Installation Overview
Product Reference Guide 2-21
When power is applied to the unit, the normal indicator sequence is:
• The scanner indicator (top-most, green LED) will be lit (dim)
steadily.
• The EAS indicator (bottom-most, tri-color LED) will flash ON/
OFF during power-up. Additionally, the 7-segment display will
flash the number ‘9’. indicating the EAS system is being initialized.
• If the Selftest detects a problem, the 7-segment display will display a
number code. Refer to
Chapter 4, Problem Isolation, for a descrip-
tion of failure codes and problem isolation procedures.
4. The unit should be permitted to reach thermal equilibrium before
proceeding to the next steps. (Reference the topic
Warm-Up Time in
Chapter 1.) When the unit is moved from a cooler temperature
(such as a storage area) to a warmer environment (such as a check-
stand location), a period of 60 minutes must be allowed to acclimate
the unit to ambient conditions. Once installed and powered up, a
“power-up” warm-up period of 15 minutes must be allowed before
calibrating or performing weighing operations. These two warm-
up periods may run concurrently.
5. Verify that the scanner or scanner/scale passes an operational test by
observing the following:
NOTE
Scale calibration may be necessary to obtain a zero reading on the display on
rare occasions.
