It is recommended that the unit be operated from a suitable DC supply or batteries during initial check-out pro- cedures. (2)Leakage Current Check/Resistance Check
6、 Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 0.5 milliamp, or if the resistance from chassis to either side of the power cord is less than 240 k ohms, the unit is defec- tiv

Handling the Laser Pickup In case of repair or replacement of the Laser Pickup, pay attention to the following handling instructi
14、ons since the la- ser diode in the Laser Pickup is not resistant to static elec- tricity. (1)Grounding When you repair a Laser Pickup, first ground the hu- man body, as well as the measuring instruments and other tools (with particular caution to soldering iron). Whats more, your workbench and floor
15、 should desir- ably be grounded using conductive sheet or copper plate. See Fig. 1.2. NOTE: Be careful so as not to let your clothes touch the Laser Pickup, as static electricity on the clothes will not be released even if your body is grounded. THIS COMPACT DISC PLAYER IS CLASSIFIED AS A CLASS 1 LA
16、SER PRODUCT. THE CLASS 1 LASER PRODUCT LABEL IS LOCATED ON THE REAR EXTERIOR. CLASS 1 LASER PRODUCT (2)Discharge of Electricity Be sure to discharge electricity from objects brought into contact with the Laser Pickup (i.e., soldering iron, tweezers, probes, volt-ohm-meter probes, etc.) before starti
17、ng work by contacting them with the body chassis. Besides, never touch the Laser Pickup while power is applied. (3)Soldering Iron to be Used The soldering iron for use in repair work should be: (1) a ceramic soldering iron, (2) a soldering iron with its metal part grounded, or (3) a soldering iron w
18、hose insulation re- sistance after five minutes of power application is 10 M-ohm or more at 500 VDC. Soldering should be completed promptly, at a soldering iron temperature of 320 max (39 W). A soldering iron heated above this temperature can break down the laser diode. Fig. 1.2 Handling the Laser P
