Power Saving Function

This monitor meets the power-saving guidelines set by

VESA and

ENERGY STAR, as well as the more stringent

NUTEK .

If the monitor is connected to a computer or video graphics

board that is VESA DPMS (Display Power Management

Signaling) compliant, the monitor will automatically reduce

power consumption in three stages as shown right.

You can set the delay time before the monitor enters the

power saving mode using the OSD. Set the time according

to "Setting the Power Saving Delay Time" on page 1-7.

Power consumption of the monitor only. The figures in

parentheses are power consumption of the monitor including

the AC adapter.

** "Sleep" and "deep sleep" are power saving modes defined by

the Environmental Protection Agency.

*** When your computer enters the power saving mode, the input

signal is cut and NO INPUT SIGNAL appears on the screen.

After the time set in "Changing the Power Saving Delay Time"

(page 1-7) has elapsed, the monitor enters the power saving

mode.

LEAKAGE TEST

The AC leakage from any exposed metal part to earth ground

and from all exposed metal parts to any exposed metal part hav-

ing a return to chassis, must not exceed 0.5 mA (500

microampers).

Leakage current can be measured by any one of three methods.

1. A commercial leakage tester, such as the Simpson 229 or

RCA WT-540A. Follow the manufacturers' instructions to

use these instruments.

2. A battery-operated AC milliammeter. The Data Precision

245 digital multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of a

VOM or battery-operated AC voltmeter. The "limit" indica-

tion is 0.75 V, so analog meters must have an accurate low-

voltage scale. The Simpson 250 and Sanwa SH-63Trd are

examples of a passive VOMs that are suitable. Nearly all

battery operated digital multimeters that have a 2 V AC

range are suitable. (See Fig. A)

WARNING!!

NEVER TURN ON THE POWER IN A CONDITION IN

WHICH THE DEGAUSS COIL HAS BEEN REMOVED.

SÉCURITÉ!!

LES COMPOSANTS IDENTIFIÉS PAR UNE TRAME ET

¡ SONT CRITIQUES POUR LA SÉCURITÉ.

NE LES REMPLACER QUE PAR UNE PIÈCE PORTANT LE

NUMÉRO SPECIFIÉ. LES RÉGLAGES DE CIRCUIT DONT

After correcting the original service problem, perform the fol-

lowing safety checks before releasing the set to the customer:

1. Check the area of your repair for unsoldered or poorly-sol-

dered connections. Check the entire board surface for solder

splashes and bridges.

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.

4. Look for unauthorized replacement parts, particularly tran-

sistors, that were installed during a previous repair. Point

them out to the customer and recommend their replacement.

5. Look for parts which, though functioning, show obvious

signs of deterioration. Point them out to the customer and

recommend their replacement.

6. Check the line cords for cracks and abrasion. Recommend

the replacement of any such line cord to the customer.

7. Check the B+ and HV to see if they are specified values.

Make sure your instruments are accurate; be suspicious of

your HV meter if sets always have low HV.

8. Check the antenna terminals, metal trim, "metallized"

knobs, screws, and all other exposed metal parts for AC

Leakage. Check leakage as described below.
