AutoSense
®
Operation
AutoSense ® is a factory installed feature requested at time of order. It
provides for hands-free or handheld operation. AutoSense
®
is acti-
vated by scanning the Enable AutoSense
®
symbol. The scanner will
respond by emitting a continuous, low level red beam of light known
as the trigger beam. AutoSense
®
is deactivated by scanning the Dis-
able AutoSense
®
symbol.
When the AutoSense
®
feature is used with PSC’s AutoSense
®
stand
(specifically designed for standard and HP scanners), the user must
first attach the plastic scanner holder to the bracket of the stand as
shown in Figure 1, next page. The scanner is then mounted into the
holder. Insure that the trigger beam is aimed at the reflective tape
affixed to the stand. AutoSense
®
is now ready to automatically scan
bar code labels presented to it. When the trigger beam is broken by
the bar code label, the scan beam will automatically engage and
decode the bar code symbol. Any time the scan beam disappears,
whether by a decode or by a scan beam timeout, the automatic trigger
must be re-enabled by allowing the trigger beam to sense the reflec-
tive tape.
While AutoSense
®
is activated, the user is able to remove the scanner
from its holder and use it for handheld scanning operation. When the
scanner is removed from the AutoSense
®
holder, the trigger beam
will be broken and the scan beam will automatically be engaged. If
the scanner does not decode a bar code symbol, the scanning beam
will turn off after two to six seconds. Scanning is re-initiated by man-
ually pulling the trigger. When the scanner is replaced into the holder
AutoSense
®
will be automatically re-engaged when the trigger beam
senses the reflective tape.
NOTE
When the scanner is powered from a battery, such as in a
hand-held terminal, AutoSense
®
should be disabled. In a
battery powered application, the user is strongly recom-
mended to use the power conservation feature of scan-
ner operation. Power conservation reduces power draw
from the battery between scans to extremely low levels.
AutoSense
®
will function only in full power mode.
