Installation Procedure
• When installing this option, turn OFF the main power and unplug the power cord from the wall
socket. If installing without turning OFF the main power, an electric shock or a malfunction may
occur.
• Do not put your hand into the controller box. It will result in a malfunction or injury.
• Before doing any work, touch a metal object to discharge static electricity from the body. There is a
possibility that the extension wireless LAN board may malfunction due to static electricity.
• When using wireless LAN (IEEE802.11 b/g/n:2.4-GHz band), this radio product uses the 2.4-
GHz band. Check that industrial, scientific and medical devices using the same frequency bands,
such as a microwave oven or a cordless telephone, are not used nearby.
• If there is interference, communication may become unstable. Check that there are no devices likely
to cause interference in the surrounding area.
