SCANNER OPERATION
INDICATOR DESCRIPTIONS
Audible
When the 7820 scanner is in operation, it provides audible feedback. These
sounds indicate the status of the scanner. Eight settings are available for the
tone of the beep (normal, 6 alternate tones and no tone). To change the tone,
use the Tone Button or refer to the MetroSelect Configuration Guide.
One Beep
When the scanner first receives power, the blue LED will turn on
and the scanner will beep once. The blue LED will remain on for
the duration of the beep. The scanner is now ready to scan.
When the scanner successfully reads a bar code, the blue LED will
flash and the scanner will beep once (if configured to do so). If the
scanner does not beep once and the blue LED does not flash, then
the bar code has not been successfully read.
Two Beeps
The scanners programmed interface setting does not match the
actual connected interface cable. This audible indicator will be
heard during power up, or when a bar code is scanned.
Razzberry Tone
This is a failure indicator. Refer to failure modes on page 35.
Three Beeps - during operation
When placing the scanner in program mode, the blue LED will flash
while the scanner simultaneously beeps three times. The blue LED
will continue to flash until the unit exits program mode. Upon exiting
program mode, the scanner will beep three times and the LED will
stop flashing.
When configured, three beeps can also indicate a communications
timeout during normal scanning mode.
The scanner will beep three times in an ascending tone, with each
beep higher in pitch than the previous. This tells the user that the
single configuration bar code has successfully configured the
scanner.
Three beeps will also occur during a manual adjustment of the
beeper tone. The scanner will emit three evenly pitched/spaced
tones with the blue indicator LED blinking in unison.
Three Beeps - on power up
This is a failure indicator. Refer to failure modes on page 35.
