– PC850 Operating Manual

USING THE PC850 (COMPUTER CONTROLLED)
4.1.
GENERAL
Please note:
Before the PC850 can be used as an automatic audiometer, the operating software and the
Audibase application must be installed and registered on the connected PC. Refer to the relevant section of
the Audibase operating manual for details of this operation.
On start-up the display will show the following default setting:
SIGNAL dBHL
FREQUENCY Hz
30dB 1kHz
< > < >
This indicates that the audiometer is now ready to be used for automatic testing which is initiated by Audibase
and controlled by the PC850 software.
4.2.
SWITCHING THE AUDIOMETER ON AND OFF
Press and briefly hold the switch marked
(located on the back panel). No warm-up time is required. The
display will briefly show the model and the type of headphone currently in use. To switch off, press the switch
marked
again, or press and hold the MENU key followed by the YES (RIGHT) key and then release both.
4.3.
USING THE TALKOVER FUNCTION
If the TALKOVER key is pressed while an automatic test is in progress the test will be paused with a dialogue
box displayed as below.
After any necessary instruction is given to the patient and the TALKOVER key is released, the operator can
choose to stop the test (“Abort”), retry the frequency that was being tested when the TALKOVER key was
pressed (“Retry”), or skip the frequency that was being tested and move on to the next frequency (“Ignore”).
4.4.
STARTING THE SOFTWARE
Please note:
Before starting an automatic test it is important to clear any current test readings from the
audiometer (typically these would be retained thresholds from a previous manual test). If this is not done then
dealing with any error conditions could become problematic.
Start the Audibase application, and with reference to the user manual either establish a new a patient, or
access and display details of an existing patient.
