PRECAUTIONS
OPERATOR SAFETY
1. PROTECTION FROM ELECTRIC SHOCK
* Before performing any repair work on the product, be sure to turn off the power
switch and remove the electric power cable from the electrical outlet.
* Whenever it is necessary to turn power on after opening the case or cover (for
example, during the adjustment process) be sure to remove anything you are
wearing that is metal, such as a watch, cuff links, ring, or tie pin, that may touch
metallic parts of the product, creating a danger of electric shock.
2. PROTECTION FROM INJURY
* Be sure not to touch the lamp and its surroundings after power is turned off; they
may be hot. Also, be sure not to touch the light source and its surroundings during
adjustments while power is turned on.
* Use gloves to protect your hands from sharp edges during assembly and
disassembly.
* To protect your eyes from being damaged, do not look into the light source or lens
while the light is on.
3. ACCIDENT PREVENTION
* To prevent the device or its components from falling, perform any operation only
after the device is placed on a flat and stable surface. Be careful not to place tools
or parts on top of the device or at your feet.
* To prevent this product from being used before it is totally reassembled, be sure
not to leave the product out during any repair work, and do not place it in a location
where it can be taken for use by mistake.
* Be sure to use attached power cable to supply power to the product.
PRODUCT SAFETY
1. ELECTROSTATIC DISCHARGE
* Whenever performing repair work on the product, be sure to wear a wrist band and
use an electrostatic mat for grounding. When you replace any electric components
(boards and light bulb), it is recommended that you touch the electrostatic plastic
bag containing the component to a metallic part of the product before taking the
component out of the plastic bag.
2. RESTRICTIONS FOR PARTS REPLACEMENT
* Use only authorized parts or EPSON-supplied parts for replacement of mechanical
components, including the light source lamp, fuse, air filter, and so on.
