User Manual

Once the connections have been made, the loud-
speakers can be switched on.
ISS™ -function
Both loudspeaker models have a power switch on the
back panel. Set this switch to the “OFF” position when
the loudspeakers are left unused for several days or
when connecting or disconnecting any cables in the
system.
When the power switch is set to “ON”, the ISS™
Intelligent Signal Sensing function powers the loud-
speakers up when playback begins. The mode in-
dicator light on the loudspeaker lights up and the
playback resumes after a slight delay (<2 seconds).
ISS powers down the loudspeakers after the play-
back has ended and the loudspeakers go to standby
mode. The power consumption in the standby mode
is less than 0.5 watts.
Setting the playback level
The playback level of the M030 and M040 can be
matched to the output of the signal source by using
the “Level” toggle switch on the back panel. Three
settings are available. Select the one that gives the
desired playback level and good resolution of the vol-
ume control.
