Safety precautions and maintenance
WARNING: Use of controls, adjustments or procedures other than those specied in this documentation may result in exposure to
shock, electrical hazards and/or mechanical hazards.
Read and follow these instructions when connecting and using your display:
Operation:
• Keep the display out of direct sunlight and away from stoves or any other heat sources.
• Remove any object that could fall into ventilation holes or prevent proper cooling of the display’s electronics.
• Do not block the ventilation holes on the cabinet.
• When positioning the display, make sure the power plug and outlet are easily accessible.
• When turning off the display by detaching the power cord, wait 6 seconds before re-attaching the power cord for normal operation.
• Ensure the use of an approved power cord provided by OTS at all times. If your power cord is missing, please contact your local service center.
• Do not subject the display to severe vibration or high impact conditions during operation.
• Do not knock or drop the display during operation or transportation.
• The eye bolt is for usage in short-time maintenance and installation. We suggest not to use the eye bolt for more than 1 hour. Prolong usage is
prohibited. Please keep a clear safety area under the display while using the eye bolt.
Maintenance:
• To protect your display from possible damage, do not put excessive pressure on the LCD panel. When moving your display, grasp the frame to lift; do
not lift the display by placing your hand or ngers on the LCD panel.
• Unplug the display if you are not going to use it for an extensive period of time.
• Unplug the display if you need to clean it with a slightly damp cloth. The screen may be wiped with a dry cloth when the power is off. However, never
use organic solvent, such as, alcohol, or ammonia-based liquids to clean your display.
• To avoid the risk of shock or permanent damage to the set, do not expose the display to dust, rain, water or an excessively moist environment.
• If your display becomes wet, wipe it with dry cloth as soon as possible.
• If a foreign substance or water gets in your display, turn the power off immediately and disconnect the power cord. Then remove the foreign substance
or water, and send the unit to the maintenance center.
• Do not store or use the display in locations exposed to heat, direct sunlight or extreme cold.
• In order to maintain the best performance of your display and ensure a longer lifetime, we strongly recommend using the display in a location that falls
within the following temperature and humidity ranges.
- Temperature: 5°C-40°C (41°F-104°F)
- Humidity: 20-80% RH
IMPORTANT: Always activate a moving screen saver program when you leave your display unattended. Always activate a periodic screen refresh
application if the unit will display unchanging static content. Uninterrupted display of still or static images over an extended period may cause “burn in”,
also known as “after-imaging” or “ghost imaging”, on your screen. This is a well-known phenomenon in LCD panel technology. In most cases, the “burned
in” or “after-imaging” or “ghost imaging” will disappear gradually over a period of time after the power has been switched off.
WARNING: Severe “burn-in” or “after-image” or “ghost image” symptoms will not disappear and cannot be repaired. This is also not covered under the
terms of your warranty.
Service:
• The casing cover should be opened only by qualied service personnel.
• If there is any need for repair or integration, please contact your local service center.
• Do not leave your display under direct sunlight.
If your display does not operate normally, having followed the instructions set out in this document, please contact a technician or your
local service center.

• Unplug the display if you need to clean it with a slightly damp cloth. The screen many be wiped with a dry cloth when the power is
off. However, never use alcohol, solvents or ammonia-based liquids.
• Consult a service technician if the display does not operate normally when you have followed the instructions in this manual.
• The casing cover should be opened only by qualied service personnel.
• Keep the display out of direct sunlight and away from stoves or any other heat sources.
• Remove any object that could fall into the vents or prevent proper cooling of the display’s electronics.
• Do not block the ventilation holes on the cabinet.
• Keep the display dry. To avoid electric shock, do not expose it to rain or excessive moisture.
• When turning off the display by detaching the power cable or DC power cord, wait for 6 seconds before re-attaching the power
cable or DC power cord for normal operation..
• To avoid the risk of shock or permanent damage to the set do not expose the display to rain or excessive moisture.
• When positioning the display, make sure the power plug and outlet are easily accessible.
• IMPORTANT: Always activate a screen saver program during your application. If a still image in high contrast remains on the
screen for an extended period of time, it may leave an ‘after-image’ or ‘ghost image’ on the front of the screen. This is a well-known
phenomenon that is caused by the shortcomings inherent in LCD technology. In most cases the afterimage will disappear gradually
over a period of time after the power has been switched off. Be aware that the after-image symptom cannot be repaired and is not
covered under warranty.

proceed as follows:+
1. Remove fuse cover and fuse.
2. Fit new fuse which should be a BS 1362 5A,A.S.T.A. or BSI approved type.
3. Ret the fuse cover.
If the tted plug is not suitable for your socket outlets, it should be cut off and an appropriate 3-pin
plug tted in its place.
If the mains plug contains a fuse, this should have a value of 5A. If a plug without a fuse is used, the fuse
at the distribution board should not be greater than 5A.
NOTE: The severed plug must be destroyed to avoid a possible shock hazard should it be inserted
into a 13A socket elsewhere.
How to connect a plug
The wires in the mains lead are coloured in accordance with the following code:
BLUE - “NEUTRAL” (“N”)
BROWN - “LIVE” (“L”)
GREEN & YELLOW - “EARTH” (“E”)
