The menu system has two modes: User Mode and Installer
Mode.
User Mode:
User Mode is the default menu system mode which is available
at all times. It provides the user with the system control
functions needed on an everyday basis: music source selection
and level control for each zone, and group activation.
Installer Mode:
Access to Installer Mode is key-protected. The user should
ensure that only authorised staff who have been trained in the
DCM1’s configuration functions know the key. Installer Mode
allows adjustment of zone EQ, maximum and minimum levels,
microphone assignments, paging and priority parameters,
group membership and all other system setup parameters.
Installer Mode is selected by pressing the
INSTALL
button,
and entering the key code via the numeric buttons below
the display in response to the prompt
Enter Key
. The
key is always a 4-digit number; only digits 1 to 8 are allowed.
The factory default key can be found in the Appendix; users
are strongly urged to change the key as soon as the system is
commissioned. A time-out applies to Installer Mode; if no keys
are pressed within 45 seconds, Installer Mode will cancel and
the unit returns to User Mode.
Navigating the menu system
The menu structure is divided into five submenus:
•
Music
•
Routing
•
System
•
Priorities
•
Groups
Each submenu is entered by pressing its dedicated button;
selection is confirmed by its adjacent LED.
The Routing, System and Priorities submenus are only
available in Installer Mode, as are most of the functions in the
Music and Groups submenus.
Navigation within all the submenus is performed with the
NEXT FUNCTION
button, the rotary control and the
eight numeric buttons. In general,
NEXT FUNCTION
button steps through the selected submenu one function at a
