(MEMO) 

• Using this monitor’s screen-size switching or dual-screen display functions to compress or expand the screen for commercial 

or public viewing in establishments like cafes or hotels may infringe on the rights of the creators, as protected by Copyright 

Law, so please be careful. 

• When dual-screen display is selected, the screen size cannot be changed. 

• The appearance of the original video may change if you select a screen size with a different aspect ratio than the original 

image (e.g. TV broadcast or video input from external equipment). 

• When an ordinary non-wide image (4:3) is viewed with the whole screen using the screen-size switching function of this 

monitor, the edge of the image may be lost or appear distorted. If you wish to respect the creator’s intentions, set the screen 

size to “NORMAL”. 

• When playing commercial software, parts of the image (like subtitles) may be cropped. In this case select the optimal screen 

size using the screen-size switching function of this monitor. With some software, there may be noise or distortion at the 

edges of the screen. This is due to the characteristics of the software, and is not a malfunction. 

• Depending on the original image size, black bands may remain at the edges of the screen.

  INSTALLATION, ADJUSTMENT, SETTING  2 - 1 

Chapter 2  INSTALLATION, ADJUSTMENT, SETTING 

 

1. INSTALLATION                                                                       

•  This product is for use indoors. 
•  A mounting bracket compliant with VESA specifications is 

required. 

•  Since the monitor is heavy, consult your dealer before 

installing, removing or moving the monitor. 

•  Mounting the monitor on the wall requires special expertise 

and the work must be performed by an authorized SHARP

 

dealer. You should never attempt to perform any of this

   

work yourself. Our company will bear no responsibility

       

for accidents or injuries caused by improper mounting or

 

mishandling. 

•  Use the monitor with the surface perpendicular to a level 

surface. If necessary, the monitor may be tilted up to 20

 

degrees upward. 

•  When moving the monitor, be sure to hold it with the   

handles and the unit bottom. Do not grasp the screen or

     

tray. This may cause product damage, failure, or injury. 

•  This monitor should be used at an ambient temperature 

between 41°F (5°C) and 95°F (35°C). Provide enough

   

space around the monitor to prevent heat from

   

accumulating inside. 

 

 

 

 

 

 

 

 

 

 

•

If it is difficult to provide sufficient space for any reason     

such as the installation of the monitor inside a housing, or     

if the ambient temperature may be outside of the range       

of 41°F (5°C) to 95°F (35°C), install a fan or take other   

measures to keep the ambient temperature within the 

required range. 

•

Temperature condition may change when using the monitor 

together with the optional equipments recommended by 

SHARP. In such cases, please check the temperature 

condition specified by the optional equipments. 

•

Do not block any ventilation openings. If the temperature  inside 

the monitor rises, this could lead to a malfunction. 

•

  Do not place the monitor on a device which generates heat. 

 

•

  Do not use the product in locations where the unit is exposed   

to direct sunlight or other strong light. Since this 

product operates with infrared rays, such light may cause a 

malfunction.  

 

 

•

 When installing, removing or moving the monitor, ensure that 

this is carried out by at least 4 people. 

•

  Be sure to use a wall-mount bracket designed or designated for 

mounting the monitor. 

•

 This monitor is designed to be installed on a concrete wall or 

pillar. Reinforced work might be necessary for some materials 

such as plaster / thin plastic board / wood before starting 

installation.                                                                                       

This monitor and bracket must be installed on a wall which can 

endure at least 4 times or more the weight of the monitor.              

Install by the most suitable method for the material and the 

structure. 

•

  To attach a VESA-compliant mounting bracket, use M6 screws 

that are 5/16 inch (8 mm) to 3/8 inch (10 mm) longer than the 

thickness of the mounting bracket. 

•

  Do not use an impact driver. 

•

 After mounting, please carefully ensure the monitor is secure, 

and not able to come loose from the wall or mount. 

•

 Do not use any screw holes other than VESA holes for 

installation.

(Caution) 

•

  Be sure to turn off the main power switch and disconnect the plug from the power outlet before connecting/disconnecting cables. Also, 

read the manual of the equipment to be connected. 

•

  Be careful not to confuse the input terminal with the output terminal when connecting cables. Accidentally reversing cables connected to 

the input and output terminals may cause malfunctions and the other problems. 

•

  Do not use any cable that has a damaged or deformed terminal. Using such cables may cause malfunctions.
