Operating Instructions
Possible Cause & Solution
•
You connected a USB device that this unit does not support.
→
This unit supports only standard USB keyboards.
•
The maximum number of chained hubs has been exceeded.
→
The maximum number of hubs you may chain together is 2.
•
The USB keyboard is not connected correctly.
→
Check whether the keyboard is connected correctly (Page 108). If
it is not connected correctly, disconnect it, and then connect it
again.
•
The locale of the keyboard is different from the locale selected for the
unit.
→
When you specify a locale for the unit in the [Language &
keyboard] settings (Page 122), the USB keyboard type is set to
the same locale. Therefore, if you use a keyboard designed for a
different locale from the one specified, the character that appears
on the screen when you press a key may differ from the character
printed on the keyboard. (For example, if the locale is "French" but
you use a US keyboard, pressing the [Q] key causes an "A" to
appear on the screen.)
•
You are using a key that is not supported by this unit.
→
Confirm which keys are supported (Page 29).
Possible Cause & Solution
•
You are on a call.
→
When you finish the call, try configuring the settings again.
•
You moved to another screen while configuring settings.
→
If you move to another screen while making changes, those
changes may not be saved. Configure the settings again as
necessary.
Possible Cause & Solution
•
The network settings are incorrect.
→
Consult your administrator or dealer.
•
The Ethernet cable is not connected correctly.
→
Check whether the Ethernet cable is connected correctly to the unit
(Page 105). If it is not connected correctly, disconnect it, and then
connect it again.
