Laser Warning
This equipment uses a visible red laser. Prevent direct exposure to the beam from the laser.
1Do Step 1 - Step 8 of the GALVO ROTATION procedure.
2Remove the REAR PANEL.
3On the GALVO BOARD, use the DVM TL-3386 set to V DC and connect the (+) end of
the DVM to TP13 and the (-) end of the DVM to TP1.
4Is the GALVO BOARD new?
Yes No
Adjust R2 until the voltage on the
DVM is 10 ± 0.02 V DC. Check that the voltage on the DVM is between 8.2 V DC and 11.9 V DC.
