Selecting a DAK, while turning the controller clockwise or counter-clockwise, causes the cross-point
level to increase or decrease, respectively. The cross-point level indicator and a numeric indication of
the level setting is displayed while the DAK is pressed.
Only one DAK press is recognised at a time for cross-point level control. Further DAK presses are
ignored until the first DAK is released.
After 20 seconds without any DAK or pot activity the panel automatically exits Level Control Mode and
reverts to normal intercom mode.
4.8.3 Shift Pushbutton
The Shift pushbutton toggles between the Main Page and the additional DAK assignments of the Shift
Page. The red LED will flash when a call is detected for an assignment on the page not currently
displayed. When that page is accessed, the LED will illuminate.
NOTE: SOFT Mode can be entered when the Shift Page is selected, allowing local assignment of the
Shift Page DAKs. However, the Shift Page MUST be selected before SOFT Mode is entered as the Shift
pushbutton is only functional in normal intercom mode.
4.8.4 Microphone Mute Pushbutton
Press the Microphone Mute Pushbutton to mute the active microphone. The red LED is illuminated whilst
the microphone is muted. Another press will re-enable the microphone.
4.8.5 Loudspeaker
Audio is output from the loudspeaker unless the Headset Select is engaged.
4.8.6 Headset Select Pushbutton
The Headset Select Pushbutton is used to select headset operation. The red LED is illuminated to
indicate that the headset microphone is active and the detachable microphone and loudspeaker are
muted.

Your panel loudspeaker reduces volume automatically when a talk key
is pressed. This is to help reduce the chance of howlround (audio
feedback) occurring.
