn off
to indicate the board has shut down.
The eye system is toggled on and off by pressing and holding the top button. The OLED display will reflect the eye
status.
If used, the eye system cycles the marker as fast as possible. During each shot the eyes watch for the bolt to return,
ending the current firing cycle and starting another as quickly as the pneumatics allow. If the eye system is
continually blocked (e.g. putting your finger in front of the eyes) and is unable to see the bolt return after every shot,
the max rate of fire will be reduced to prevent further chopping, and the OLED display will show an eye
malfunction. Firing the marker with paint and air will utilize the eye system correctly, maximizing the rate of fire.
