Otherwise, deformation, discoloration, malfunctioning and/or problems in operation may result. Operate the unit where it will not be splashed or sprayed by water.  Concerning the installation location Install the unit in a stable location which will not be susceptible to shaking. If the unit is installed in a location which is susceptible to shaking, this will cause the unit's images to shake in turn. Install the unit after conferring in detail with your dealer. Install the unit on a ceiling that is strong enough (such as a concrete ceiling). If the unit is to be installed on a ceiling which is not strong enough, reinforce the ceiling sufficiently first.  Use the unit with an installation where the unit is suspended from an overhead surface or with a stand-alone installation. Do not use the unit on its side or tilted at an angle. [Note]  Be absolutely sure to use the four bracket mounting screws (M4) for mounting the mount bracket. These are supplied with the unit. Do not use wood screws, nails, etc. In the case of a concrete ceiling, secure the unit using anchor bolts (for M4) or AY plug bolts (for M4). Recommended clamping torque M4 : 1.47 N · m {15 kgf · cm}  The withdrawal strength of the mounting location for each screw must be at least 461 N {47 kgf}.  When mounting the unit on a ceiling made of plasterboard, for instance, if it is not strong enough to support its weight, either reinforce the ceiling adequately or use the WV-Q105A direct ceiling mount bracket, which is sold separately.  When using a mount bracket which is sold separately, read the handling instructions. 9
