C. CANCEL Button
If a blood pressure cycle is in progress, pressing this button aborts the cycle and immediately
releases the cuff pressure. In "STAT" automatic blood pressure mode, pressing the cancel button
aborts the cycle in process, and cancels the "STAT" mode as well.
When pressed for 3 seconds, the cancel button erases all stored data in the Welch Allyn Vital
Signs Monitor.

sets.
E. AUTO Button & Indicator
Pressing this button allows the operator to scroll through the automatic blood pressure interval
options. Time intervals are displayed in minutes on the CYCLE display (see below). Choosing
any time interval except "--" will cause the Auto indicator light to glow, and blood pressure deter-
minations to be made according to the displayed time interval.

Silence button invokes 'Silence Mode'. This will silence the audible tone (display will continue to

cally after 30 seconds, or when the patient's condition returns to within the preset alarm param-
eters. In Silence Mode, the silence indicator light will glow.

old will be set. The HIGH ("HI") or LOW ("LO") indicator will show in the CYCLE display, and the
