1. Launch the Affinity
and click on the REM440 tab
2. From the Protocols and Sessions drop down list, choose a protocol that includes the RECD (ex: Pediatric
Aided Response)
3. Connect the thicker RECD probe tube to the larger metal spout on the REM headset and connect the
regular probe tube to the smaller metal spout
4. Calibrate the probe tube by clicking the calibrate icon and selecting "Regular Probe"
5. Connect a tube nipple to the other end of the RECD probe tube
6. Connect the tube nipple to the BTE tubing attached to the 2cc BTE Adaptor
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.
Disconnect the tube nipple from the RECD probe tube and connected to the ear mould tubing
9. Proceed with otoscopy, ensuring the ear canal is clear. Place the probe tube inside the patient's ear and
position the ear mould, connected to the RECD probe via tube nipple, in the ear canal
10. Continue with the ear portion of the RECD. The two measurements will be on the screen and the difference
will be calculated automatically
11. The RECD can now be used for the hearing aid fitting. The RECD can be imported, if that feature is
supported, manually into the hearing aid software. The fitting will be recalculated while taking the RECD
1
into account . To view the RECD values, click on Table View
12. To proceed with the hearing aid verification, click on the REAR button; the software will automatically go
into the coupler mode and it will then be possible to proceed with the verification. The default fitting
formula will be DSL v5 Pediatrics. Use the hearing aid software to fine tune the hearing aid and to ensure
that the output is matching the DSL targets for soft, average, and loud, using a speech stimuli (like the
ISTS). Measure the MPO to ensure that the output for loud sounds is not hitting the UCL.
