When you have linked the modules, they can talk with each other up to 20
feet apart.
NOTE: When you are not using the printer, terminal, and RF link device,
be sure to turn them off.
Scanning Bar Codes
To scan a bar code:
1. Point the scanner at a slight angle approximately 4 – 8 inches from
the bar code symbol.
2. Pull the trigger until you hear a beep, which indicates a complete
scan. If you let go of the trigger before the beep, the scan stops
immediately.
CAUTION: Do Not stare into the beam.
If the bar code does not scan:
Change the angle of the scanner slightly and try again.
Clean the scanner window.
Move the scanner 4 – 8 inches away from the bar code. Adjust this
distance as needed to find the correct distance.
Try scanning another bar code that you have scanned successfully. If
that scan is successful, the scanning problem is with the bar code.
Move to a more dimly lit area.
Be sure there are no voids in the bar code symbol.
