Testing
Testing the right channel :

lightening together with the yellow LED 'WAIT'.
 When the connection is interrupted again (figure 4.0), the red LED should extinguish and after approx. +/-
6 sec. the yellow LED as well.
Repeat this testing procedure by connecting the point PA to the point +V.

The module is now ready for being connected definitively to the amplifier.
