f LAN function is not available for PT-LB306.
rSecurity when using the wireless LAN product
(Only for PT-LW376, PT-LW336, PT-LB426, PT-LB386 and PT-LB356) The advantage of a wireless LAN is that information can be exchanged between a computer or other such equipment and a wireless access point using radio waves, instead of using a LAN cable, as long as you are within range for radio transmissions. On the other hand, because the radio wave can travel through an obstacle (such as a wall) and is accessible from anywhere within a given range, following problems may occur if security setting is insufficient. f Transmitted data may be intercepted
A malicious third party may intentionally intercept radio waves and monitor the following transmitted data. g Personal information such as your ID, password, credit card number g Content of an Email f Illegally accessed A malicious third party may access your personal or corporate network without authorization and engage in the following types of behavior. g Retrieve personal and/or secret information (information leak) g Spread false information by impersonating a particular person (spoofing) g Overwrite intercepted communications and issue false data (tampering) g 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, be sure to make all security related settings according to the operation instructions supplied with each wireless LAN device before using a wireless LAN device. Depending on the specifications of the wireless LAN, a malicious third party may be able to break security settings by special means. Panasonic Connect Co., Ltd. asks customers to thoroughly understand the risk of using this product without making security settings, and recommends that the customers make security settings at their own discretion and responsibility.
Notes on using wireless connection
(Only for PT-LW376, PT-LW336, PT-LB426, PT-LB386 and PT-LB356) Wireless connection function of the projector uses radio waves in the 2.4 GHz band.

The wireless module (Model No.: AJ- WM50 / ET-WML100) of optional accessories must be installed when you want to use the wireless LAN function of this projector.
rDo not use near other wireless equipment.
The following equipment may use radio waves in the same band as the projector. When the projector is used near these devices, radio wave interference may make communication impossible, or the communication speed may become slower. f Microwave ovens, etc. f Industrial, chemical and medical equipment, etc. f In- plant radio stations for identifying moving objects such as those used in factory manufacturing lines, etc. f Designated low-power radio stations
20 – ENGLISH

Chapter 1 Preparation – Precautions for use
r If at all possible, avoid the use of cell phones, TV sets or radios near the projector.
Cell phones, TV sets, radios and similar devices use different radio bands from the projector, so there is no effect on wireless communication or the transmission and reception of these devices. However, radio waves from the projector may produce audio or video noise.
r Wireless communication radio waves cannot penetrate steel reinforcements, metal, concrete, etc.
Communication is possible through walls and floors made from materials such as wood and glass (except glass containing wire mesh), but not through walls and floors made from steel reinforcements, metal, concrete, etc.
r Do not use the projector as much as possible in a location where static electricity is generated.
The communication via wireless LAN or wired LAN may be prone to disruption when the projector is used in a location where static electricity or noise is generated. There is a rare case that the LAN connection may not be established due to static electricity or noise, so in such case, turn off the projector, remove the source of problematic static electricity or noise, and turn the projector back on.
rUsing the projector outside the country
Note that depending on countries or regions there are restrictions on the channels and frequencies at which you can use the wireless LAN.

Chapter 1 Preparation – Precautions for use

Cautions on use

rTo get a good picture quality
In 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.

rProjection lens

f Do not touch the surface of the projector lens with your bare hands.
If the surface of the lens becomes dirty from fingerprints or anything else, this will be magnified and projected onto the screen.

f Do not wipe the lens during operation.
Cleaning the lens during operation may cause foreign objects adhering to the lens or bring damage to the lens surface.

rLCD Panel

Indicated on the projector

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.

rOptical 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.

r Lamp

The luminous source of the projector is a mercury lamp with high internal pressure.
A high pressure mercury lamp has following characteristics. f The brightness of the lamp will decrease by duration of usage. f The lamp may burst with sound or shorten life by shock or chipping. f 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. f In rare cases, the lamp burst shortly after the projection. f The risk of bursting increases when the lamp is used beyond its replacement cycle. Make sure to replace the lamp unit consistently. (“When to replace the lamp unit” (x page 124), “Replacing the lamp unit” (x page 125)) f If the lamp bursts, gas contained inside of the lamp is released in a form of smoke. f It is recommended to store replacement lamps for contingency.
