An ignition switched accessory terminal can be veri-
fied by measuring the terminal while operating the
vehicle's key switch. With the ignition key in the
"accessory-ON" position, the terminal voltage
should measure the vehicle's battery voltage. With
the switch in the "OFF" position, it should measure
near zero.
The Car Kit supports an "Entertainment Mute" func-
tion when connected to an audio system that pro-
vides for external muting. This function is
compatible with systems that mute the audio output
when the control line is connected to ground.
