2-1 2.0 SAFTETY INSTRUCTIONS GB NL ESD WARNING Alle IC’s en vele andere halfgeleiders zijn gevoelig voor electrostatische ontladingen (ESD). Onzorgvuldig behandelen tijdens reparatie kan de levensduur drastisch doen verminderen. Zorg ervoor dat u tijdens reparatie via een polsband met weerstand verbonden bent met hetzelfde potentiaal als de massa van het apparaat. Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.
2-2 2.1 ESD PROTECTION When the power supply is being turned on, you may not remove this laser cautions label. If it removes, radiation of laser may be received. PREPARATION OF SERVICING Pickup Head consists of a laser diode that is very susceptible to external static electrocity. Although it operates properly after replacement, if it was subject to electrostatic discharge during replacement, its life might be shortened. When replacing, use a conductive mat, soldering iron with ground wire,etc.
2-3 SAFTY NOTICE SAFTY PRECAUTIONS LEAKAGE CURRENT CHECK Plug the AC line cord directly into a 120V AC outlet (do Measure the AC voltage across the 1500 not use an isolation transformer for this check). Use an AC voltmeter, having 5000 per volt or more sensitivity. The test must be conducted with the AC switch on and then repeated with the AC switch off. The AC voltage Connect a 1500 indicated by the meter may not exceed 0.3V.A reading 10W resistor,paralleled by a 0.15uF resistor.
2-4 2.2 SAFETY INSTRUCTIONS Battery Handling Guideline Since the battery is packed in soft package, to ensure its good performance, it’s very important to carefully handle the battery 2.2.1 Soft Aluminium foil The soft aluminum packing foil is very easily damaged by sharp edge parts such as Ni-tabs, pins and needles. • Don’t strike battery with any sharp edge parts • Trim your nail or wear glove before taking battery • Clean worktable to make sure no any sharp particle 2.2.
