NOTE: At the beginning of this process, the outputs
of the KEYLOC are muted. At the end of this process,
the KEYLOC will begin to pass audio.
Turn the OUTPUT gain adjustment down!
1. Turn down the INPUT GAIN and OUTPUT GAIN
adjustments - fully counterclockwise.
2. Set the Factory Source Unit's volume knob - set it
to the maximum clean volume level that is not clipped
as confirmed in the previous steps. If you didn't test
for clipping, set radio volume to 75%.
3. In the factory source unit's audio menu, confirm
the Bass and Treble and Balance and Fader controls,
and any Equalizer controls, are all set to 0 or their
neutral position. Turn off any settings such as speed-
compensated volume, or any audio processing you
don't intend to use with the upgraded system.
4. Press and Hold the KEY button for 8 seconds. The
LEDs will sweep from 1 to 4, and then illuminate 2,
1+2, 1+2+3, and then 1-4 together.
