OPERATING GUIDE

■POWER SOURCE
This colour display is designed to operate on 220/240 volts 50 Hz, AC. Insert the
power cord plug into a220/240 volts 50 Hz safety grounded outlet.
DO NOT CONNECT THE DISPLAY TO OTHER THAN THE SPECI-
FIED VOLTAGE.
Never remove the back cover of the display as this can expose you to very high
voltage and other hazards. If the display does not operate properly, unplug the
display and call your dealer.
NOTES: 1. This colour display is equipped with athree-wire plug. This plug will
only fit into agrounded power outlet. This is asafety feature, do not
defeat the safety purpose of the grounded plug.
2. If the power cord or plug is damaged or frayed, replace it.
3. Do not overload wall outlets or extension cords as this can result in
fire or electric shock.
WARNING:
TO PREVENT SHOCK OR FIRE HAZARD, DO NOT EXPOSE THIS
DISPLAY TO RAIN OR MOISTURE.

INTRODUCTION
The Multi 560 (CM1473ME) from HITACHI is ahigh resolution colour display monitor
that automatically adjust to horizontal scanning frequencies of graphics boards from
15.5 kHz to 35 kHz and vertical scanning frequencies from 50 Hz to 80 Hz.
The Multi 560 gives IBM Personal System/2, PC, PC/XT PC/AT and Compatibles users
quality graphics and text displays.
■High resolution up to 800 dots x 560 lines from 14-inch large screen.
●The Multi 560 automatically adjust to all horizontal frequencies between 15.5 kHz to
35 kHz and all vertical frequencies between 50 Hz to 80 Hz.
Ergonomically designed cabinet with tilt and swivel base.
The Multi 560 offers both TTL and Analogue inputs.
Selection between TTL and Analogue can be controlled from the front panel.

Cautions when using the Multi 560
WARNINGS
NEVER REMOVE THE BACK COVER
Removal of the back cover shall be done only by qualified personnel.
USE CORRECT VOLTAGE
Use only the rated voltage supply. When the power voltage is extremely high or low, -”
it may cause trouble or it may not give optimum performance.
DO NOT USE AT WRONG PLACE
To prevent shock or tire hazard, DO NOT expose the Multi 560 display to rain or mois-
ture.
This unit is designed to be used in offices or homes. DO NOT subject the unit to vibra-
tions, dust or corrosive gases.
KEEP IN AWELL VENTILATED PLACE
Ventilation holes are provided on the cabinet to prevent the temperature from rising.
DO NOT cover the unit or place anything on top of the unit.
AVOID HEAT
Avoid placing the unit in direct sunshine or near heating appliance.
BE CAREFUL OF MAGNETIC FIELDS
Do not place amagnet, speaker systems, printers or floppy disk drives which generate
magnetism near the unit. Amagnetic field may cause blurred colours or distortion of the
displayed pattern. .-

to turn the power OFF.
@POWER ON INDICATOR
Agreen light comes on when the power is ON.
@HORIZONTAL PHASE CONTROL
This control adjust the horizontal position of the display data.
At the extreme sides of control the display data may wrap around depending the signal
timing. Adjust to avoid this.
@BRIGHTNESS CONTROL
While receiving analogue signals, this controls background raster brightness. Adjust the
background to the position where the background is just diminished.
While receiving TTL signals, this controls the brightness level of the whole signal. Adjust
‘-
this to obtain required brightness.
@CONTRAST CONTROL
+
While receiving analogue signals, this controls the brightness of data (including background
colour). Adjust this to obtain the required brightness.
While receiving TTL signal this controls the brightness differences between low and high
intensity colours (16 colour mode) or between primary and secondary colours (64 colour
mode).
@TEXT SWITCH
Pressing this control switches the screen from full colour to single amber colour while
receiving TTL signal input.
Press it again changes screen back to full colour.

Q!E%$TTL/ANALoGuEs~TcH
By pressing this switch, input signals can be selected between analogue and TTL.
* Avoid supplying both analogue and TTL signals at the same time since this may cause
interferences between the signals (cross-talk). Both connectors can be connected at the
same time.
QHORIZONTAL SIZE CONTROL
This controls the horizontal size.
_VERTICAL SIZE CONTROL
This controls the vertical size.
eVERTICAL CENTERING CONTROL
This controls the vertical position of the data display. /
-16/64 COLOUR SELECT
When pressed in, the 64 colour mode is selected.
When set out, the 16 colour mode is selected.
When the AUTO mode is selected by the switch @.This colour select does not work.
Instead, the monitor select 16 or 64 colour as standard EGA monitor.
@@l?@ AuTo/MANuAL SELECT
When it is pressed out, the auto mode is selected. When the auto mode is selected, the
Multi 560 automatically adjust to the IBM graphics board requirements including Per-
sonal system/2.
When set in, the manual mode is selected.
The display size is proportional to the signal. When the signal timing is differ from afried
size, size controls 8and 9should be adjusted to obtain the required size. These controls
may not be capable for complete controls depending on the signal supplied.
_TTL INPUT TERMINAL
Connect TTL output of the computer.

How to Remove or Install aTdt/Swivel Stand
You can set the colour monitor to the desired angle with the tilt stand supplied.
CAUTION –This colour monitor may be used only with HITACHI exclusive tilt stand.
Use with other tilt stands may result in instability causing possible injury.
If you change the direction of monitor or operating condition, may cause impeTfect
colour uniformity because of the influence of earth ma~etism. This is not failure.
If you are worried about it, turn the power off and on again at an interval of 20-30
minutes or more after the power on to activate the internal auto degaussing.
(1) Install the tilt stand at the bottom of
the colour monitor. (2) Fix the stand at 2positions using
screws.
