3-3. CABLE CLAMP
Use the supplied cable clamp to secure the cables connected to the ter-
minals.
Caution: When adjusting the viewing angle, cables may be pulled.
Therefore, ensure that the cables have sufficient slack.
3-4. USING HEADPHONES
(COMMERCIALLY AVAILABLE)
You can connect headphones (commercially available) to the monitor.
Note: When the headphones are connected, no sound can be heard
from the monitor speakers.
3-5. ANGLE ADJUSTMENT
Adjust to an easy to view angle.
Caution: • Be sure to hold both sides of the monitor when adjusting the
viewing angle. The LCD panel used in this monitor is made of
glass. Pressure from hands on the LCD panel could cause
damage.
• Be careful not to allow your fingers to be pinched.
3-6. USING THE REMOTE CONTROL
Use the remote control by pointing it towards the remote sensor window
on the monitor. Objects between the remote control and sensor window
may prevent proper operation.
Cautions regarding use of remote control
•  Do not expose the remote control to shock. In addition, do not expose
the remote control to liquid, and do not place in an area with high
humidity.
• Do not install or place the remote control under direct sunlight. The
heat may deform the unit.
• The remote control may not work properly if the remote sensor win-
dow of the monitor is under direct sunlight or strong lighting. In such
case, change the angle of the lighting or monitor, or operate the
remote control closer to the remote sensor window.
•  Do not use the remote control simultaneously with remote controls of
other equipments.
3-7. BATTERIES FOR THE REMOTE CONTROL
Before using the monitor for the first time, install two R-03 ("AAA" size,
UM/SUM-4) batteries (supplied).
When the batteries become depleted and the remote control fails to
operate, replace the batteries with new R-03 ("AAA" size, UM/SUM-4)
batteries.
1. Open the battery cover.
Slide the cover while pressing the (V) part.
2. Insert two R-03 ("AAA" size, UM/SUM-4) batteries.
Position the positive and negative ends of the batteries as indicated
in the compartment.

3.
Close the battery cover.
Engage the claw on the cover into the battery housing and slide shut.
Caution:
Improper use of batteries can result in chemical leakage and/or
explosion. Be sure to follow the instructions below.
•  Place batteries with their terminals corresponding to the (+) and (-)
indications.
•  Different types of batteries have different characteristics. Do not
mix batteries of different types.
•  Do not mix old and new batteries. Mixing old and new batteries can
shorten the life of new battery and/or cause the old battery to leak
chemicals.
•  Remove batteries when they become weak. 
Chemicals that leak from batteries can cause a rash. If chemical
leakage is found, wipe with a cloth.
•  The batteries supplied with the product may have a shorter life
expectancy due to storage conditions.
•  If the remote control will not be used for an extended period of time,
remove the batteries from the remote control.

CHAPTER 2. CONNECTION, ADJUSTMENT, OPERATION, AND FUNCTIONS
1-1. Connecting the monitor to a computer
Caution • When connecting, ensure that the monitor and all the equip-
ment you are connecting to it are switched off.
•  Be careful not to over bend the cable or add extension cords
as this could lead to a malfunction.
•  When using the monitor for the first time or after having
changed the system settings during use, perform an auto-
matic screen adjustment.
Note: • Depending on the computer or OS, you may have to install the
set-up information for the monitor.
• When connecting to a notebook and the notebook compute’s
screen is set so that it is displaying at the same time, the MS-
DOS screen may not be able to display properly. In this case,
change the settings so that only the monitor is displaying.
If connecting to a D-sub15 pin 2 row Apple Power Macintosh, attach a 
Macintosh conversion adapter (commercially available) to the analog 
signal cable.
1-2. Antenna connection
Caution: When connecting, ensure that the monitor is switched off.
To enjoy a clearer picture, we recommend that you use an outdoor
