Order replacement cables from unitech or from an authorized distributor.

Replacing an Interface Cable
1. Turn the power to the host system OFF.
2. Disconnect the scanner’s cable from the
terminal or computer.
3. Locate the small hole on the back of the
scanner’s handle. This is the cable release.
4. Straighten one end of a paper clip.
5. Insert the end of the paper clip into the small
hole and press in. This depresses the retention
tab, releasing the connector. Pull the connector
out while maintaining pressure on the paper clip,
then remove the paper clip.
6. 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.
Troubleshooting a Unitech MS832 Scanner
The scanner automatically performs self-tests whenever you turn it on. If your scanner is not
functioning properly, review the following Troubleshooting Guide to try to isolate the problem.
Is the power on? Is the aimer on?
If the aimer isn’t illuminated, check that:
‧
The cable is connected properly.
‧
The host system power is on (if external power isn’t used).
‧
The button works.
Is the scanner having trouble reading your symbols?
If the scanner isn’t reading symbols well, check that the scanner window is clean and 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 scanner or in the decoder to which the scanner connects.
Is the bar code displayed but not entered?
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).
