4.1.1
Speculum
Warning
•
Never place the inner speculum directly into the patient's ear.
An outer disposable speculum should always be placed on the delivery head prior to performing an irrigation on a patient.
The outer disposable speculum is intended to be single-use only.
4.1.2
Lens
The Lens can be cleaned with a cleaning cloth like the Otometrics optical cleaning cloth (part # 7590527). If the lens is mis-
handled and broken a new lens can be purchased. Slide the broken lens out and slide the new lens into place. See Section
for an Accessories list.
4.1.3
Light on/off button
The light should be left on during irrigation in order to view the tympanic membrane (i.e., the eardrum) to ensure that the
airflow is being directed properly.The light defaults to on when the ICS AirCal is in operation mode. The light will flash
when the caloric test/irrigator is initiated by pressing the foot switch or the activation trigger on the delivery head to con-
firm initiation of the devices. If the ICS AirCal has not been used for 10 minutes the light will automatically shut off.
4.1.4
Activation Trigger Operation
If airflow is on and temperature is +/- 0.4 of the set value, pressing the activation trigger on the handle will start the count-
down timer and flash the light in the delivery head (set temperature must be reached in order to start timer and for light
to flash).
If the ICS AirCal is connected to an ICS VNG/ENG system:
In VNG, first depression also starts the tracing and successive depressions start the video recorder or center tracing depend-
ing on software configuration.
In ENG, first depression also starts the tracing and successive depressions centers the tracing.
If the computer is turned on but the Otometrics VNG/ENG software is not running, flow time may be activated by holding
down the flow time activation trigger for 5 seconds. The functions of the flow time activation trigger operate in parallel
with the foot switch on the delivery head.
Pressing the activation trigger on the handle more than once will NOT stop or restart the countdown timer.
If airflow is off, pressing the activation trigger on the handle will NOT start the countdown timer.
4.2
Foot Switch
4.2.1
Operation
A foot switch is used to activate the flow timer.
If an ICS VNG/ENG system is connected and a caloric test has been selected in the software, the first depression of the foot
switch will initiate the duration timer and the recording of the trace in the software; subsequent depressions will center
the tracing (ENG/VNG) or start the video recording (VNG only).
If the computer is turned on but the Otometrics VNG/ENG software is not running, flow time may be activated by holding
down the foot switch for 5 seconds. The functions of the foot switch operate in parallel with the flow time activation trig-
ger on the delivery head.
