Overview
●
Rotary/push knobs.
● Labelled unit buttons (hard keys).
● Function buttons (soft keys).
Rotary/push knobs
The left-hand rotary/push knob ⇒ fig. 1 1
is referred to as the volume con-
trol  or the on/off switch.
The right-hand rotary/push knob ⇒ fig. 1 8
is referred to as the setting
knob.
Unit buttons and function buttons
The system labelled buttons are called “unit buttons”, e.g. SOUND
button
⇒ fig. 1.
There are six unlabelled unit buttons below the screen ⇒ fig. 1 7
. These
are known as “function buttons” because their function depends on the ac-
tive function mode.
The current function of a function button is displayed just above the button
in the bottom line of the screen (e.g. ⇒ fig. 6). 
Switching on and off
● To switch the unit on or off manually, briefly press the rotary/push knob
 ⇒  fig. 1.
When the unit is switched on the system starts up. The last audio source
used is played at the last selected volume setting, provided this does not
exceed the preselected “switch-on volume” (ON-VOL or START-VOL
⇒ page 40). 

voltage falls below the minimum onboard power supply voltage, a signal
sounds and LOW BATTERY appears. You should switch the unit off.
