Chapter 1 Preparation - Precautions for use About Wireless LANs The advantage of a wireless LAN is that information can be exchanged between a PC or other such equipment and an access point using radio waves as long as you are within range for radio transmissions. On the other hand, because the radio waves can travel through obstacles (such as walls) and are available everywhere within a given range, problems of the type listed below may occur if security-related settings are not made. ffA malicious third-part may intentionally intercept and monitor transmitted data including the content of e-mail and personal information such as your ID, password, and/or credit card numbers. ffA malicious third-party may access your personal or corporate network without authorization and engage in the following types of behavior. Retrieve personal and/or secret information (information leak) Spread false information by impersonating a particular person (spoofing) Overwrite intercepted communications and issue false data (tampering) Spread harmful software such as a computer virus and crash your data and/or system (system crash) Since most wireless LAN adapters or access points are equipped with security features to take care of these problems, you can reduce the possibility of these problems occurring when using this product by making the appropriate security settings for the wireless LAN device. Some wireless LAN devices may not be set for security immediately after purchase. To decrease the possibility of occurrence of security problems, before using any wireless LAN devices, be absolutely sure to make all security-related settings according to the instructions given in the operation manuals supplied with them. Depending on the specifications of the wireless LAN, a malicious third-party may be able to break security settings by special means. Panasonic asks customers to thoroughly understand the risk of using this product without making security settings, and recommends that the customer make security settings at their own discretion and responsibility. Early Warning Software The projector supports "Early Warning Software", which monitors the status of the display (projector and flat panel display) and the peripheral devices inside an intranet, and notifies of abnormality of such equipment and detects signs of possible abnormality. Also, maintenance can be performed in advance, because this software gives notification of approximate time to replace consumables of the display, to clean each part of the display, and to replace the components of the display. Depending on the type of license, the number of displays that can be registered for monitoring varies. Limited to the first 90 days after installation in a computer, it is possible to register up to 2048 units of displays free of charge. Download the software from Panasonic website (http://panasonic.net/avc/projector/pass/). It is necessary to register and login to PASS*1 to download. *1 PASS: Panasonic Professional Display and Projector Technical Support Website Refer to Panasonic website (http://panasonic.net/avc/projector/pass/) for details. Cautions on use rrTo get a good picture quality ffIn order to view a beautiful image in higher contrast, prepare an appropriate environment. 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. rrDo not touch the surface of the projection lens with your bare hands. If the surface of the projection lens becomes dirty from fingerprints or anything else, this will be magnified and projected onto the screen. Attach the lens cover supplied with the projector or with the optional projection lens to the projector when you do not use the projector. ENGLISH - 21
