Turning Temperature Alarm Audio Off
WARNING
• Never disable an auditory alarm if this action could compromise patient safety.
• Do not rely exclusively on the auditory alarm system for patient monitoring. The most reliable
method of patient monitoring requires correct operation of the monitor and close observation of
the patient.
Alarm audio is on by default unless either of the following is true:
• You are operating in Alarms Off monitoring mode (if this mode was enabled by your
system administrator). See “Alarms Off Mode” on page 4-16.
• Audio is globally turned off (if this option was enabled by your system administrator).
See “Global Audio Off Mode” on page 4-15.
In the Temperature menu, you can touch the Alarm Audio On/Off button to toggle
alarm audio on and off. For details, see “To turn off alarm audio for one measurement”
on page 4-9.
Changing the Temperature Alarm Limits
For information on changing the temperature alarm limits, see “Changing Alarm Limits”
on page 4-7.

Verifying the Temperature Accuracy
The temporal thermometer reads the infrared heat waves released by the temporal
artery, which runs across the forehead just below the skin. Arterial temperature is the
same temperature as the blood flowing from the heart via the pulmonary artery. It is the
best determinant of body temperature and unaffected by the artifactual errors and time
delays present with oral and rectal methods.
To ensure accurate readings, consider the following guidelines:
• Temperatures measured with the temporal thermometer is normally never
appreciably lower than oral temperature. Low temporal temperature readings are
usually due to any of the following:
- Dirty probe lens
- Scanning too fast
- Scanning down the side of the face
