MEASUREMENTS AND TROUBLESHOOTING
Once all units have been installed and connected the system is ready to receive power supply.
The power supply line to the units must be 12V, as is the case for the BUS line.
If there is a buzz in the sound when the display of the unit is switched on, it is because the digital and analogue
grounds are connected: separate them and the noise disappears.
Clicks can appear in the sound when a shutter or light is switched on. To resolve this situation a filter in the
respective circuits should be used. Usually, an X2 capacitor 100nF mounted next to the load causing the noise
(e.g. lamp or shutter) should filter out the switching noise.
