There is a delay between a physiological event at the measurement site and the corresponding alarm at
the monitor. This delay has two components:
The general system delay time is the time between the occurrence of the physiological event and
when this event is represented by the displayed numerical values. This delay depends on the
algorithmic processing and the averaging time.
The time between the displayed numerical values crossing an alarm limit and the alarm indication
on the monitor. This delay is the combination of the configured alarm delay time plus the general
system alarm signal delay time.

Adjusting the Pulse Alarm Limits
See "Adjusting the Heart Rate / Pulse Alarm Limits" on page 221.
Setting Up Tone Modulation
If tone modulation is on, the QRS tone pitch lowers when the SpO
tone is derived from either heart rate (from MECG) or pulse (from built-in SpO
