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 procedures other than those specified herin may result in hazardous radiation exposure. WARNING!! WHEN SERVICING, DO NOT APPROACH THE LASER EXIT WITH THE EYE TOO CLOSELY. IN CASE IT IS NECESSARY TO CONFIRM LASER BEAM EMISSION.
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. If repair is attempted in this condition, secondary defect can occur. In order to prevent the secondary trouble, perform the following measures before starting repair work.
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. M IC RO CO M PU TE R 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.
