SCANNER OPERATION
INDICATOR DESCRIPTIONS
AudibleWhen the MS7820 scanner is in operation, it provides audible feedback. Thesesounds indicate the status of the scanner. Eight settings are available for thetone 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 forthe 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 thescanner does not beep once and the blue LED does not flash, thenthe bar code has not been successfully read.
Two Beeps
The scanners programmed interface setting does not match theactual connected interface cable. This audible indicator will beheard during power up, or when a bar code is scanned.
Razzberry Tone
This is a failure indicator. Refer to failure modes on page 34.
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 willstop 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 thesingle configuration bar code has successfully configured thescanner.
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 34.

SCANNER OPERATIONPOWER SAVE MODES
The MS7820 bar code scanner has five configurable power save modes. Referto the MetroSelect Configuration Guide for additional information on Power Save
Modes.
1.

Blink Power Save Mode:“Blinks” the laser OFF & ON after a configured period of non-use.
When the scanner recognizes a bar code, it will exit the Blink mode.

2.

Laser Off Power Save Mode (Default):
Turns the laser OFF after a configured period of non-use.
The motor continues to spin allowing for a faster “wake” up time. Pressing
any of the three buttons will “wake” the scanner from the Laser Off powersave mode (see figure 17).

3.

Laser & Motor Off Power Save Mode:
Turns the laser and motor OFF after a configured period of non-use.
Pressing any of the three buttons will “wake” the scanner from the powersave mode (see figure 37). This mode’s “wake up” time is slightly longer due
to the motor’s need to restart.
