Troubleshooting 

All Models Troubleshooting 

The beam won’t stay on, or I just get a narrow beam when I pull the 
trigger, or The scanner won’t turn on when I pull the trigger and I get 3 
beeps 

• 

All of the above problems are an indication that your BATTERIES 
ARE TOO LOW. With any of the above symptoms, change to known 
good batteries before assuming you have some other kind of problem. 
Also, make sure the batteries are inserted CORRECTLY – batteries 
won’t work if they are not inserted in the right direction. See page 51 
concerning changing batteries and the correct battery orientation. 

 

The reader won't beep when reading bar codes 

• 

Recheck all the connections. Get close to the Base Station. Try reading 
the Link Test bar code, following the steps for scanning on pages 10-11. 

 

• 

If you hear two beeps, but see nothing on the screen, and you are 
reading the pocket card, you must read the ENTER bar code to have 
anything transmitted. Any Code 39 or 128 bar code with leading spaces 
(such as the Barpad on page 28) will not be transmitted to your 
computer until you read a bar code without a leading space.  Try 
reading the Test Label on page 25 as an example of a known good label 
without a leading space.  If you have bar codes with leading spaces in 
them, and you want them transmitted, you must disable Accumulate 
Mode using the Setup Menu. 

 

• 

Reread the configuration section and make sure you properly enabled 
the bar code types you're trying to read. 

 

Extra characters at the beginning or end of your bar code data 

• 

Clear the Preamble and Postamble.   

 

Poor read rate 

• 

Get close to the Base Station and try reading the test label on page 25 
(following the scanning instructions on pages 10-11) as an example of a 
known good bar code.  Examine your bar codes to make sure they have 
dark bars, clearly defined bars and white spaces, and a "quiet zone" of 
at least 1/4 inch to the left and right.  If the bars are gray, or so dark that 
they "bleed" into the white spaces, the person or organization printing 
them will need to adjust the printer or get a new ribbon or toner 
cartridge for it.  

 

I get six beeps when the One-Way Base Station powers up or six flashes 
on the 2-way Base Station. 

• 

The unit needs repair. Call for an RMA.
