Maintenance
Maintenance
Repairs and/or upgrades are not to be performed on this product.  These ser-
vices are to be performed only by an authorized service center.  See 
Customer Support on page 13-1 for further information.
Cleaning the Device
Reading performance may degrade if the image scanner’s window is not clean.  
If the window is visibly dirty, or if the image scanner isn’t operating well, clean 
the window with a soft cloth or lens tissue dampened with water (or a mild 
soapy water solution).  If a detergent solution is used, rinse with a clean lens tis-
sue dampened with water only.
The base and image scanner’s housing may also be cleaned the same way.
Inspecting Cords and Connectors
Inspect the base’s interface cable and connector for wear or other signs of dam-
age.  A badly worn cable or damaged connector may interfere with image scan-
ner operation.  Contact your distributor for information about cable replacement.  
Cable replacement instructions are on page 12-2.
!Caution:
Do not submerge the image scanner in water. The image 
scanner’s housing is not watertight. 
Do not use abrasive wipes or tissues on the image 
scanner’s window – abrasive wipes may scratch the 
window.  Never use solvents (e.g., alcohol or acetone) on 
the housing or window – solvents may damage the finish 
or the window.

Replacing the 2020 Interface Cable:
1. Turn the power to the host system 
OFF.
2. Disconnect the base’s cable from the 
terminal or computer.
3. Turn the base upside down.
4. Pull the connector out while 
maintaining pressure on the 
connector release clip.
5. Replace with the new cable.  
Insert the connector into the opening 
and press firmly.  The connector is 
keyed to go in only one way, and will 
click into place.
Changing the 3820/3820i 
Battery:
1. Remove the screw on the end 
cap on the 3820.  On the 
3820i, unscrew the thumb-
wheel end cap.
2. Remove the battery from the 
handle.
3. Insert battery.
4. Replace end cap and screw or 
tighten the thumbwheel end 
cap.
Troubleshooting 
Base
Note: Please visit the Services and Support section of our website 
(www.honeywellaidc.com) to check for the latest software for both the 
image scanner and the base.
If your base is not functioning properly, review the following troubleshooting 
guidelines to try to isolate the problem.
Is the red LED on? 
If the red LED isn’t illuminated, check that:
End Cap 
						

							12 - 3
 The power cable is connected properly and there is power at the power 
source.
 The host system power is on (if external power isn’t used).
Is the green LED on? 
If the green LED isn’t illuminated, check that:
 The image scanner is correctly placed in the base.
 There is external power or 12 volt host power.
 Charge mode is turned on.  (See  Base Charge Mode on page 1-4)
 The battery is not bad or deeply discharged.  In some cases, the image 
scanner’s battery may trickle charge to bring it into an acceptable level and 
then transition to a normal charge cycle.
Troubleshooting the Image Scanner
Note: Make sure that your image scanner’s battery is charged.
Note: Please visit the Services and Support section of our website 
(
www.honeywellaidc.com) to check for the latest software for both the 
image scanner and the base.
Is the image scanner having trouble reading your symbols?
If the image scanner isn’t reading symbols well, check that the symbols:
 Aren’t smeared, rough, scratched, or exhibiting voids.
 Aren’t coated with frost or water droplets on the surface.
 Are enabled in the base to which the image scanner connects.
Is the bar code displayed but not entered into the application?
The bar code is displayed on the host device correctly, but you still have to press 
a key to enter it (the Enter/Return key or the Tab key, for example).
You need to program a suffix.  Programming a suffix enables the image scanner 
to output the bar code data plus the key you need (such as “CR”) to enter the 
data into your application.  Refer to Prefix/Suffix Overviewon page 4-1 for fur-
ther information.
Does the image scanner read the bar code incorrectly?
If the image scanner reads a bar code, but the data is not displayed correctly on 
the host screen:
 The base may not be programmed for the appropriate terminal interface. 
For example, you scan “12345” and the host displays “@es%.”
Reprogram the base with the correct Plug and Play or Terminal selection bar 
code.  See Chapter 1 and Chapter 2.
 The base may not be programmed to output your bar code data properly.
For example, you scan “12345” and the host displays “A12345B.”
Reprogram the base with the proper symbology selections.  See Chapter 6. 
						

							12 - 4
The image scanner won’t read your bar code at all.
1. Scan the sample bar codes in the back of this manual.  If the image scanner 
reads the sample bar codes, check that your bar code is readable.
Verify that your bar code symbology is enabled (see Chapter 6).  
2. If the image scanner still can’t read the sample bar codes, scan All 
Symbologieson page 6-1.
If you aren’t sure what programming options have been set in the base, or if you 
want the factory default settings restored, scan Resetting the Standard Product 
Default Settings: Current Application Work Groupon page 10-4.
Troubleshooting the Cordless System
The image scanner must be linked to the base for the system to work properly.  
See  Linking Image Scanner to Base on page 1-5.
