4.8 Mounting the Volume Control Security Cover
It is possible to install a solid protection over the volume controls to prevent intentional or unintentional changes of the amplifier volume settings.
WARNING: Disconnect the amplifier from the mains before installing the cover.
In the original state the holes needed to fix the security cover on both sides of the volume knobs are hidden behind the plastic front label. In case you wish to install the cover please first pierce two holes in the front label to facilitate the screwing, as shown in the drawings.
To find the exact positions of the holes take the included cardboard template you will find attached on the last page of this manual and place it on top of the volume knobs. The positions of the hidden screw holes are indicated on the template.Then firmly pierce and turn with a pointed tool (we recommend a Philips PH1 recessed head screwdriver) through the cardboard and the label at these positions to obtain a clean hole.You now should see the metal of the fine pitch thread behind the label.
Then remove the cardboard template and fix the cover with the two included M3 recessed threaded screws.
WARNING: Do not use any pointed tools (e.g. screwdriver) with a diameter of less than 3,5 mm (0,138 in),as they might be stucked too deeply inside the screw holes and damage internal components.
