TROUBLESHOOTING

Omnipoint services are 100% digital, so they’re more reliable than conventional cellular phone service.

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 Ckey, 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 1plus the area code if calling long distance.

If you have a poor connection:

>The problem may be at the other end; press Gto 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.
