SYMPTOM: When I scan a lot of bar codes very fast, the scanner 
locks up and won’t work for a few seconds. 
POSSIBLE REASONS  SOLUTION 
You are scanning too fast for 
the Error Proof Protocol to 
confirm that the mobile 
computer has successfully 
received each scan of data. 
Wait for the confirmation beep 
after each scan before you scan 
a new bar code. You may need 
to re-scan data that was not 
correctly received by the mobile 
computer. 
SYMPTOM:  My mobile computer cannot find the Cordless Hand 
Scanner, and/or I get an error message saying that there are 
connection problems. 
POSSIBLE REASONS  SOLUTION 
You are too far from the 
Cordless Hand Scanner.  
Move the devices closer 
together, within a range of 10-
15 meters. 
The Cordless Hand Scanner is 
not turned on. 
Turn on the Cordless Hand 
Scanner. 
You have assigned another 
device as your favorite or 
default Bluetooth serial device. 
Remove any settings that assign 
another device as your favorite 
Bluetooth serial device. 
You are using an XP or Vista 
system without Connect!Agent, 
and you did not start the 
Bluetooth software. 
Start the Bluetooth software. 
The Bluetooth radio of your 
mobile computer is not turned 
on. 
Turn on the Bluetooth radio of 
your mobile computer.
