Service work should be performed only by qualified service technicians who are
thoroughly familiar with all safety checks and servicing guidelines as follows:

(Fire & Shock Hazard)
Before returning the projector to the user, perform
the following safety checks:
1. Inspect lead wires are not pinched between the
the following safety checks:
1. Inspect lead wires are not pinched between the
chassis and other metal parts of the projector.
2. Inspect all protective devices such as non-metallic
control knobs, insulating materials, cabinet backs,
adjustment and compartment covers or shields,
isolation resistor-capacity networks, mechanical
insulators, etc.

3. To be sure that no shock hazard exists, check for
current leakage in the following manner:
»
Plug the AC cord directly into a 120-volt AC outlet,
(Do not use an isolation transformer for this test).

All checks must be repeated with the AC plug
connection reversed. (If necessary, a non-polarized
adapter plug must be used only for the purpose of
completing these checks.)
Any reading of 0.3 volts RMS (this corresponds to
0.2 milliamp. AC.) or more is excessive and indicates
a potential shock hazard which must be corrected
before returning the unit to the owner.

inspection, nor can protection afforded by them be
necessarily increased by using replacement components
rated for higher voltage, wattage, etc.
Replacement parts which have these special safety
characteristics are identified in this manual; electrical
