Before servicing the pickup assembly be sure to prevent electrostatic-inducer destruction by grounding not only test equipment in use but also yourself. *Electrostatic charge drastically shortens the operating life of the laser diode or possibly results in its destruction. � LD terminals are factory-strapped before shipment to protect LD from electrostatic discharges during transportation. (Fig. 21) After connector insertion, unstrap the LD terminal with a soldering iron. The temperature of the soldering iron tip must be 320� or below (30W) and the unstrapping should be performed quickly. � Don't disassemble the pickup ass'y. � Don't apply shock to the pickup ass'y. � Don't place the assembly in a place subject to excessive dust, heat or moisture. � The LD chip is manufactured from GaAs and GaAlAs, which contains toxic As (Arsenic). Parts removed in servicing should be disposed of with due care.

2-1-2 Objective
Never look directly into the LD or observe the laser beam through another lens or mirror. � Don't touch the objective with fingers. � If objective becomes dirty, playback will deteriorate. To clean the objective, moisten a good cleaning tissue, such as made by KODAK, in isopropyl alcohol and wipe the objective gently. Wipe off and excess fluid with a dry cleaning tissue.
