ECU. To maintain protection, if this wire is to be shortened at all, it must be cut off at
the end furthest from the fuse.
The ring terminal on the end of the short black wire needs to be firmly attached to
the vehicles metalwork using the self-tapping screw and serrated washer supplied.
A good contact is essential here.
If an external enable is to be used it can be connected now. A switch connecting this
input to chassis when the door is open or a connection to the sidelight circuit are
typical examples of external enables. Any small-gauge wire will be suitable for this
connection.

Step 5: Powering-up and testing
Once the fuse and 12V plug are inserted the remote display should light up showing
a version number. After a few seconds the display should clear down to just a
standby dot showing that the controller is ready. Press the power button on the
remote handset to switch on the zones. If the external enable was active during
power-up it will automatically switch to program 0 instead of entering standby mode.
Adjusting the audio level
The ECU will automatically adapt to different sound levels over a wide range so no
adjustment should be necessary. However a variable attenuator is provided at the
rear of the unit if the sound levels are unusually high. This might be required if the
patterns do not respond well to the music.

The attenuator is adjusted with a
