Magellan
TM
8500Xt Scanner
Pressing and holding the Volume/Tone Push Button for approximately
eight seconds initiates a reset, which is sounded by a rapid number of
beeps. If the motor had been spinning, the lamps will blink while the
motor spins down. At that point, the motor will spin back up and the
scanner will continue to run the Selftest diagnostics. For more informa-
tion, see the topic,
Power-Up/Selftest & Pre-Operation
earlier in this section.
Scale Adjustments
The scale allows two user adjustments: zeroing and calibration. The first,
and most frequently performed, is ‘zeroing’ the scale. This operation resets
the scale’s “at rest” reading to zero which must be within the range of - 0.2
pounds (- 1.25 grams) to +0.6 pounds (0.27kg) since the last calibration.
While the ‘at rest’ reading remains within the zero range, the scale will
automatically adjust itself to true zero. The scale also automatically zeros
itself on power-up if the weight present on the scale is within these defined
limits.
Zeroing the Scale
The zeroing operation may be performed by checkers and other store per-
sonnel. Pressing and releasing the Scale Zero Push Button should return
the scale to Normal Operation. If the zero point moves out of the zero
range due to debris accumulation or other causes, pressing the Scale Zero
Push Button will not reset the zero point. In this case the weigh platter
must be cleaned, debris chutes cleared of debris or the scale must be recal-
ibrated.
With the scanner/scale powered-up and at operating temperature:
1. Remove everything from the weighing surface of the scanner/
scale.
2. Press the Scale Zero Push Button. (See
Figure 1-1
).
3. The Zero
1
light will turn on and the display will show 0.00 lb
(0.000 kg). If it does not, see
Chapter 4, Problem Isolation
.
4. You have completed the scale zeroing function.
1. Zero light operation is configurable.
