OPERATIONAL NOTES
Metrologic recommends using the external power supply provided with the
scanner when operating the MS7120. When using power supplied by the host,
the host system should supply a minimum of 250 mA of current @ 5VDC.
Orbit is shipped from the factory programmed with default settings. To configure
the MS7120 scanner to meet the host system’s specific needs, refer to the
MetroSelect Programming Guide (MLPN 00-02407B) for instructions on how to
enter the program mode and select the appropriate bar codes.

Manufacturer’s Recommendation:
Powering Orbit directly from the computer can sometimes cause
interference with the operation of the scanner or the computer. Not all
computers supply the same current through the keyboard port, explaining
why a scanner will work on one computer and not another. Metrologic
recommends using an external power supply. For additional information
contact a Metrologic customer service representative.
Caution:
To maintain compliance with applicable standards, all circuits connected to the scanner must meet the
requirements for SELV (Safety Extra Low Voltage) according to EN 60950.

SCANNER PARTS
Red LED
On a successful read of a bar code, the red LED will turn ON.
After communication to the host is complete, the red LED will
turn OFF. Refer to Visual Indicators and Audible Indicators for
additional information.
Green LED
During normal operation, the green LED is ON. This indicates
that the laser is on and the unit is ready to scan. The LEDs are
also used as diagnostic indicators and mode indicators. Refer to
Visual Indicators and Audible Indicators for additional
information.

AUDIBLE INDICATORS
When the MS7120 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, refer to the MetroSelect®Programming Guide (MLPN
00-02407B) or the MetroSet2 help files.
One Beep
When the scanner first receives power, the green LED will
turn on, then the red LED will flash and the scanner will beep
once. (The red 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 red
LED will flash and the scanner beeps once (if programmed to
do so). If the scanner does not beep once and the red light
does not flash, then the bar code has not been successfully
read.
Razzberry Tone
This is a failure indicator. Refer to failure modes page 11.
Three Beeps - during operation
During operation of the scanner, the red LED will flash while
the scanner simultaneously beeps three times (while going
into programming mode).
The red LED will continue to flash until the unit exits program
mode. Upon exiting program mode, the scanner will beep
three times and the red LED will stop flashing. When
configured, 3 beeps can also indicate a communications
timeout during normal scanning mode. When using one-
code-programming, the scanner will beep three times (the
current selected tone), followed by a short pause then by a
high tone and a low tone. This tells the user that the single
configuration bar code has successfully configured the
scanner.
Three Beeps - on power up
This is a failure indicator. Refer to failure modes page 11.

10
VISUAL INDICATORS
There is a red LED and a green LED on the head of the MS7120. When
the scanner is on, the flashing or constant illumination of the LEDs
indicates the status of the current scan and the scanner.
No Red or Green LED
The LEDs will not be illuminated if the scanner is not receiving
power from the host or transformer.
Steady Green
When the laser is active, the green LED is illuminated. The
green LED will remain illuminated until the laser is deactivated.
During the power save mode, the laser will turn on and off.
During this period, the green LED remains illuminated.
Steady Green and Single Red Flash
When the scanner successfully reads a bar code, the red LED
will flash and the scanner will beep once. If the red LED does
not flash or the scanner does not beep once, then the bar code
has not been successfully read.
Steady Green and Steady Red
After a successful scan, the scanner transmits the data to the
host device. Some communication modes require that the host
inform the scanner when data is ready to be received. If the
host is not ready to accept the information, the scanner’s red
LED will remain on until the data can be transmitted.
Steady Green and Flashing Red
This indicates the scanner is in program mode. A razzberry
tone indicates that an invalid bar code has been scanned in
this mode.
Steady Red, Green off
This indicates the scanner may be waiting for communication
from the host.

11
FAILURE MODES
Flashing Green and One Razzberry Tone
This indicates the scanner has experienced a laser
subsystem failure. Return the unit for repair at an
authorized service center.
Flashing Red and Green and Two Razzberry Tones
This indicates the scanner has experienced a motor
failure. Return the unit for repair at an authorized service
center.
Continuous Razzberry Tone with both LEDs off
If, upon power up, the scanner emits a continuous
razzberry tone, then the scanner has an electronic
failure. Return the unit for repair at an authorized service
center.
Three Beeps - on power up
If the scanner beeps 3 times on power up then, the
nonvolatile memory that holds the scanner configuration
has failed. Return the unit for repair at an authorized
service center.

12
LABELS
Each scanner has three labels on the bottom of the unit. These labels
contain information such as; the model number, date of manufacture,
serial number, laser class and caution statements. The following
illustrations show the location and content of the three labels.
MAINTENANCE
Smudges and dirt can interfere with the proper scanning of a bar code.
Therefore, the output window will need occasional cleaning.
1. Spray glass cleaner onto lint free, non-abrasive cleaning cloth.
2. Gently wipe the scanner window.
