2. The phone screen displays these messages as the phone starts up:
• Locating Network Services
• Configuring IP
• Network Up
• Configuring CMList
• Registering
3. The following information displays on the main phone screen:
• Current time and date
• Primary directory number
• Main screen icons for four menus and Help
• “Your current options” on status line
• Softkey labels (Messages and Options)
When the phone passes through these stages with no errors, the phone started up
properly. Now the phone is in standby mode and is ready to place or receive calls.
The signal icon in the upper left corner shows the strength of the signal between
the wireless access point and the phone. The phone must have an adequate signal
to successfully place or receive calls. If the signal icon displays only one bar, the
weak signal can cause problems with phone performance.
Note The status message, “Leaving Service Area” indicates that the phone is not
receiving a strong signal.
If the phone does not complete these steps successfully, see the “Resolving
Startup and Connectivity Problems” section on page 9-1.
