Probe Failure Alarm:
The alternating two tone alarm is active only in the servo mode.
Activates when the skin temperature probe:
1. Fails electrically due to an open or short circuit, or
2. Is disconnected from the Warmer.
3. Probe senses temperature outside the 30 - 42°C range.
When this alarm condition exists:
1. The heater is turned off and
2. The patient temperature display flashes “HH.H” or “LL.L”.
Patient Temp. Alarm:
This single tone alarm activates in the servo mode when the difference between the
patient temperature and the control temperature is greater than 1°C (can be adjusted to
0.5°C by qualified service person).
Alarm cancels when the patient temperature returns to within 0.8°C of the control
temperature.
