1) Open the REM440 module.
2) Select a test protocol that includes Visible Speech Mapping and RECD in the List of Protocols.
3) Explain the procedure to the client/relatives.
4) Perform otoscopic examination.
5) Perform the RECD with the client's own ear mould or the SPL probe (see section 0). Also note the
option to select a predicted RECD (see section 0).
6) Place the hearing aid in the test box as shown below and ensure that it is switched on.
It is important that the reference microphone is placed in the same acoustical point as the
microphone in the hearing aid. The placement may therefore differ a little depending on the hearing
aid you are testing.
