
When the DHCP server is connected to the network and the DHCP Client parameter is set to "on," you need not set the IP
address because it is automatically set. When the DHCP server is not connected to the network and you wish to set a specific
IP address, set the DHCP Client parameter to "off," then set the IP address manually.


If the network settings do not become active even if you set the related parameters, make sure to press the [ENTER] button
after setting. Then, you will need to press the [STORE] button to store the settings. If you do not store the network settings,
these will be erased after you turn off the power.


The characters of a file or directory may be garbled when loading the file from the computer drive to the MOTIF XF. If such a
problem occurs, replace the garbled character with the correct one on the MOTIF XF display. Keep in mind that 2-byte
character codes such as Kanji and Kana cannot be shown on the display of the MOTIF XF.

When "Password is unspecified." appears after setting the File Server parameter to "on," make sure to set the Password
before setting the File Server parameter to "on." This is because the Security parameter has been set to "workgroup" and the
Account and Password are necessary when the files are shared.
