- Adapter (1) is designed for use with ITE, ITC and CIC hearing aids.
Make certain that hearing aid is securely connected by using adhesive
insulating putty.
- Adapter (2) allows connection of BTE type hearing aids to coupler
using an ear hook.
- Adapter (3) is designed for use with RIC hearing aids. Here again,
always use adhesive insulating putty to make certain of a secure
connection.
Once the hearing aid has been suitably connected to the coupler, the test can
be conducted by positioning the device on the RECD unit (aligned centrally
with the loudspeaker if possible) and ensuring that the reference
microphone is placed as close as possible to the hearing aid microphone, but
without actually touching it. Remember also that it is not advisable to use
RECD in the case of open fit hearing aids.
An example of correct positioning is shown in the following illustration.
