Hitachi Projector Accessories HAS-K250 用户手册

ENGLISH

■  Do not attempt to install the projector yourself. Have your dealer or service center handle all 

installation work. Note that Hitachi will accept no liability whatsoever for accidents or injuries 
resulting from an incorrect installation or improper use.

■  Make sure that the projector is installed high enough so that there is no risk of people bumping their 

heads. If a sufficiently high installation cannot be made, be sure to take the necessary precautions 
when the projector is used. 

■  Do not hang on the LCD projector or the arm after installation as this could cause the LCD projector 

to fall down or bend the arm resulting in injury or damage. 

■  Do not install the projector in a location exposed to high humidity, dust or tobacco smoke or in a 

location exposed to smoke or steam. 

■  Do not install the projector in a location exposed to vibrations. 

■  After you have finished installation, keep this manual and accessories in a safe place for future 

reference.

■  Small parts such as screw caps and adjusting knobs could be swallowed by children and pets 

and should be kept out of their reach. If your child swallows any small parts, consult a doctor 
immediately. 

■  Perform all installation work correctly according to this manual. Make sure that all specified screws 

and brackets are used in the installation.

■  Considerable care is required in planning and performing the installation so that it will support the 

weight of the LCD projector and wall mount unit. 

■  Never attempt to modify the wall mount unit. (We will not guarantee the strength of a unit that has 

been modified.) 

■  Make sure that all screws are tightened to the proper torque after installation and adjustments. There 

must be no loose or over tightened screws. 

■  Do not use adhesives, lubricants, lubricating oils or other chemicals designed to prevent loosening 

of fasteners on screws and bolts used to secure the projector ceiling mount. The use of such 
materials could cause the mount to fail and the projector to fall resulting in damage or injury.

■  Route electric cables as prescribed and take care not to damage them in the installation work. 

■  Be sure to read this manual and the User’s Manual of the LCD projector prior to installation to 

ensure that all safety instructions are observed and the projector is correctly installed.

■  Be sure to turn off the LCD projector and disconnect the power plug from the wall outlet before 

starting installation work. 

Like the projector, the wall mount unit should be inspected once a year. 
1. Check that the screws in the wall mount unit and adjusted parts are not loose. 
2.  Check that the wall mount unit, adjusted parts and the set are not scarred or damaged.
