Thelaserdiodes inthetraverse deck (optical pickup)may break downduetopotential difference
causedbystaticelectricityofclothes or humanbody. / So, becareful ofelectrostaticbreakdown
during repairofthetraverse deck (optical pickup).
4.1. Handling thetraverse deck / (optical pickup)
1. Thetraverse deck (optical pickup)isanextremelyhigh-precision
construction and must notbesubjectedtoimpact, excessive
vibration, orothertypes ofrough handling.
