Follow these steps to ensure that your unit has arrived undamaged and is
fully functional before installing it in the counter and connecting it to
your POS system.
1. If the unit is a scanning-scale, connect the Remote Scale Display
to the proper connector on the unit’s connector panel (refer to
Figure 2-13). Note that if the Remote Scale Display is not con-
nected, a scanner power-up Selftest will sound a long, low beep,
and the number “8” will appear on the 7-segment display indicat-
ing a remote display error. Power-down, connect a known-good
Remote Display to the appropriate port, and restart to correct this
problem. Alternatively, you can disable the Remote Display using
programming bar codes (see Section 6, Programming for more
information).
2. Connect the power cable at the scanner then at the AC outlet.
When power is applied to the unit, the normal indicator sequence is:
• The green light will be lit (dim) steadily.
• If the Selftest detects a problem, the 7-segment display will dis-
play a number code. Refer to Section 4, Problem Isolation, for a
description of failure codes and problem isolation procedures.
3. The unit should be permitted to reach thermal equilibrium
before proceeding to the next steps. (Reference the topic Warm-
Up Time in Section 1.) When the unit is moved from a cooler
temperature (such as a storage area) to a warmer environment
(such as a checkstand 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 weigh-
ing operations. These two warm-up periods may run concur-
rently.
NOTE
Scale calibration may be necessary to obtain a zero reading on the display
on rare occasions.
