If you have a poor connection:

> The problem may be at the other end; press 

G to cancel the

connection and place your call again.

> You may be calling from a fringe coverage area.  Check your

coverage map.  Check the signal strength indicator on your
handset display.  Notify Omnipoint Customer Care if you
consistently have trouble in a particular location when
coverage is available according to your Omnipoint coverage
map.

If you hear a tone while on a call:

> Your battery may be low.  A long tone warns you that about two

minutes of calling power remain.  Short tones tell you that
battery power is exhausted and your handset will shut off.

> Another call may have come in for you.  (See p. 45 for notes

on how to use Call Waiting/Call Hold.)

If your handset or SIM Card is lost or stolen:

> Don’t delay!  Notify Omnipoint Customer Care immediately at

1-888-OMNI-611.  We can deactivate your SIM and help
prevent unauthorized use.

But because your handset operates over radio frequencies, you may
experience difficulties in some locations – therefore you should
never rely solely upon your handset for essential communications in
emergencies.  (See your Ericsson User’s Manual for additional
important information.) 

Here’s a quick set of notes and troubleshooting tips:

If you have a weak signal or see the message “NO NETWORK” on
your handset display:

> If you’re inside a building, try moving close to an outside

window.

If the “KEYLOCK” message is displayed:

> Press the left 

C key, followed by F.  This will unlock

your keypad.

If the indicator light on top of your handset blinks red:

> Your battery is becoming exhausted and needs recharging or

replacing.  (See p. 17 for information.)

If your long distance call won’t go through:

> Remember to enter 

1 plus the area code if calling long

distance.
