Avoid using in locations where exhaust or streams of air from the projector, other devices, and air conditioners flow between the projector and the screen.
    • The lens of the projector is affected by the heat from the luminous source. Because of this, the focusing may not be stable right after the power is turned on. Focusing is stabled after projecting an image for 30 minutes and longer.
  • Do not touch the surface of the projector lens 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.

What do I need to know about the LCD Panel?

The display unit of this projector comprises three LCD panels. Although an LCD panel is a product of high-precision technology, some of the pixels on the projected image may be missing or constantly lit. Please note that this is not a malfunction. Displaying a still image for a longer time may result in an after-image on the LCD panels. If this happens, display the all-white screen in the Test pattern for an hour or more.

What do I need to know about the optical components?

Operating the projector in an environment with high temperature or heavy exposure to dust or tobacco smoke will reduce the service life of the optical components, such as the LCD panel and polarizing plate, and may necessitate their replacement within less than one year of use. For details, consult your dealer.

What do I need to know about the lamp?

The luminous source of the projector is a mercury lamp with high internal pressure. A high-pressure mercury lamp has the following characteristics:

  • The brightness of the lamp will decrease by duration of usage.
  • The lamp may burst with sound or shorten life by shock or chipping.
  • The life of the lamp varies greatly depending on individual specificities and usage conditions. In particular, continuous use over 6 hours and frequent on/off switching of the power greatly deteriorate the lamp and affect the lamp life.
  • In rare cases, the lamp burst shortly after the projection.
  • The risk of bursting increases when the lamp is used beyond its replacement cycle. Make sure to replace the lamp unit consistently.
  • If the lamp bursts, gas contained inside of the lamp is released in a form of smoke.
  • It is recommended to store replacement lamps for contingency.

The frequency and channel differ depending on the country. Please use the wireless LAN feature in compliance with the laws of each country.

What is there to know 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.

  • A 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.
  • A 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 the 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 makes security settings at their own discretion and responsibility.
