Power-up sequence
The device performs a power-on self-test (POST) each time it is powered on. During power-up, the
device performs a comprehensive self-test of the software. If software testing is successful, the
device then tests internal hardware. If all tests are successful, the device completes power-up and
the Home screen appears.
To perform the POST:
1. Insert a fully charged battery into the device.
2. Power on the device.
3. Confirm the following:
a. The backlight turns on.
b. The Welch Allyn startup screen appears, and the product line logo appears at the bottom
of the screen.
c. The Home screen appears.
If the internal self-test is successful, the device shows its normal functions with all values blank, and
the device is ready for operation. If a system error is detected, the device becomes inactive until
you press the power button or until the device shuts down automatically. The device displays a
system fault message that contains a wrench icon and a system fault code to aid service personnel
and engineers in diagnosing the problem.
