Other Warnings and Safety Precautions
For operating safety and to avoid damaging the unit, follow these warnings and precautions.
• Move the cabinet with care. Quick stops, excessive force and uneven surfaces can
overturn the cabinet.
• When you transport the 4000i, only ship the cabinet in the upright position and never
lay the screen facedown. In addition, ensure that the projector is secure, or remove
and repackage it in the original packaging.
• If you transport the 4000i over a distance, we strongly urge you to completely
repackage it using the original packaging. This packaging was designed with optimal
shock and vibration protection. If the original packaging is no longer available, pack all
components with as much padding as reasonably possible to ensure that they are not
exposed to excessive vibration or shock.
• If you need to disassemble or assemble the cabinet, we strongly recommend that you
obtain assistance to do this.
• Do not touch the rear surface of the interactive whiteboard or apply isopropyl alcohol,
water or acetone. If any of these fluids come into contact with this surface, the
diffusion coating on the rear of the interactive whiteboard will be damaged, resulting in
a permanent deterioration in display quality.
• If you inadvertently smudge the rear surface of the interactive whiteboard, wipe it
carefully with a soft cloth and alcohol-free glass cleaner. Do not spray the glass
cleaner directly onto the surface; spray it lightly on the cloth, and then gently dab the
rear surface of the interactive whiteboard until the marks are removed.
• The 4000i uses digital cameras that are located inside the screen frame. These
cameras could be damaged if excess glass cleaner flows into the crack between the
frame and the writing surface.
• Avoid setting up and using the 4000i in an area with excessive levels of dust, humidity
or cigarette smoke, or where it’s exposed to extreme heat or cold. The operating
temperature range is from 41°F to 85°F (5°C to 29°C) with up to 80% humidity (non-
condensing). The shipping and storage range is from -4°F to 95°F (-20°C to 35°C)
with up to 80% humidity (non-condensing).
• Lock the casters after you set up the cabinet, so it remains stationary while in use.
• Unplug the cabinet during electrical storms or if you won't use it for an extended
period of time.
• Use safe practices when you’re plugging the power cable. For example, plug it in with
dry hands and don’t insert it into a dusty outlet. Unplug the cabinet before you install
or service any components.
• This product comes with a grounding-type power plug and a cable that’s specific for
the country in which you purchased it. This plug will only fit into a grounding-type
power outlet. If you are unable to insert the plug into the outlet, contact your electrician
to replace the outlet.
• Use the power supply that came with the 4000i. Also, do not modify its power cable.
Handle it carefully and avoid excessive bending. Route the power cable so it’s unlikely
to be walked on or pinched by items placed upon or against it. If you must run a cable
over the floor, lay it in a flat, straight line and secure it to the floor with tape or a cable
management strip of contrasting color.
