The optional insert earphone package is available (PN 015-0418-00). It includes:
- ER3A earphone with 1/4″ plug
- 72″ cable
- Assortment of eartips
- Instruction booklet
- Calibration certificate
- Lapel clip
The Insert Earphone Package will enable you to take an RECD (real-ear to coupler difference) measurement with any FONIX hearing aid analyzer. When used with the FP40 analyzer, FP35 analyzer, or the WinCHAP computer hearing aid program, the coupler measurement can be stored permanently. This means you will only have to take the real-ear measurement to obtain the RECD for each client—cutting the time on RECD in half!
P.S. Need extra eartips? We stock three sizes.
