The sound volume of the NOCH Sound Scenes is pre-programmed and therefore not adjustable.
You can lower the sound if you install the sound module under your layout. If the sound volume is still too loud for you, you can lower it using the suitable 10 Ohm resistor.
It is very easy to install the resistor without prior knowledge.
1. The simplest method is to cut the red cable (that leads to the loudspeaker) with a cutter and to solder the resistor in it.
2. If you don’t have a soldering iron at hand, you can use a luster terminal to make the connection.
