symbol, within an equilateral triangle, is
intended to alert the user to the
presence of uninsulated "dangerous
voltage" within the product's enclosure
that may be of sufficient magnitude to
constitute a risk of electric shock to
persons.

The exclamation point within an
equilateral triangle is intended to alert
the user to the presence of important
operating and maintenance (servicing)
instructions in the literature
accompanying the appliance.

Notes on the LCD panel of this display

• The Liquid Crystal Display (LCD) panel of this display has a very thin protective layer of

glass which is liable to marking or scratching, and cracking if struck or pressured. The
liquid crystal substrate is also liable to damage under excessive force or extreme
temperatures. Please handle with care.

• The response time and brightness of the LCD panel may vary with the ambient

temperature.

• Avoid placing the display in direct sun or where direct sun or spot lighting will shine

onto the LCD panel, as the heat may damage the panel and the external casing of the
display, and the bright light will make viewing the display more difficult than necessary.

• The LCD panel consists of individual pixels to display images and is manufactured

according to the design specifications. While 99.9% of these pixels work normally,

0.01% of the pixels may remain constantly lit (in red, blue or green) or unlit. This is a
technical limitation of the LCD technology and is not a defect.

• LCD screens, like plasma (PDP) and conventional CRT (Cathode Ray Tube) screens, are

also susceptible to 'screen burn-in' or 'image retention' which can be found on the

Important safety instructions 3

screen as visible fixed lines and shades. To avoid such damage to the screen, avoid
displaying still images (like On-Screen Display menus, TV station logos, fixed/inactive
text or icons) for more than 30 minutes. Change the aspect ratio from time to time. Fill
the entire screen with the image and eliminate the black bars whenever possible. Avoid
displaying images in 4:3 aspect ratio over a long period of time, otherwise there may be
visible burn marks on the screen as two vertical lines.
Note: Under certain circumstances, condensation may occur on the inner side of the
cover glass, it's a natural phenomenon and will not affect the operation of the display.
This condensation will usually disappear after around 2 hours of normal operation.

• RP series does not offer image retention function, for more information, please refer to
installation guide.

• RP series does not support portrait use; portrait use may cause display damage. BenQ
warranty will not cover faulty usage.

Safety notice for remote control

• Do not put the remote control in the direct heat, humidity, and avoid fire.

• Do not drop the remote control.

• Do not expose the remote control to water or moisture. Failure to do so could result
in malfunction.

• Confirm there is no object between the remote control and the remote sensor of the
product.

• When the remote control will not be used for an extended period, remove the
batteries.

Battery safety notice

The use of the wrong type of batteries may cause chemical leaks or explosion. Please
note the following:

• Always ensure that the batteries are inserted with the positive and negative terminals in
the correct direction as shown in the battery compartment.

• Different types of batteries have different characteristics. Do not mix different types.

• Do not mix old and new batteries. Mixing old and new batteries will shorten battery life
or cause chemical leaks from the old batteries.

• When batteries fail to function, replace them immediately.

• Chemicals which leak from batteries may cause skin irritation. If any chemical matter
seeps out of the batteries, wipe it up immediately using a dry cloth, and replace the
batteries as soon as possible.

• Due to varying storage conditions, the battery life for the batteries included with your
product may be shortened. Replace them within 3 months or as soon as you can after
initial use.

• There may be local restrictions on the disposal or recycling of batteries. Consult your
local regulations or waste disposal provider.

• Check for incorrect battery orientation.

• Check for dead batteries.

• Check your distance and angle from the display.

• Check whether remote control is properly being pointed
at the display’s remote control sensor window.

• Check for any obstacle between the remote control and
the remote control sensor window.

• Check that the remote control sensor window is not
under strong fluorescent lighting, or in direct sunlight.

• Check for any devices (computer or personal digital
assistant, PDA) nearby that transmit infrared signals which
may cause interference to signal transmission between the
