4.2.1 Static Test (Estimated Battery Life)
The Static test estimates the battery life of the hearing aid. To turn on the test:
1. Enter the Battery screen (as described above).
2. Use [F7] to set the battery size: Press [F7]. Use [, ] to select the battery
size of the hearing aid. Use [] to complete the selection and close the popup
menu.
3. Use [F4] to toggle the Static Tone to On. The estimated battery life should
now be displayed below the ma/Freq graph. See Figure 4.2.
By default, this test uses a pure-tone stimulus of 1000 Hz at 60 dB SPL. The
current source selections are shown in a box below the mA/Ampl graph on the
right side of the screen. You can:
• Change the source Type by using [F3]. Toggle between Puretone and
Composite,
• Change the source Amplitude by using [, ], and
• Change the source Frequency by using [, ]. This setting is only available
when the soucre type is set to Puretone with [F3].
