Precautions with regard to safety

Cautions on use

„„In order to get the picture quality

Draw curtains or blinds over windows and turn off any lights near the screen to prevent outside light or light from indoor lamps from shining onto the screen. Depending on where the projector is used, air exhaust vents or the warm air from air conditioning can cause a shimmering effect on the screen. For this reason, take care not to shield the air exhaust vents and con- sider the direction of the air flowing from air condition- ing.

„„Do not touch the surface of the projector lens cover with your bare hand.

If the surface of the lens becomes dirty from finger- prints or anything else, this will be magnified and projected onto the screen.

„„Liquid crystal panel

The Liquid crystal panels are precision-made. Note that in rare cases, pixels of high precision could be missing or always lit, but this is not a malfunction.

Do not project the same image for long periods of time, as this may remain as an afterimage on the liq- uid crystal panel. Display the white screen test pattern for more than an hour to remove it. See “TEST PAT- TERN” on page 42.

Security

„„Take safety measures against fol- lowing incidents.

cious third party.

zzInterfering or stopping of this product by a malicious third party.

Important Information

„„Do not move the projector while it is operating or subject it to vibra- tion or impact.

The service life of its internal components will be shortened.

„„The projector has a high pressure mercury lamp that is characterized as follows:

zzThe brightness of the lamp will decrease over time. zzThe lamp may explode or shorten the lamp life by

shocks or chipping damage.

zzIn rare cases, it may burst shortly after the first use.

zzThe possibility of its bursting increases when the lamp is used beyond the replacement time.

zzIf the lamp bursts, gas inside the lamp is released in the form of smoke.

zzThe life of a mercury lamp varies according to the individual difference or conditions of use.

zzIn particular, turning the power on and off frequently and/or repeatedly as well as continuous use for

10 hours will greatly affect the life cycle. Provide a lamp for replacement in advance.

„„Connection to external device

When connecting the projector to a computer or external device, use the power cord supplied with the corresponding device and a commercially available shielded interface cable.

„„Optical components

It may be necessary to replace the optical compo- nents such as Liquid crystal panels and Polarizing plates in less than 1 year if using the projector in a high temperature environment or in a very dusty, oily smoke or tobacco smoke environment. For more details, please contact your dealer.

„„Security instruction

zzThe connecting network must be secured by fire- wall or others.

zzChange your password regularly.

zzDo not use a password that is simple to guess.

zzPanasonic and its affiliate companies would never directly inquire about your password.

zzDo not share your password with the general pub- lic.

zzSet a password, and place restrictions on the users who can log in.

Cleaning and maintenance

„„Ask an Authorized Service Center to clean the inside of the projec- tor at least once a year.

If dust is left to build up inside the projector without being cleaned out, it can result in fire or problems with operation. It is a good idea to clean the inside of the projector before the season when humid weather ar- rives.

Ask your nearest Authorized Service Center to clean the projector when required.

Please discuss with the Authorized Service Center regarding cleaning costs.

Disposal

When discarding this product, please contact your lo- cal authorities or dealer and ask for the correct meth- od of disposal.
