Overview MPX
The front panel of the MPX contains various selectors and indicators. All selection
buttons are implemented using capacitive touch principle, whereby selection is done
by gliding your finger over it.
A zone selection button with indicator LED on top of it is provided for every zone
(4 zones for MPX48 & 8 zones for MPX88). The indicator LED will illuminate when
the corresponding zone is selected. Using the ‘ALL’ (Select all) and ‘CLR’ (Clear all)
buttons, zones can be quickly selected & de-selected for increased user convenience.
The ‘PTT’ (Push-To-Talk) button should be pressed and held when making
announcements. When releasing, announcements will be stopped. An integrated
chime tone will be heard before any announcement is made.
A ‘BUSY’ and ‘ERROR’ monitoring LED indicate the current operation status of the
device. The ‘BUSY’ LED will illuminate while the databus is occupied through another
paging microphone or when the integrated chime is playing. When the ‘PTT’ button is
pressed and the ‘BUSY’ LED is off, accouncements can be made.
The ‘ERROR’ LED will illuminate when no connection is established between the
microphone and the matrix, or when no acknowledge to announcements is given by
the matrix.
