Test

Use of the test fixture is mandatory for all Pixel BTE during AUDIOmaster testing. To use the fixture, place the instrument under test in the fixture according to picture. Connect the pro-gramming cable and select PL70 test program in AUDIOmas-ter. During the test program execution the IAD calibration will be performed at the appropriate time. Another bennefit from the fixture is that the instrument is in a well defined position so the telecoil test can be performed without any interaction from the operator.
