Installation and Adjustment Manual
Thank you for your purchase of this NEC wall mount unit.
Please read this installation and adjustment manual carefully to ensure proper use.
For a list of the supported projectors, please see the NEC website or NEC catalogs.
The descriptions in the installation and adjustments manual are mainly for the NP-
UM330X.
Special skills are required to install the wall mount unit. This
work should never be performed by the customer.
To the Dealer and Installer
To ensure customer safety, we ask that the installation work
be started after careful attention is paid to the strength of the
mounting location to ensure it will withstand the weight of the
projector and mounting hardware.

Warning
• Wheninstallingtheprojectorandadjustingtheprojectionposition,besuretodoso
as explained in this manual. The projector may fall and cause injury if installed and
adjusted improperly.
• Topreventtheprojectorfromfalling,installitinalocationandfastenitsoastoensure
sufficient strength to support the combined weight of the projector, the wall mount
unit and so on for an extended period as well as to withstand earthquakes. Insuffi-
cient strength or fastening may result in the projector falling and causing injury.
Be sure to observe the following precautions:
- Use M6 (1/4 inch) for the wall fixation bolts and screws for the wall adapter.
- Use an outlet for the power source of the projector. Do not directly connect to the
lamp line because this is dangerous.Also, use an accessible outlet so that you can
connect and disconnect the power plug.
- Mounting on a wooden wall
Ensure the load is mounted on a pillar or robust constructional material. If the
strength of the constructional material and so on is insufficient, please reinforce it.
Do not mount on wall finishing material, furring strip and so on.
- Mounting on a concrete wall
Use a commercial anchor bolt M6 (1/4 inch), anchor nuts and similar, which will bear
the load of the projector.

Warning
• Donotinstallinplacessubjecttoconstantvibration.Extendedvibrationmaycause
loosening of the screws and result in the Wall Mount Unit and projector falling and
causing injury. Also, it may cause breakdown of the projector.
• Toensuresafety,besuretotightenthebolts,screwsandsafetylockscrewssecure-
ly. Failure to do so may result in the projector falling and causing injury.
• Donotmodifyanyparts.DoingsomayresultintheprojectorandtheWallMountUnit
falling and causing injury.
• Donotusebrokenparts.DoingsomayresultintheprojectorandtheWallMountUnit
falling and causing injury. If a part should break, consult your dealer.
• Donotlookintotheprojectionwindow,mirrororlenswhentheprojectoristurned
on. Doing so could damage your eyesight.
• DonothangfromtheprojectorandtheWallMountUnit.Doingsomayresultinthe
projector and the Wall Mount Unit falling and causing injury. Be especially careful of
children.
• Donotuseadhesiveforthelockingscrews,lubricantagent,oilandsoonforthewall
adapter. Doing so may cause the material of the wall adapter to deteriorate and result
in the projector falling and causing injury.
Caution
• Donotobstructtheprojector’sventilationholes.Doingsowillpreventthedissipation
of heat and may result in fire. In particular, do not use the projector in the following
ways:
installing the projector in a place such as wall and so on where ventilation is poor,
covering it, etc.
• Donotinstalltheprojectorinfrontoftheoutletsofanairconditionerorheaterorin
a place exposed to significant vibrations. Doing so may result in fires and electric
shock.
• Do not install the projector in humid or dusty places or those exposed to greasy
smoke or steam (such as near cooking equipment or humidifiers). Doing so may result
in fires.
• Wheninstallingtheprojector,leavesufcientspacebetweenitandsurroundingob-
jects. Failure to do so will prevent the dissipation of heat and may result in fires.
Please:
• Avoidroomswithsignicantdust,humidity,greasysmoke,ortobaccosmoke.
Dirt will adhere to the optical parts such as mirrors and lenses, which will cause image quality
to deteriorate.
• Avoidplacesinwhichthescreenisexposedtodirectsunlightorilluminatedlight.
When surrounding light directly hits the screen, the image appears washed out and is difficult
to view.
• Avoidlocationsexposedtoparticularlyhighorlowtemperatures.
Doing so may result in breakdown. (For the ambient operating temperature, see the user’s
manual included with the projector.)

Before installing
1. Consider the place where the screen is to be installed and determine the position in
which the wall mount unit is to be mounted. (See page ENG-7)
- It is not possible to install in such a way that the image is projected at an angle. Position
in such a way that the image is projected directly to the front.
2. Check that the position of installation meets the conditions in “Be sure to
read before installing” on page ENG-2 of these instructions.
- Because the elevation angle of the projector’s optical axis is large, small shifts in the
projection distance will change the size and position of the projected image significantly.
Also, if the direction in which the projector is facing is off, the distortion of the image in-
creases.
