Which items are included in the Built-In Test (BIT)?

• A. Operational test, battery check, display firmware and hardware versions
• B. Operational test only
• C. Battery check only
• D. Display firmware and hardware versions only

Answer: (A)

Built-In Test checks the device’s essential subsystems at startup to confirm it’s ready for use. It includes three elements: an operational test that exercises core functions to verify the hardware and software respond correctly; a battery check to ensure the power source is within safe limits and capable of sustaining operation; and a check of the display subsystem, covering both firmware and hardware versions to confirm the display is functioning and compatible with the system. Together, these ensure the device can operate, remains powered, and presents information correctly. Leaving out any one of these would mean a fault could be present that impedes use, whereas the other options miss one or more of these crucial checks.
