    PROTECTION OF EYES FROM LASER BEAM DURING SERVICING -1/1 CAUTION This set employs laser. Therefore, be sure to follow carefully the instructions below when servicing. Use of controls or adjustments or performance of proce- dures other than those specified herin may result in WARNING!! hazardous radiation exposure.
  • Page 5: Note On Before Starting Repair

    NOTE ON BEFORE STARTING REPAIR -1/2 1. Forced discharge of electrolytic capacitor of power supply block When repair is going to be attempted in the set that uses relay circuit in the power supply block, electric potential is kept charged across the electrolytic capacitors (C101, 102) even though AC power cord is removed.
  • Page 6 NOTE ON BEFORE STARTING REPAIR -2/2 In such a case, check also if the POWER AMPLIFIER circuit or power supply circuit has any abnormalities or not. 2-2. Regarding reset There are cases that the machine does not work correctly because the MICROCOMPUTER is not reset even though the AC power cord is re-inserted, or the software reset (pressing the STOP key + POWER key) is performed.
