Chapter 1 Preparation - Precautions for use Notes on Using Wireless Connection Wireless connection function of the projector uses radio waves in the 2.4 GHz band. A radio station license is not required, but be sure to read and fully understand the following items before use. The wireless module (Model No.: ET-WML100) of optional accessories must be installed when you want to use the wireless LAN function of this projector. rrDo 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. ffMicrowave ovens, etc. ffIndustrial, chemical and medical equipment, etc. ffIn-plant radio stations for identifying moving objects such as those used in factory manufacturing lines, etc. ffDesignated low-power radio stations. rrIf at all possible, avoid the use of cellular phones, TV sets or radios near the projector. Cellular 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. rrWireless 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. rrAvoid using the projector in locations prone to static electricity. If the projector is used in a location prone to static electricity, such as on a carpet, the wireless LAN or wired LAN connection may be lost. If the static electricity or noise make it impossible to establish a connection with the LAN, please press the power button on the remote control or the control panel to power off the projector, and eliminate the source of static electricity or noise, then turn on the projector. rrUsing 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. rrAvailable wireless LAN channels The channels (frequency range) that can be used differ according to the country or region.
