PHONE START UP AND MENU
SCREEN
(Firmware version 4.0.0.0 and later)
The Portal screen that is displayed right after starting
up the phone depends on whether you start up the
phone by using an XML application with its home URL
registered or without its home URL registered. This
section provides sample screen displays for both
cases, and explains how to start up the menu screen.
• STARTING UP THE PHONE (with a
home URL registered)
• The phone automatically accesses the home
URL, and displays the received XML applica-
tion as Portal screen.
• Click to display the menu screen.
The screen that is to be displayed as the Portal
icon is the screen of the XML application that is reg-
istered as the home URL.
TIP
HOME URL:
A home URL is the address information of the applica-
tion that is to be accessed first after the phone is started.
Home URL registration is performed at installation. For
details, contact the system administrator.
PORTAL SCREEN:
A Portal screen is the home (entrance) screen of the
phone. When you use multiple XML applications, the
URL that is registered as the home URL is the Portal
screen: this is where other XML applications can be
accessed.
When a home URL is not registered, the default home
screen of the phone (Desktop screen or DESI-less
screen) is the Portal screen.
Note
The following XML application screen or the Portal
screen icon is a sample. The actual screen that is dis-
played on your phone may vary depending on the appli-
cation you use.
