Troubleshooting
General Considerations
Site Test
The most basic tool for troubleshooting is the Site Test at 50 feet range. (See Chapter 4 for the details on
how to do a Site Test). If the Site Test fails at close range (50 feet), you have found the problem. The radio
on either the Base Station or the RF Terminal is defective. A Terminal may operate poorly at a distance of
less than 10 feet from the Base due to high transmitter power. Make sure to Site Test at least at 50 ft. range.
If you have multiple terminals and multiple Base Stations, after site test failure, you can determine if the
failure is with the Terminal or the Base by substitution. If you have only one Terminal and Base, you have
no way of knowing which has failed; you must call us and get an RMA for both units to be checked out at
the factory in Santa Cruz or in Ireland.
If the Site Test passes, there is nothing wrong with the radios.
Changing the Battery
For RF Terminals, the most frequent cause of problems is a low battery that has either been ignored or
undetected. The real test for the battery is to remove battery from a working unit and place it into a suspect
unit.
Most of the time the battery becomes the problem as a result of:
• The operator ignores the Low Batteries message and doesn’t finish up the transaction and immediately
charge the battery. If you turn the unit off and turn it on again, the battery may have had time to “almost”
recover. Unfortunately they will have so little reserve power that they will likely operate just long enough to
produce some very screwy behavior on the RF Terminal. Intermittent laser beams, continuous beeping, a
blank screen, etc. are just a few of the disastrous symptoms that can be exhibited.
Problems with a new installation:
“Waiting for Base to Acknowledge” is a normal message, generated when you first try to establish radio
contact. If your Terminal continues to generate this message and it ultimately results in a "Transmission
Failed" message, your radios are not communicating. Be sure they’re on the same channel and try again. If you
have multiple terminals, try another terminal. If the 2
nd terminal also fails on the same channel, the base station
is bad. If the 2 nd terminal passes the Site Test, the first terminal is bad.
If the Terminal displays the “Waiting on Host Prompt” message, the host program is not communicating with
the Base Station. There is no radio problem, because the Base Station has already acknowledged the Terminal’s
Sign In. The Terminal is waiting on the Host to tell it to do something. Try the demo program; if it works the
problem is your program.
If using the Active X program with XP, be sure "connection pooling" is disabled.
If the demo program fails, the problem is one of the following:
