$ Do not stare into the laser
beam or point the scanner at any-
one's eyes. Eye damage could occur.
See the instructions provided
by your organization for the
recommended scanning distance.
If your PTC has a backlight, it may
be programmed to blink off during
scanning operations to conserve
power.

Make sure the scan line extends
beyond both sides of the bar code
Follow this procedure to scan bar-code labels if your
PTC is equipped with an external laser scanner.
1. Point the laser scanner at the label to be scanned.
The scanner can be at an angle to the label. The
maximum distance from the window on the nose
of the scanner to the label depends on whether
you have a short-range or long-range bar-code
scanner and on the size of the label being scanned.
2. Press the trigger on the scanner to start scanning.
Your scanner may have a light or other indicator
to let you know it is scanning.
3. Watch the line of light made by the scanner as it
scans the bar code. The line must pass over all of
the bars on the label for the bar code to be read.
See Figure 5.
If the scan is successful, the PTC may beep or
inform you in some other way, depending on your
application program. The scanner may also have
a light that glows to indicate a successful scan.
See the scanner's manual for details.
