■

Check the peripheral environment and place of installation

- A nearby source of electromagnetic interference may prevent communication. In general locations

(excluding factories) the following may be sources of electromagnetic emissions.

- 5GHz band not conforming to IEEE802.11 (when using IEEE802.11a) or 2.4GHz band (when

using IEEE802.11b/IEEE802.11g) wireless network

- Electronic devices that give off 2.4GHz band radio waves, such as microwave ovens, security

gates installed near entrances of some shops, and copiers, when using

IEEE802.11b/IEEE802.11g

Most electromagnetic sources other than wireless networks are local and not continuous. Moving the

location of the product and waiting for a while may enable communication.

- Sometimes communication is hindered by attenuation of radio waves.

Attenuation occurs naturally as distance from the source of transmission increases, but may also be

caused by objects in the path of the transmission. The objects primarily responsible for attenuation

are the following.

- Concrete walls

- Metallic surfaces around this product

Setup Screen Unavailable on Web Browser

- Check if communication is possible between the product and PC.

- If no problem is detected in the communication between the product and PC, it may be related to

the browser settings. For the browser settings, see Chapter 3 “Connection to Devices and Setup

Methods”.

When the Product Does Not Start

■

Check the power LED

- Check whether the “POWER” LED is ON. If it is not ON, check the power supply cable and

confirm that it is properly connected to the proper connector and outlet.

- Check whether the Power LED is flashing. If the power LED still flashes for more than 5 minutes

after the power is switched on, the firmware of the product may be in failure.

Contact your local authorized dealer.

Check the power

- When power is supplied using the proper connector, check the power supply connection and the

voltage for any problems. See "Chapter 2. Setup" for details of the power supply connections.
