The Beeper
The portable provides audible feedback to indicate when a bar code has
been scanned successfully and to acknowledge when a key is pressed.
The default setting provides one beep to indicate a good scan or key
entry. Another beep sequence warns of possible problems. The pitch,
number, volume, and length of beeps are all programmable.
