Laser Test – All bar codes scanned will be echoed to the display (if this test
was selected from the keypad) or to the comm line (if this test was selected
from the comm line). When a bar code is scanned, the decoded data appears
on the top line of the display. The bottom line of the display will indicate the
type of code read (ie – Code 3 of 9) and the type of scanner used (laser or
wand). If an error occurs, any one or all of the three following errors may
appear on the second line of the display:
LRC error!
N Parity errors!
Timeout!
Press <EXIT> to terminate the test.
2–Display Test
If <ENTER> is pressed while 2–Display Test is on the display, the display
test will be activated. All characters that can possibly be displayed will be
displayed.
This test repeats indefinitely until the <EXIT> key is pressed.
Press <EXIT> to terminate the display test.
3–Destructive RAM Test
Note: This RAM test is identical to the test which is run when the
workstation is reset to factory defaults.
The third diagnostic is a destructive test of all RAM. Since selecting this
test will reset the workstation, the following message is displayed before the
test is started:
Unit will reboot
after test
Enter to start
Clear to quit
If you do not want to run this test, press <CLEAR>, which will cause
3–Destructive RAM Test to be displayed. Pressing <EXIT> will then return
to the Network Menu selection point.
