Precautions - Sony SRX-R320 Operating Instructions Manual

Precautions

On safety
• Operate the unit on 200 V to 240 V AC, 50/60 Hz.
• Should any liquid or solid object fall into the cabinet,
turn off the unit and have it checked by Qualified Sony
Service Personnel before operating it further.
• Turn off the power switch if it is not to be used for
several days.
• The unit is not disconnected from the AC power source
(mains) as long as it is connected to the distribution
board and the power switch is turned on.
• Do not place your hand or objects near the ventilation
holes. The air coming out is hot.
• Use a lifter to carry the projector to avoid accidents or
injury.
• Do not catch your finger between the unit and surface of
the floor when moving the unit installed on the floor.
• Be careful not to catch your finger in the cooling fan.
• Since an intense light has come out of this projector from
the front, do not stand on the front of a projector for a
long time.
On cleaning
• To keep the cabinet looking new, periodically clean it
with a soft cloth. Stubborn stains may be removed with
a cloth lightly dampened with a mild detergent solution.
Never use strong solvents, such as thinner, benzene, or
abrasive cleansers, since these will damage the cabinet.
• Avoid touching the lens. To remove dust on the lens, use
a soft dry cloth. Do not use a damp cloth, detergent
solution, or thinner.
On repacking
Save the original shipping carton and packing material;
they will come in handy if you ever have to ship your unit.
For maximum protection, repack your unit as it was
originally packed at the factory.
On "stuck" pixels on a LCD screen
The LCD panel fitted to this unit is manufactured with high
precision technology. Thus a very small proportion of
pixels may be "stuck", either always off (black), always on
(red, green, or blue), or flashing. In addition, over a long
period of use, because of the physical characteristics of the
liquid crystal display, such "stuck" pixels may appear
spontaneously. These problems are not a malfunction.

Precautions
On dangerous areas in a case of lamp
explosion
Since a projector lamp can explode, it is dangerous to be in
the shaded areas shown in the illustrations below. Keep
away from the dangerous areas.
The danger radius (x) differs depending on the height (y)
between the bottom of the projector and the floor.
x = 20/3 × 10y + 6400
For example, in a case where the height (y) is 800 mm
1
(31 / in.), the danger radius (x) calculated by the formula
2
1
above is 800 mm (31 / in.)
