    10. To Supply Power Source Cautions: - It is very dangerous to look at or touch the laser beam. (Laser radiation is invisible.) With the unit turned “on”, laser radiation is emitted from the pickup lens. - Avoid exposure to the lase beam, especially when performing adjustments.
  • Page 50 1. Connect a DC power supply to JK1-5pin and JK1-6pin and . Then adjust the outputs to 10V for 5pin (refer to Fig. 5 and Fig. 6) Fig. 5 Fig. 6 Note: Use only this method when checking the voltage etc.. In case of checking operations, use the system connections to supply power source.
