CHAPTER 3
DISPLAYS, MESSAGES, AND ALERTS
To conduct basic troubleshooting and maintenance of the i580 unit, you must become familiar with
the display screens, messages, and alert tones associated with the unit.
3.1 Power-Up Sequence
Extend the antenna whip and press the Power key until the power-up sequence begins. The power-
up sequence initiates a series of displays on the unit. Each display reflects a stage in the sequence.
If the last display shows the idle screen, the power up was successful; if the last display shows No
Service, the unit is out of range or there is a hardware or software problem. If the vibrate function is
enabled for incoming phone calls, voice mail, or message mail, the power-up sequence includes a
500ms vibrate cycle.
Depending upon the service provider, the power-up sequence screens may differ from those shown.
