Dear SHARP Customer

Thank you for your purchase of the Sharp LCD product. To ensure safety and many
years of trouble-free operation of your product, please read the Safety Precautions
carefully before using this product.

Safety Precautions

Page

Electricity is used to perform many useful functions, but it can also cause personal injuries and property
damage if improperly handled. This product has been engineered and manufactured with the highest
priority on safety. However, improper use can result in electric shock and/or fire. In order to prevent
potential danger, please observe the following instructions when installing, operating and cleaning the
product. To ensure your safety and prolong the service life of your LCD product, please read the following
precautions carefully before using the product.

1. Read instructions—All operating instructions must be read and understood before the product is
operated.

2. Keep this manual in a safe place—These safety and operating instructions must be kept in a safe
place for future reference.

3. Observe warnings—All warnings on the product and in the instructions must be observed closely.

4. Follow instructions—All operating instructions must be followed.

5. Cleaning—Unplug the power cord from the AC outlet before cleaning the product. Use a damp
cloth to clean the product. Do not use liquid cleaners or aerosol cleaners.

6. Attachments—Do not use attachments not recommended by the manufacturer. Use of inadequate
attachments can result in accidents.

7. Water and moisture—Do not use the product near water, such as bathtub, washbasin, kitchen sink
and laundry tub, swimming pool and in a wet basement.

8. Stand—Do not place the product on an unstable cart, stand, tripod or table. Placing the product on
an unstable base can cause the product to fall, resulting in serious personal injuries as well as
damage to the product. Use only a cart, stand, tripod, bracket or table recommended by the
manufacturer or sold with the product. When mounting the product on a wall, be sure to follow the
manufacturer’s instructions. Use only the mounting hardware recommended by the manufacturer.

9. When relocating the product placed on a cart, it must be moved with utmost care. Sudden stops,
excessive force and uneven floor surface can cause the product to fall from the
cart.

10.Ventilation—The vents and other openings in the cabinet are designed for ventila­tion. Do not cover or block these vents and openings since insufficient ventilation
can cause overheating and/or shorten the life of the product. Do not place the
product on a bed, sofa, rug or other similar surface, since they can block ventila­tion openings. This product is not designed for built-in installation; do not place
the product in an enclosed place such as a bookcase or rack, unless proper
ventilation is provided or the manufacturer’s instructions are followed.

11.Power source—This product must operate on a power source specified on the specification label.
If you are not sure of the type of power supply used in your home, consult your dealer or local
power company. For units designed to operate on batteries or another power source, refer to the
operating instructions.

12.Power cord protection—The power cords must be routed properly to prevent people from stepping
on them or objects from resting on them. Check the cords at the plugs and product.

13.Regarding AC adapter and power cord
a. If the AC adapter is misplaced or needs to be replaced, obtain the same type of adapter from a

Sharp service center or your dealer.

b. If the product is to be used overseas, contact a Sharp service center or your dealer and obtain a

power cord that complies with the applicable safety regulations of the country in which the
product will be used.

14.The LCD panel used in this product is made of glass. Therefore, it can break when the product is
dropped or applied with impact. Be careful not to be injured by broken glass pieces in case the
LCD panel breaks.

15.Overloading—Do not overload AC outlets or extension cords. Overloading can cause fire or
electric shock.

16.Entering of objects and liquids—Never insert an object into the product through vents or openings.
High voltage flows in the product, and inserting an object can cause electric shock and/or short
internal parts. For the same reason, do not spill water or liquid on the product.

17.Servicing—Do not attempt to service the product yourself. Removing covers can expose you to
high voltage and other dangerous conditions. Request a qualified service person to perform
servicing.

18.Repair—If any of the following conditions occurs, unplug the power cord from the AC outlet, and
request a qualified service person to perform repairs.
a. When the power cord or plug is damaged.
b. When a liquid was spilled on the product or when objects have fallen into the product.
c.When the product has been exposed to rain or water.
d. When the product does not operate properly as described in the operating instructions.

Do not touch the controls other than those described in the operating instructions. Improper
adjustment of controls not described in the instructions can cause damage, which often requires

extensive adjustment work by a qualified technician.
e. When the product has been dropped or damaged.
f. When the product displays an abnormal condition. Any noticeable abnormality in the product

indicates that the product needs servicing.

19.Replacement parts—In case the product needs replacement parts, make sure that the service
person uses replacement parts specified by the manufacturer, or those with the same characteris­tics and performance as the original parts. Use of unauthorized parts can result in fire, electric
shock and/or other danger.

20.Safety checks—Upon completion of service or repair work, request the service technician to
perform safety checks to ensure that the product is in proper operating condition.

21.Wall or ceiling mounting—When mounting the product on a wall or ceiling, be sure to install the
product according to the method recommended by the manufacturer.

22.Heat sources—Keep the product away from heat sources such as radiators, heaters, stoves and
other heat-generating products (including amplifiers).

The LCD panel is a very high technology product with 921,600 thin film transistors, giving you
fine picture details.
Occasionally, a few non-active pixels may appear on the screen as a fixed point of blue, green
or red.
Please note that this does not affect the performance of your product.

RS232C terminal specifications

■When a program is set, the LCD Monitor can be controlled from the computer using the RS232C
terminal. The input signal (computer/video) can be selected, the volume can be adjusted and
various other adjustments and settings can be made, enabling automatic programed playing.

■Attach an RS232C cable cross-type (commercially available) to the supplied Din-D/sub RS232C for
the connections.

This operation system should be used by a person who is accustomed to using computers.

Connections

Connect this unit with the RS232C terminal of the computer.
Send the control commands from the computer via the RS232C terminal.

Mount the cable clamps when connecting cables to the rear terminal section (see page 6).

Note

Communication procedure

Send the control commands from the computer via the RS232C terminal.
The LCD Monitor operates according to the received command and sends a response message to the
computer.
Do not send multiple commands at the same time. Wait until the computer receives the OK response
before sending the next command.

When more than one code is being sent, send each command only after the OK response code for the
previous command from the LCD Monitor is verified.

When using the computer control function of the LCD Monitor, the LCD Monitor operating status
cannot be read to the computer. Therefore, confirm the status by transmitting the display commands
for each adjustment menu and checking the status with the On-screen Display. If the LCD Monitor
receives a command other than a menu display command, it will execute the command without
displaying the On-screen Display.

Commands

Example: The AV input mode set to PAL after switching the display mode to AV1.
