tube to the thinner metal spout
5. Calibrate the SPL60 probe by clicking the calibrate icon and selecting "SPL Probe"
6. Connect the RECD adaptor to the 2cc coupler and attach to the coupler microphone
7. Click on the RECD test and click start to measure the coupler portion of the RECD measurement
8. Once the coupler measurement is done, the software will prompt to measure the ear portion of the RECD.
Remove the probe tip from the coupler.
9. Proceed with otoscopy, ensuring the ear canal is clear. Select an appropriately-sized probe tip and place it
in the patient's ear
10. Continue with the ear portion of the RECD. The two measurements will be on the screen and the difference
will be calculated automatically

If always using the SPL probe rather than ear moulds, it is possible to create a protocol to ensure that the "Use
the insitu SPL probe" option is always ticked off. For information on how to create protocols, please refer to the
