Aux port to alignment tone headset wiring
A standard 32 ohms stereo headset can be connected to the AUX port to use the audio alignment
tool. The diagram of the adapter is provided in
Figure 21
. The recommended values for both
resistors are 220 ohm, 0.25W. Different resistor values can be used to optimize the level of the
audio signal depending on the headset characteristics and the level of ambient noise.
