The unit powers 
up, but does not 
beep when bar 
code is scanned. 

The beeper is 
disabled and no tone 
is selected. 

Enable the beeper and select a 
tone. 

 

The unit powers 
up, but does not 
scan and/or 
beep. 

The bar code 
symbology trying to 
be scanned is not 
enabled. 

UPC/EAN, Code 39, interleaved 2 
of 5, Code 93, Code 128, Codabar 
and PDF are enabled by default.  
Verify that the type of bar code 
being read has been selected. 

 

The unit powers 
up, but does not 
scan and/or 
beep. 

The scanner is trying 
to scan a bar code 
that does not match 
the configured 
criteria. 

Verify that the bar code being 
scanned falls into the configured 
criteria (i.e. character length lock or 
minimum bar code length settings).

 

The unit scans 
a bar code, but 
locks up after 
the first scan 
and the white 
LED stays on. 

The scanner is 
configured to support 
some form of host 
handshaking but is 
not receiving the 
signal. 

If the scanner is setup to support 
ACK/NAK, check to make sure the 
host is supporting the 
handshaking properly. 

 

The unit scans, 
but the data 
transmitted to 
the host is 
incorrect. 

The scanner’s data 
format does not 
match the host 
system requirements. 

Verify that the scanner’s data 
format matches that required by 
the host.
