Safety Warnings, Cautions and Important Information
WARNINGS – GENERAL
• Do not climb (or allow children to climb) on any
part of your wall-mounted SMART Board
interactive whiteboard system.
• Climbing on the interactive whiteboard or
projector boom could result in personal injury or
product damage. Do not climb on, hang from or
suspend objects from the UX60 projector.
• To reduce the risk of fire or electric shock, do not
expose any component of your SMART Board
interactive whiteboard system to rain or moisture.

ii | INTRODUCTION – IMPORTANT INFORMATION
Part No. 99-00984-20 REV A0
• Failure to follow the installation instructions shipped with your SMART product
could result in personal injury and damage to the product.
• If you remove the three screws
supporting the adjustment module,
the projector will be free to move on
the wall-mounting bracket’s track.
Make sure that the screws are
tightened.
• Make sure that an electrical socket is
near your SMART product and
remains easily accessible during use.
• Two people are required to mount 
the projector and the interactive
whiteboard on a wall because they
could be too heavy for one person to
maneuver onto their wall-mounting
brackets.
• When mounting the projector on a
framed or hollow wall, you must
attach both the mounting bracket and
safety tether to a stud to safely
support the projector’s weight. If you
use only drywall anchors, the drywall
can fail, resulting in product damage
and possible personal injury.

Part No. 99-00984-20 REV A0
iii | INTRODUCTION – IMPORTANT INFORMATION
• When adjusting the projector’s image, only loosen the locking screw next to
the lock and unlock symbols (see the following illustration in grey). Never
loosen other screws or loosen the center nut attached to the projector bolt as
your projector may fall.
• Ensure that any cables extending across the floor to your SMART product are
properly bundled and marked to prevent a trip hazard.
• Cleaning a wall-mounted projector can result in a fall or injury. Use caution
when climbing a ladder, or remove the projector from the wall-mounting
bracket to clean it.
WARNINGS – PROJECTOR
• Do not stare (or allow children to stare) directly into the beam of light created
by the projector. Instruct children not to look in the direction of, or stare at, this
beam of light. Encourage users to keep their back to the projector when
working at the interactive whiteboard. Before they turn to face the audience,
users should step sideways, out of the projector’s beam.
• Do not attempt to service the projector other than performing routine lamp
replacement. Other than the lamp module, there are no user-serviceable
parts inside the unit. Do not open or disassemble the projector as this may
cause electric shock.
• This projector detects its remaining lamp life. Replace the lamp when a lamp
life warning message appears. If you continue to use the projector after the
replacement message appears, the lamp can shatter or burst, scattering
glass throughout the projector.

iv | INTRODUCTION – IMPORTANT INFORMATION
Part No. 99-00984-20 REV A0
• If the lamp has shattered or burst:
– Call an authorized SMART reseller for instructions. Do not attempt to
replace the lamp.
– Do not touch the glass fragments because they can cause injury.
– Leave and then ventilate the area where the lamp shattered or burst.
– Wash your hands thoroughly if you have come into contact with 
lamp debris.
– Thoroughly clean the area around the projector, and discard any edible
items placed in that area because they could be contaminated.
• Replacing the lamp in a wall-mounted projector can result in a fall or injury.
Use caution when climbing a ladder, or remove the projector from the wall-
mounting bracket to replace the lamp.
– Uncovering the lamp while the projector is mounted on the wall-mounting
bracket can lead to product damage or personal injury from falling pieces
of glass if the lamp is broken.
• When replacing the projector lamp:
– Turn off the projector and wait 30 minutes for the lamp to cool 
completely (or before removing the projector from the wall-mounting
bracket, if necessary).
– Do not remove any screws other than those specified in the lamp
replacement instructions.
– Wear protective eyewear while changing the lamp. Failure to do so can
cause injury or loss of eyesight if the lamp shatters or bursts.
– Use only replacement lamps approved by SMART Technologies. Contact
your authorized SMART reseller for replacement parts.
– Never replace the lamp assembly with a previously-used lamp assembly.
– To prevent premature lamp failure or exposure to mercury, always handle
the fragile lamp assembly with care. Use gloves when touching the lamp.
Do not touch the lamp with your fingers.
– Recycle or dispose of the lamp as hazardous waste, in accordance with
local regulations.
• When returning the projector to the wall-mounting bracket, replace all of the
screws you removed when you removed the projector. Failure to do so 
can result in the projector falling from the boom resulting in injury or
equipment damage.

Part No. 99-00984-20 REV A0
v | INTRODUCTION – IMPORTANT INFORMATION
• Reduce the risk associated with a leaking battery in your projector’s remote
control:
– Use only the specified coin-cell type battery
– Orient the battery’s plus (+) and minus (-) terminals according to the
markings on the remote control
– Remove the battery when the remote control is unused for an extended
period
– Do not heat, disassemble, short or recharge the battery, or expose it to
fire or high temperatures
– Avoid eye and skin contact if the battery has a leak
– Dispose of the exhausted battery and product components in accordance
with applicable regulations
CAUTIONS
• Avoid turning off the projector during the lamp ignition phase because this can
lead to premature lamp failure. Before turning off the projector, keep the lamp
on for a minimum of 15 minutes after turning it on to preserve the lamp life.
• When you switch the projector off, ensure that the cooling cycle is complete
before disconnecting the power. Allow 90 seconds for the projector to
complete the cooling cycle.
• Never operate this unit immediately after moving it from a cold location to a
warm location. When the unit is exposed to such a change in temperature,
moisture can condense on the lens and crucial internal parts. Allow the
system to reach room temperature before operation to prevent possible
damage to the unit.
• In a high altitude location where the altitude is over 6000' (1829 m), where the
air is thin, cooling efficiency is reduced, so use the projector with the fan mode
set to High.
• Do not block the projector’s ventilation slots and openings.
• Do not place in hot locations, such as near heating equipment. Doing so could
cause a malfunction and shorten the life of the projector.
• Do not set up or use the interactive whiteboard system in an area with
excessive levels of dust, dirt, humidity or smoke.
• Before you clean the UX60 projector, put the system into Idle mode by
pressing the power button twice on the ECP or remote and allow the bulb to
cool for at least 30 minutes.

vi | INTRODUCTION – IMPORTANT INFORMATION
Part No. 99-00984-20 REV A0
• Do not allow liquids or commercial solvents of any kind to flow into the
projector base or head. Do not use spray cleaners or solvents near any part of
the projector, because they can damage or stain the unit.
• Cycling power to the projector repeatedly can lock or damage the interactive
whiteboard system. After you turn off the system, wait at least 15 minutes for
cooling before turning on the system.
• You must connect the USB cable that came with your SMART Board
interactive whiteboard to a computer that has a USB compliant interface and
that bears the USB logo. In addition, the USB source computer must be
compliant with CSA/UL/EN 60950 and bear the CE mark and CSA and/or UL
mark(s) for CAS/UL 60950. This is for operating safety and to prevent
damage to the SMART Board interactive whiteboard.
• Do not add extra weight or apply pressure to the UX60 projector boom, the
wall-mounted interactive whiteboard or its pen tray. SMART Technologies
designed the brackets to support only the weight of the components during
normal use.
• If the interactive whiteboard system requires replacement parts, make sure
that the service technician uses replacement parts specified by SMART
Technologies, or parts with the same characteristics as the original.
IMPORTANT
• Turn off the SMART product before cleaning it.
• Using the UX60 projector system near a TV or radio can cause interference 
to the images or sound. If this happens, move the TV or radio away from 
the projector.
• Do not place the interactive whiteboard system near any appliance that
generates a strong magnetic field.
• Do not place the interactive whiteboard system in direct sunlight.
• The screws that secure the interactive whiteboard to the wall are located
directly behind the pen tray. The pen tray must be removed before you can
remove the interactive whiteboard. When you secure the pen tray, you also
secure the interactive whiteboard.
• The SMART Board 685ix interactive whiteboard system does not include
speakers. Consult your authorized SMART reseller to determine your audio
output options.
• If you have peripheral devices that do not use a 4-pin mini-DIN connector, an
HDMI connector or an RCA composite video jack, or if your device has an
audio connection that does not use RCA jacks or 3.5 mm plugs, you might
need to purchase third-party adapters.

Part No. 99-00984-20 REV A0
vii | INTRODUCTION – IMPORTANT INFORMATION
• Disconnect the product from its power source when it is not used for a 
long period.
• When cleaning the interactive whiteboard system:
– Wipe the exterior of the projector using a lint-free cloth
– If necessary, use a soft cloth moistened with a mild detergent to clean the
projector housing.
– Do not use abrasive cleaners, waxes or solvents
Transporting the SMART Board 685ix Interactive 
Whiteboard System
If you need to ship any part of your SMART Board 685ix interactive whiteboard
system, repack it with the original packaging. If the original packaging is no longer
available, you can purchase replacement packaging from your authorized SMART
reseller.
If you prefer to use your own packaging materials, make sure that you adequately
protect the unit. Ship the interactive whiteboard in an upright position to deter shippers
from placing heavy objects on it.

5 | CHAPTER 1 – ABOUT YOUR SMART BOARD 685IX INTERACTIVE
WHITEBOARD SYSTEM
Standard Accessories
SMART provides the following accessories with your SMART Board 685ix interactive
whiteboard system.
Standard SMART Board Interactive Whiteboard Accessories
Pen Tray Tools
The pen tray tools include four pens and an eraser. The pens
have a rubberized grip area, colored to match the four colors
of digital ink: black, green, red and blue. You can use
dry-erase markers instead of the supplied pens, as long as
they’re a similar shape, don’t scratch or mark the surface of
the interactive whiteboard. If the pens you provide don’t reflect infrared light, the pen
tray sensor might not detect the presence of the pen. You can use EXPO® markers or
other substitutes.
Pens from earlier interactive whiteboards weren’t designed to reflect infrared light, so
the pen tray might not detect them reliably. You can wrap light-colored tape around
the pen to improve the reflection of infrared light and to help with tool detection.
Eraser
The eraser resembles a rectangular chalkboard eraser. 
You can use a substitute eraser, provided it has a similar
shape, reflects infrared light and doesn’t scratch or mark
the surface of the interactive whiteboard.
Standard UX60 Projector Accessories
Remote Control
The remote control lets you control the system and set up
your UX60 projector. Use the remote control to access menu
options, system information and input selection options.
