Welch Allyn 6000 Series - Power-Up Sequence

Power-up sequence
The monitor performs a power-on self test (POST) each time the device is powered on. During
power up, the monitor performs a comprehensive self test of the software. If software testing is
successful, the monitor then tests internal hardware. If all tests are successful, the monitor
completes power up and the Home screen appears.
To perform the POST:
1. Disconnect any patient cables connected to the monitor.
2. Insert a fully charged battery into the monitor.
3. Upon each power up, confirm the following:
a. The light bar flashes red then amber.
b. The Welch Allyn startup screen appears.
c. A beep sounds, followed by two chimes.
Note If no chimes sound, replace the speaker as specified in
“Remove the speaker.”
d. The product line logo appears at the bottom of the screen.
e. If a printer is installed, the paper advances slightly.
f. The Home screen appears.
WARNING Equipment failure risk. The monitor includes a fan that circulates air
through the device. If the fan does not run when you power up the device, remove it
from use and inform qualified service personnel immediately. Do not use the
monitor until the problem is corrected.
If the internal self-check is successful, the monitor shows its normal functions with all values blank
and the monitor is ready for operation. If the self-check fails, an error message appears in the
monitor status area at the top of the screen. If a fault that could adversely affect the product is
detected, the device enters a safe mode and stops monitoring patients. The device remains in safe
mode until it is turned off by pressing the Power button or until it shuts down automatically after a
period of inactivity.
If a system error is detected, the monitor becomes inactive until you press or until the monitor
shuts down automatically. The monitor displays a system fault message that contains a wrench
icon( ) and a system fault code to aid service and engineers in diagnosing the problem.
While in safe mode, the red LED bar and the piezo buzzer cycle on and off.
