General Considerations
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 very inconsistent behavior on the RF Terminal. Intermittent laser beams, continuous beeping, a
blank screen, etc. are just a few of thesymptoms that can be exhibited.
Problems with a new installation:
“Searching Host Application” 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 "Host Application Timed Out"
message, your Terminal is not making a connection with the network. Make sure your Access Point and
Connection Host configuration is correct and try again. Make sure there is a properly configured Application
Server running. If you have multiple terminals, try another terminal. If the 2
nd
terminal also fails, then it is likely
there is something wrong with the configuration.
If the Terminal displays the “Waiting on Host Prompt” message, the Application Host program is not
communicating with the Connection Host. There is no radio problem, because the Connection Host has already
acknowledged the Terminal’s Sign In. The Terminal is waiting on the Host to tell it to do something. Try Worth
Data's demo Application Server; if it works then the problem is your program.
If the demo Application Server fails, the problem is one of the following:
• Your internet connection is down or busy. The demo Application Server is experiencing high traffic and is
busy.
