Initializing the Scanner

Important: This procedure clears all infor- mation you stored in the scanner's memory. Initialize the scanner only when you are sure the scanner is not working properly.

1.Turn off the scanner, then turn it on again.

2.Hold down MON/CL.

3.While you hold down MON/CL, insert a pointed object, such as a straightened paper clip, into the RESET opening on the back of the scanner and gently press then release the reset button inside the opening. The display should clear.

4.When the display reappears, release

MON/CL.

Note: You must release the reset button before you release MON/CL, otherwise the memory might not clear.

CARE

Keep the scanner dry; if it gets wet, wipe it dry immediately. Use and store the scanner only in normal temperature environments. Handle the scanner carefully; do not drop it. Keep the scanner away from dust and dirt, and wipe it with a damp cloth occasionally to keep it looking new.

Modifying or tampering with the scanner’s internal components can cause a malfunction and might invalidate its warranty and void your FCC authorization to operate it. If your scanner is not performing as it should, take it to your local RadioShack store for assistance.
