Reading the Indicators (Continued)
Digital Indicator (2)
If you are in a digital coverage area, the indicator flashes.
In Use Indicator (3)
The In Use (IU) Indicator flashes when a call is in progress.
No Service Indicator (4)
If you travel beyond the range of a cellular system, the No 
Service (NS) Indicator flashes to let you know that calls 
cannot be placed or received from your location.
Roam Indicator (5)
The Roam (Rm) Indicator lights up when your phone 
accesses a cellular service outside your local cellular system. 
When you leave your cellular service area, your phone 
roams or seeks another cellular system until it finds one. 
If your phone finds another cellular service of the same 
system type as your local service, the Roam Indicator 
flashes slowly. If it finds a different system type, it flashes 
quickly.
