Operational Modes
Product Reference Guide 3-7

Error Reporting

If a fatal error is detected during Selftest or operation, the unit will not
advance to Normal Operation Mode. Selftest diagnostics will cause the
unit to sound a long, low tone and/or display an error message on the 7-
segment display indicating where the failure occurred. These messages are
coded to assist the repair technician in identifying the failed component.
If the error is with the EAS deactivation system, the bottom-most LED
will flash red. If an error is indicated, make note of it and contact your
supervisor or technical support representative. A table containing descrip-
tions of these error codes is included in Chapter 4, Problem Isolation.
If a non-fatal1 error is detected (such as the loss of one of the two lasers, or
EAS deactivation system error), the unit will sound a long, low tone and
display a number on the 7-segment display. The unit will advance to Nor-
mal Operating Mode, but performance may be affected until a correction
or repair is made.

Operational Configuration

Once Selftest diagnostics have been successfully run, a tone is emitted (if
configured to do so, and the unit enters an operational configuration state.
The scanner or scanner/scale will automatically load your specific interface
settings which are required to communicate with the host system. There
are two conditions that must be met before the unit can enter Operating
Mode:
• No bar code label can be in the scan volume while the unit is in this
state. Progress is halted until the label has been removed, thereby
ensuring that no extraneous bar code data is send to the host.
• If your scanner has a scale, the scale cannot be in motion (usually
caused by excessive vibration in the checkstand) for this test to suc-
ceed. A “Scale in Motion” status will be indicated by displaying a
period and the applicable weight unit (lb or
kg ) that is selected.
• The scale must be able to “capture” zero weight. The
display will be seen if there is a weight on the platter at
power-up. Removing the weight or pressing the Scale Zero Push
Button should allow the scale to find zero.

ming for more details.
