POWER SAVING FUNCTION
This monitor meets the power saving guidelines set
by the EPA Energy Star Program as well as the more
stringent TC092 guidelines (NUTEK). It is capable of
reduced power consumption when used with a com-
puter equipped with Display Power Management Sig-
naling (DPMS). By sensing the absence of the sync
signal coming from the computer, it will reduce the
power consumption as follows:

The Power Saving function will automati-

if the power switch is turned on without
any video signal input. Once the horizon-
tal and vertical syncs are sensed, the moni-
tor will automatically return to its Normal
operation state.

LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground
and from all exposed metal parts to any exposed metal part having
a return to chassis, must not exceed 0.5 mA (500 microampere).
Leakage current can be measured by any one of three methods.

2. Check the interboard wiring to ensure that no wires
are “pinched” or contact high-wattage resistors.
3. Check that all control knobs, shields, covers, ground
straps, and mounting hardware have been replaced.
Be absolutely certain that you have replaced all the
insulators.

3. Measuring the voltage drop across a resistor by means of
a VOM or battery-operated AC voltmeter. The "limit"
indication is 0.75 V, so analog meters must have an accurate
low voltage scale. The Simpson's 250 and Sanwa
SH-63Trd are examples of passive VOMs that are suitable.
