Laser Scanning Instructions
Using a laser scanner is basically as simple and intuitive as "point and shoot"
at a distance of 0-24", depending on the density of the bar code.
Basically, the laser scanner's beam must cross every bar and space on the bar
code, without touching any other bar codes, as shown in the first example
below. You'll need to hold the scanner further away to produce a wider beam
for large bar codes, and closer for bar codes with bars very close together.
Even though momentary exposure to a laser's low-power, visible-light is not
known to be harmful, you should not aim the beam into anyone's eyes.

When you scan, you will get one beep when you get a successful decode and a
high-pitched beep. The data is then transmitted to the Base Station (as it is
being transmitted, the LED flashes yellow). When the Laser receives the
acknowledgement from the Base Station that the data has been received, the
Laser emits a lower pitched beep and turns on a green LED for three seconds.
If the transmitted data fails to be acknowledged,
1) further scanning is prohibited. You can't pull the trigger again
until the data reaches the base or until you clear the scanner.
2) The laser will retransmit three times, (the yellow LED will
indicate retransmissions).
3) If it fails three times, it will emit a distinct 8-beep pattern and
turn off. This is your clue to check out the Base Station.
4) You can pull the trigger to try transmission again. (the laser beam
will not come on until the transmission is acknowledged or you
hold the trigger down for 30 seconds to clear the data).

The important thing to remember about using a laser with the RF Laser Reader
Setup Menu is that you need to make sure the scanner's beam covers only one
bar code at a time. The laser scanner's beam is wide enough, and the
configuration bar codes close together enough, that you will need to use your
fingers, post-it notes, or the supplied Laser Setup Assist window, to "block
off" bar codes adjacent to whatever configuration bar code you need to read.
