TROUBLESHOOTING

If the phone’s power does not come on or stay on:

•Make sure the battery is properly installed and charged.

•Be sure the contacts on the battery are clean, If they are not, clean them with a soft cloth or pencil eraser.

•The battery charge might be too low for operation. Check the display and listen for the low battery warning tones.

If the power comes on, but the phone does not work:

•Make sure that the antenna is fully extended.

•Be sure you selected the correct cellular system type (see “Setting the Cellular System Type” on Page 46).

•Make sure that functions you might have previously selected (but forgotten) are not causing the phone to operate differently than you expect it to (see “Function Status Quick-Review” on Page 25).

•Check the display for error messages.

If you see an error message that is not covered in any section in this Owner’s Manual, or if your phone does not seem to be operating properly, contact your local RadioShack store for assistance.
