Problem
The following message is displayed on the Head Unit LCD:
FLASH STATUS:
FAILED
Solution
Power the unit down and back up. If after powering the unit back up, the same
message is displayed, contact your vendor for support.
---------------------------/---------------------------
Problem
The following message is displayed on the Head Unit LCD:
RFID STATUS:
INIT. FAILED
Solution
If you have purchased a unit that only has a Fingerprint Scanner and Keypad
installed, with no RFID module, this message is normal.
If you have purchased a unit with RFID, there is a problem with the Head Unit
microcontroller communicating with the RFID Module. It's possible that the cable
inside the Head Unit that connects the main PCB to the RFID Module was disturbed
during installation. The cable should be attached to the connector located at the left
edge of the main PCB inside the Head Unit and is labeled "RFID". Power the unit
down and check this cable is properly seated at both ends.
If after powering the unit back up, the same message is displayed, contact your
vendor for support.
---------------------------/---------------------------
Problem
When the unit is powered up for the first time, the LCD display is blank.
Solution
Try pressing 0 (zero) on the Head Unit keypad. The contrast may have been set very
low, making the characters invisible.
---------------------------/---------------------------
Problem
The Control Unit powers up but the Head Unit does not.
