4-10 Chapter 4: Operating Your Scanner
Read Indicators
Your RealScan 7892 provides two methods of indicating valid reads:
Status Indicator (visual) and Audible Tone. The Status Indicator is
always enabled; however, you can disable the audible tone.
Status Indicator
The Status Indicator light is located on the top of the scanner. When the
RealScan 7892 detects bar code data, the laser turns on and the Status
Indicator turns red. When an accurate read of a valid bar code occurs,
the Status Indicator turns red until the bar code is removed; it then
turns green again.
When using IBM 468x communications, the Status Indicator flashes red
(group of nine flashes repeated at 3-second intervals) when the
RealScan 7892 is offline. This can be caused if the IBM host terminal
has not established communications with the RealScan 7892, the host
terminal is not turned on, or the interface cable is not connected.
Audible Indicator
You can program a "Good Read" tone that indicates the scanner's
ability to accurately read bar codes. This permits you to identify good
reads without having to observe the Status Indicator. No tone is
generated if the scanner does not detect a valid bar code.
