“Tall” PDF Bar Codes

If the PDF417 symbol is “tall,” the vertical scan pattern may not be high enough to cover it.
In this case, try a slow “up and down” scanning motion. With the raster pattern open, move
the terminal slowly down toward the bottom of the symbol, keeping the beam horizontal to
the rows, then slowly back up toward the top.
Figure 2-10. Scanning Tall PDF Bar Code
The scan beam does not have to be perfectly parallel with the top and bottom of the symbol
(up to a 4o tilt will work).
Resetting Your PPT 2700 Terminal
If your PPT 2700 terminal stops responding to input from buttons or the screen, you must
reset it by performing a warm or cold boot.

Performing a Warm Boot

A warm boot restarts the terminal and saves all stored records and entries.

Caution

Files that remain open during a warm boot may not be retained.
