NOTICE
This equipment has been tested and found to comply with the limits for a
Class
B
digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference
in a residential installation. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
-
Reorient or relocate the receiving antenna.
-
Increase the separation between the equipment and receiver.
-
Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
-
Consult the dealer or an experienced radio/TV technician for help.

Warning notes indicate any condition or practice, which if not
strictly observed, could result in personal injury or possible
death.
CAUTION
: Possible damage to equipment.
Caution notes indicate any condition or practice, which if not
strictly observed or remedied, could result in damage or
destruction of the equipment.
NOTE :
Notes indicate an area or subject of special merit,
emphasizing either the monitor’s capabilities or common
errors in operation or maintenance.
1. Read and understand all of these instructions before installing this
monitor.
2. Save this manual for later use.
3. Follow all warnings, cautions and instructions marked on the monitor.
Leaving the unit connected to mains while cleaning or servicing,
may cause an electric shock.
Unplug the monitor from the outlet before you clean or service the
monitor.
Spray and moisture,
may cause an electric shock or hardware damage.
DO NOT use the monitor in such a place where it is likely to be effected by
spray of fluids or moisture.
Unstable positions,
may cause serious damage to the monitor or personal
danger, if it falls.
DO NOT put the monitor on an unstable cart, stand, or table.
Using wrong plugs,
may cause a risk of shock.
Use a
3-wire
grounding type plug having a third (grounding) pin.
This is a safety feature.
If you are unable to insert the plug into the outlet, contact your
electrician to replace your obsolete outlet.

WARNING
Blockage of ventilation slots,
may cause a risk of fire or electric
shock.
DO NOT push any object into the monitor through cabinet slots, because
it may touch dangerous voltage points or short out parts.
DO NOT spill any liquid into the monitor.
DO NOT insert any object into
the
monitor.
A. The slots and openings must not be blocked or covered.
B.
The monitor must never be placed near or over a radiator or heat
register.
C. The monitor should be placed in a built-in installation unless proper
ventilation is provided.
Maintenance by unqualified personnel, may
cause an electric shock or
source of damage.
DO NOT attempt to service the monitor by yourself, because opening or
removing covers may expose you to dangerous voltage points or other
risks. Refer all servicing to “Qualified” service personnel.
Fuse replacement by unqualified personnel, may
cause you an electric
shock or hardware damage.
Only trained service personnel should change the fuse. To avoid fire
hazard, use only the fuse specified and which is identical in type, voltage
rating and current rating.
Action if a fault occurs.
Beware, as a fault can cause electric shock or injury.
Unplug the monitor from the power outlet and contact qualified service
personnel if
the
following conditions occur:
A. The power cord or plug is damaged or frayed.
B.
Liquid has been spilled into
the
monitor.
C. The monitor has been exposed to rain or water.
D. The monitor does not operate normally when the operating
instructions are followed. Adjust only those controls that are covered
by this manual since improper adjustment of other controls may result
in damage and will often require extensive work by a qualified
technician to restore the monitor to normal operation.
E.
The monitor has been dropped or the cabinet has been damaged.
F. The monitor exhibits a distinct change in performance, or indicates
a need for service.
Using unauthorized power source,
may cause a risk of shock or serious
damage to the monitor.
The monitor should be operated by the type of power source indicated on
the marking label near the input connector.
If you are not sure of the type of power available, consult your dealer or
local power company.

WARNING
WARNING
WARNING
CAUTION
NOTE
Improper cabling,
may cause injury or a risk of shock.
DO NOT allow anything to rest on the power cord.
DO NOT locate the monitor where persons will walk on the cord.
When routing cable, try to make rounded bends rather than sharp ones
that can kink the cable.
Using extension cord,
may cause a risk of fire or electrical shock.
If an extension
cord
is used with this monitor, make sure that the total of
the ampere ratings on the loads plugged into the extension cord does not
exceed the extension cord ampere rating.
Connecting unspecified input signal (voltage and horizontal
frequency),
may cause serious damage to the monitor.
Confirm the input signal voltage and horizontal frequency before you
connect the video cable to the monitor.
Solvents,
may cause damage to the cabinet.
DO NOT use liquid cleaners or aerosol cleaners directly on the surface of
the cabinet.
Wet a damp cloth with cleaner and apply it to the cabinet.
Ergonomics for User and Manufacturer
A.
For ergonomical reasons it is recommended not to use the primary
color blue on dark background
(
bad visibility, strain for eyes because
of low character contrast.)
B.
An A/R (Anti-Reflection) panel on the CRT reduces eye strain on the
end-user. Be careful of the following items.
1. Do not touch the screen of the CRT, because soiling and fingerprints
reduce legibility and the effectiveness of anti-reflection treatment.
2. Clean the surface of the CRT according to the procedure 2.1 and 2.2
when the surface has soiling or fingerprints.
2.1 Clean the surface of the CRT with a cleaning solution.
2.2 Remove the cleaner by using a damp cloth and wipe the surface
with a soft, dry cloth.

DATA
LOCKING
AND
UNLOCKING
New adjustment data can be stored in the memory of the monitor by
pressing the STORE button. If, however, improper data is accidentally
stored there, the previously stored data will be lost.
This is because only one set of data can be stored with one timing signal.
To prevent such an accident, you can lock new adjustment data after
storing it.
(1)
Protection of Data (Locking)
After storing the adjustment data, you can lock it by holding down the
SELECT button and pressing the STORE button.
(2)
Release of Locked Data (Unlocking)
You can unlock the locked data by holding down the SELECT button
and pressing the RECALL button. Adjustment mode is automatically
set when the data is unlocked. To go back to the normal operation
mode, press the STORE button.

The
monitor
has
four
preset
data
areas
in

3.4
POWER
SAVE
CAPABILITY
The HM-4721-D/ HM-4787-D color monitor has a power save capability
that identifies particular input signals from a microcomputer and saves
power consumption accordingly.
There are four states of power supply:
1. On:
The monitor is operating and consuming the rated power.
2.
Standby:
The monitor is automatically controlled depending on the states
input signals. In this state, the monitor consumes about 110 W.
3.
Suspend: The monitor is automatically controlled depending on the states
input signals. In this state, the monitor consumes 30 W or less.
4. off:
There are three substates:
Offi:
The monitor is automatically controlled depending on the states
input signals. In this substate, the monitor consumes 8 W or
less.
off2:
The front POWER switch is turned
off.
In this substate, the
monitor consumes 8 W or less.
Off 3: The main POWER switch is turned off. In this substate, the
monitor consumes no power.
While the monitor is in standby, suspend, or off state (the indicator is orange
or off), nothing is displayed on the screen.
Standby, suspend, and off 1 are controlled by the input signals from the
computer system or signal generator connected to the monitor. See also the
instruction manuals for these hardware units. Input signal states are shown
in Table 3.2. The table conforms to the DPMS* standard of VESA**.
