Note: If you are out of range when you scan a bar code, you will receive an error beep even if you do not have the alarm set. You receive the error beep since the data could not be communicated to the base or the host.

If you have set the out-of-range alarm enabled, you may change the alarm type for the scanner or base by scanning the appropriate bar code below and then scanning a digit (0-7) bar code and the Save bar code on the Programming Chart inside the back cover of this manual. Default = 0. Set the sound type to fit your application.
