The PTC's screen is slow to refresh (non-freezer units only)

•
Wait until the PTC warms up if it has been stored
or used in the cold.

The laser scanner does not read a label

•
Make sure the scanner's connector is firmly
attached to the PTC's scanner connector.
•
Make sure the bar-code label you are trying to scan
is one of the bar-code types your PTC has been
programmed to recognize.
•
Move the laser scanner closer to or farther away
from the bar-code label. You may not be scanning at
the correct distance.
•
Change the angle of the laser scanner to the
bar-code label. You may be too far above or below
the bar-code label or too far to the side to scan
properly.
•
Clean the scanner's lens with a soft cloth.
•
Point the scanner at a blank surface and press the
scanner trigger. Look for the scanning line that
appears on the blank surface when the scanner is
operating. If no scanning line appears, follow your
organization's procedure to have the scanner
serviced.

Your radio fails to establish contact

•
Change your location by a few feet and transmit
again.
•
Make sure the antenna is securely attached.
•
Check the PTC's vehicle or AC power connection.
•
Make sure the receiving equipment is turned on
and is properly connected to the host computer.
•
If the PTC still does not establish contact, follow
your organization's procedure to have the PTC
serviced.
