Connect the monitor power lead to the mains supply, via an isolation transformer, and switch on,
Using the test circuit shown in Fig1-1 measure the AC leakage current between each pole (L and N)
of the supply and all accessible metal parts. The earth leakage current must not exceed 3.5mA
1-2 product safety notice
Many electrical and mechanical parts in this chassis provide special visual safety protection . The
protection afforded by them cannot necessarily be obtained by using replacement components rated
for higher voltage. wattage. etc..
Before replacing any of these components. read the parts list in this manual carefully. The use of
substitute replacement parts which do not have the same safety characteristics as specified in the
parts list may create shock, fire.
X-RAY radiation or other hazards.
1-3 service notes
1) When replacing parts or circuit boards. wrap the wires around terminals before soldering.
2) When replacing a high wattage resistor (more than 1/2w) on a circuit board keep the resistor
about 10mm (1/2 inch) away from circuit board.
3) Keep wires away from high voltage or high temperature components.
4) Keep wires in their original position so as to reduce interference.
