I get extra characters at the beginning or end of my bar code data...
Clear the Preamble and Postamble settings.
I have very poor read rates when scanning bar codes...
Carefully follow the scanning instructions in Appendix M; How to scan a bar code when reading any and
all bar codes. As straightforward as scanning may seem, many people who call with a complaint about poor
read rates simply aren't doing it right.
Try reading the following bar code below as an example of a known “good” bar code. This bar code is a
Code 39 bar code and is readable by the RF Terminal set to its default settings.
Make sure your bar codes have clearly defined dark bars and clean white spaces. If the bars are so light
that they are gray instead of black or are so dark that they “bleed” into the white spaces, the printing of
the bar codes is the problem. Whoever is printing the bar codes needs to make the necessary
corrections.
The bar code should also have a “quiet zone” of at least ¼” to the left of the first bar and to the right of
the last bar. Make sure the beam covers the bar code completely and “overscans” a bit on each end.
Check the laser beam window at the top of the unit and make sure it's not dirty or scratched.

If you have a problem…

If you have a problem with your RF System, consult the troubleshooting section of this manual
FIRST. As a last resort before calling for an RMA, you can perform a diagnostic reset on your terminal.
This resets everything back to the factory defaults, so be prepared to remake any setup changes (i.e.
Terminal ID) you had made prior to the reset.
At the SIGN ON prompt, press the F1 key and release it.
then press the SHIFT key and release it.
press the D key and release (you will now see a menu)
press the K key and release.
If you cannot find the answer here, or the diagnostic reset does not work, call your Dealer or Worth Data
for help.
Save the shipping box. If you ever need to send the RF Terminal or any of its’ parts back for repair, use
this box.
Before you call your dealer or Worth Data for technical support, have your RF Terminal and related
