3.7.3 Audio Indicators
The 8515 beeper provides a variety of sounds and can be configured to emit a sound when a
key is pressed, a keyboard character is rejected, scan input is accepted or rejected or an oper-
ator’s entry does not match in a match field.
3.8 Scanning
Decoded scanners must be configured by scanning special configuration bar codes. In these
cases, the scanner manufacturer provides programming manuals for configuration purposes.
The 8515 supports a variety of one dimensional (1D) scanners and two dimensional (2D)
laser and imager scanners.
“Scanning Techniques” outlines the mechanics of a successful
scan. In addition, “Troubleshooting” on page 42 provides some helpful suggestions should
the scan fail.
3.8.1 Scanning Techniques
• Hold the scanner at an angle. Do not hold it perpendicular to the bar code.
• Do not hold the scanner directly over the bar code. In this position, light can reflect back
into the scanner’s exit window and prevent a successful decode.
• Scan the entire bar code. If you are using a 1D or 2D scanner, make certain that the scan
beam crosses every bar and space on the bar code, including the margins on either end
of the symbol.
• If you are using a 2D imaging scanner, make certain the red, oval-shaped framing mark
is centered within the bar code you want to scan.
• When using imaging scanners, do not move the scanner while decoding the bar code.
Movement blurs the image.
• Hold the scanner farther away for larger bar codes.
• Hold the scanner closer for bar codes with bars that are close together.
3.8.2 Scan LED Indicators
External scanners have integrated LED indicators that are not controlled by the 8515.
Note: Refer to “Volume And Sound Properties” on page 81 for details about the Vol-
ume & Sound Properties dialog box.
Note: External scanners can be connected to the 8515 serial or USB device port.
