Preset and user modes

When the monitor receives an input signal, it automatically matches the

signal to one of the factory preset modes stored in the monitorÕs memory to

provide a high quality picture.

For input signals that do not match one of the factory preset modes, the

digital Multiscan technology of this monitor ensures that a clear picture

appears on the screen for any timing in the monitorÕs frequency range

(horizontal: 30 Ð 80 kHz, vertical: 48 Ð 170 Hz). If the picture is adjusted,

the adjustment data is stored as a user mode and automatically recalled

whenever the same input signal is received.

Power saving function

This monitor meets the power-saving guidelines set by VESA, ENERGY

STAR,andNUTEK.Ifnosignalisreceivedbythemonitorfromyour

computer, the monitor will automatically reduce power consumption as

shown below.

* When your computer is in active off mode, MONITOR IS IN POWER

SAVE MODE appears on the screen if you press any button on the

monitor. After a few seconds, the monitor enters the power saving

mode again.

Design and specifications are subject to change without notice.

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 microamperes).

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 bat-

tery-operated AC voltmeter. The “limit” indication 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)

After correcting the original service problem, perform the following safety

checks before releasing the set to the customer:

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

tions. Check the entire board surface for solder splashes and bridges.

2. Check the interboard wiring to ensure that no wires are “pinched” or con-

tact high-wattage resistors.

3. Check that all control knobs, shields, covers, ground straps, and mount-

ing hardware have been replaced. Be absolutely certain that you have

replaced all the insulators.

4. Look for unauthorized replacement parts, particularly transistors, 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 deterio-

ration. Point them out to the customer and recommend their replacement.

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

ment 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 de-

scribed right.

POWER SAVING FUNCTION

This monitor meets the power-saving guidelines set by VESA, TCO 99,

and ENERGY STAR. If no signal is input to the monitor from your

computer, the monitor will automatically reduce power consumption as

shown below.

*1Figures reflect power consumption when no USB compatible

peripherals are connected to the monitor.

*2When your computer enters power saving mode, NO SIGNAL appears

on the screen. After a few seconds, the monitor enters power saving

mode.

*3Deep sleep is power saving mode defined by the Environmental

Protection Agency.
