Standby/Operation Mode
When the ICS AirCal is turned on the default is airflow on. Pressing the airflow
button will switch the ICS AirCal
between standby mode and operation mode. In standby mode (airflow off), the irrigator is on but the airflow, water and air
pump, fan, warming and cooling mechanisms are off. Standby mode is recommended when the ICS AirCal is connected to
an ICS VNG/ENG and the foot switch is used for starting other tests (e.g., Dix Hallpike) in the Chartr software. Turn off the
airflow when the device is not in use.

Temporary Adjustment
To adjust the temperature for a single patient use, press the
buttons. The - decreases the temperature, the
+ increases the temperature. Press button quickly if small increments are needed or press and hold to change more rap-
idly. The range for the cool temperature is 12°C to 37°C. The range for the warm temperature is 37°C to 50°C. The tem-
peratures are adjustable in 1/10 of a degree increments. To change the warm or cool temperature stored default value,

3.3.3
Switching between cool and warm temperature
The warm
or cool
temperature buttons allow the operator to select the stimulus desired. If the ICS AirCal
is connected to an ICS VNG/ENG system, selecting the caloric protocol (e.g., Left Warm) will automatically select the tem-
perature on the irrigator. Therefore, no manual selection is needed. However, the default startup temperature of the
ICS AirCal should match the temperature of the first caloric protocol in your list (e.g. if you start with Left Cool - default the
ICS AirCal to start with Cool). The startup temperature (cool or warm) can be stored. The default is cool.. See Section
Changing the Stored Default Values
Temperature selection will be indicated on the display panel. If the ICS AirCal is in operation mode only the temperature
currently selected will display. The digital display shows the actual and set temperatures. Once a temperature has been
selected, the display will flash until it r/- 0.4 degrees from the set or default temperature. Time to reach the tem-
perature is < 60 seconds. If the ICS AirCal is in standby mode both the warm and cool set temperatures will display, the
actual temperature will not display.
