occurs, try either a good-quality earthed power distribution block, or the rear panel ground terminal and
connect to an available earth point.

8 Power on/o
With all cable connections successfully made and the volume on connected preamps set to zero, switch
the rear-panel power button to ‘on’ and depress the front panel button to switch the unit from standby
mode to ‘on’. The front panel LED will turn from green (standby) to cyan (on), once the BerTTi has
performed its safety check. BerTTi is ready for use and the preamp volume can now be carefully
increased for playback.
The BerTTi consumes very little energy in standby mode and if desired, can be left switched ‘on’ at all
times.
