Head Unit Problems
Problem
The following message is displayed on the Head Unit LCD:
BASE STATUS:
CANNOT CONNECT
Solution
There is a communication problem between the Head Unit and Control Unit. The
most common cause of this is a cabling problem. Check the cable that connects the
Head and Control Units together. Ensure the cable is wired "straight-thru", i.e.
Terminal A on the Head is connected to terminal A on the Control Unit, terminal B is
connected to terminal B, etc.

Problem
The following message is displayed on the Head Unit LCD:
SCANNER STATUS:
INIT. FAILED
followed by
SCANNER STATUS:
'#' TO CONTINUE
Solution
There is a problem with the Head Unit microcontroller communicating with the
Fingerprint Scanner. It's possible that the cable inside the Head Unit that connects
the main PCB to the Fingerprint Scanner was disturbed during installation. The cable
should be attached to the connector located at the bottom left of the main PCB inside
the Head Unit and is labeled "Sensor". Power the unit down and check this cable is
properly seated at both ends.
