Power on, power-on self-test, and power off
When the battery is charged, press
to turn on the monitor.
The monitor runs a diagnostic self-test each time it powers up.
•
If all tested functions are working normally, the various windows briefly display
start-up values (‘8’ and ‘- -’) and a short tone sounds twice.
•
If the self-test fails, an error code appears in the SYS window.
When the self-test is complete, the software version appears briefly in the message
window, followed by the current time of day.
To shut off the monitor, press
.
Caution Users should check for audible alarm function every time the VSM 300
is used. During the normal power-up cycle, two audible tones are emitted
immediately after the self-test is complete. If these tones do not sound, the audio
has failed. Remove the device from service and contact Welch Allyn.
The loss of the audible alarm could cause a delay in a clinician learning of an alarm
condition for the following conditions: 1) hypotension or hypertension, 2) low
blood oxygen content (SpO
2
), 3) low or high pulse rate, 4) other alarm conditions
relating to the loss of monitoring of a patient (e.g., a “sensor off” condition). Such
delay could potentially result in injury to the patient.
Caution Always observe the monitor during power-up. If any display fails to
illuminate properly, or if an error code appears in the systolic window, inform your
biomedical engineering department immediately, or call your nearest Welch Allyn
Customer Service or Technical Support facility. Do not use the monitor until the
problem is corrected.
Note
Shutting off the monitor erases all stored patient data but does not erase settings
or configuration parameters.
