Precautions with regard to safety Important Information 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 consider the direction of the air flowing from air conditioning. „„Do not touch the surface of the projector lens cover with your bare hand. If the surface of the lens becomes dirty from fingerprints or anything else, this will be magnified and projected onto the screen. „„Do not move the projector while it is operating or subject it to vibration 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 components 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. „„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 liquid crystal panel. Display the white screen test pattern for more than an hour to remove it. See "TEST PATTERN" on page 42. Security „„Take safety measures against following incidents. zzPersonal information being leaked via this product. zzUnauthorized operation of this product by a mali- cious third party. zzInterfering or stopping of this product by a malicious third party. „„Security instruction zzThe connecting network must be secured by firewall 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 projector 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 arrives. Ask your nearest Authorized Service Center to clean the projector when required. Please discuss with the Authorized Service Center regarding cleaning costs.
