the seven-segment display, indicating the current test being run. See
IMPORTANT:
After a power failure or shutdown, the system automatically returns to last powered state (On or Off)
when A/C power is restored.

Ensure that the Power On/Standby button was pressed firmly and held for approximately three
seconds.
2. Verify that the Power button/LED on the UID module is green.
