1. SAFETY & PRECAUTION

1-1. REMEMBER-SAFETY FIRST

WARNING : Always disconnect the unit from the mains supply before dismantling it.

WARNING : Remove your wrist strap before applying power to the reassembled.

equipment to avoid potential shock hazards.

WARNING : The incorrect substitution of electrolytic capacitors may result

in an explosion hazard.

CAUTION : Work on an earth mat and wear a wrist strap and earth lead to prevent

electrostatic damage to components. Once the main board is removed
from the casing it is fairly flexible, so handle it carefully to avoid
damaging the components.

CAUTION : Before you apply mains power to the unit , always ensure

that the voltage rating stated on the rear panel of the unit matches
the mains voltage supply in the country of installation.

CAUTION : Do not spray chemicals on or near the unit.

CAUTION : Replacements for faulty components must be of the correct value

and rating and must be assembled by a competent service engineer,
otherwise safety approvals could be invalidated.

CAUTION : Do not put anything on the top cover and beside of unit for well ventilation.

CAUTION : Do not overload wall outlets, extension cords or convenience receptacles

beyond their capacity, since this can result in fire or electric shock.

CAUTION : Never push objects of any kind into the set through the cabinet slots

as they may touch dangerous voltage point or short out part that could
result in a fire or electric shock.
