Quick Reference Guide

• Screen image does not display properly when the screen layout is changed.

• The Contact List or contact status do not appear, or it takes longer than expected for

each to be displayed.

• The attempt to update the firmware fails, or it takes an excessively long time for the

update to finish.

• The machine does not start.

• You cannot connect to other party.

If you experience one of the problems above, take one of the following actions. The action to

be taken depends on the wireless network environment you are using:

• If IEEE802.11b and IEEE802.11g are in the same wireless network environment, the

IEEE802.11b connection may be used first. The recommended line speed for the

machine is 1 Mbps. To use the machine at a stable line speed, we recommend using it in

a wireless network environment in which only IEEE802.11g is available.

• Avoid environments that have multiple wireless LAN standards.

• Turn off any wireless networking or radio devices that are not being used.

• If there are multiple devices in the environment that support IEEE802.11n, use

IEEE802.11n with a single channel.

• Use the machine in an environment with stable reception, making sure to confirm the

distance from the access point and check for any obstructions.

• If the environment has multiple wireless LAN standards, change the access point channel.

There should be a difference of at least five between the channel settings for each LAN

standard. For example, set one standard to channel 1 and the other to channel 6.

• Keep the machine as far away as possible from highly conductive objects such as metal.

• This wireless product uses the 2.4 GHz band. Make sure there is no industrial, scientific,

or medical equipment that uses the same frequency band currently in operation, such as

a microwave. Interference can cause communication to become unstable. Before using

the machine, make sure that there is no equipment around that may potentially cause

interference.

• If you experience radio interference or other wireless networking problems, please call

the support desk.

Use this machine in an environment that meets the following conditions:
