• Make sure you have four or more people available to help lift or a flat cart to transport
the display to its final location.
• Keep the display horizontal as much as possible.
• Clear a floor space before unpacking.
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.
Page 7
Important safety instructions3
• 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
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. If a still image is required for a display, it is recommended to enable
Pixel Shift. SeeAdjust settings (VGA-only) on page 40for more information.
• 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.

visuals (for example, a tooltip or context menu) to be displayed
without a commitment to an action. Anything displayed this way

GestureDescription
Slide to pan
Slide is primarily used for panning interactions but can also be
used for moving, drawing or writing. Slide can also be used to
target small, densely packed elements by scrubbing (sliding the
finger over related objects such as radio buttons).
Swipe to select, command, and move
Sliding the finger a short distance, perpendicular to the panning
direction, selects objects in a list or grid (ListView and
GridLayout controls). Display the AppBar with relevant
commands when objects are selected.
Pinch and stretch to zoom
While the pinch and stretch gestures are commonly used for
resizing, they also enable jumping to the beginning, end, or
anywhere within content with Semantic Zoom. A
SemanticZoom control provides a zoomed out view for showing
groups of items and quick ways to dive back into them.
Turn to rotate
Rotating with two or more fingers causes an object to rotate.
