Section 3: Conguration

The DCM1 can be congured in a variety of ways to suit all

installed situations. Most conguration functions are accessed

through the menu system.

For convenience, the DCM1’s basic block diagram is repeated

here:

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 conguration 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 ve submenus:

• Music

• Routing

• System

• Priorities

• Groups

Each submenu is entered by pressing its dedicated button;

selection is conrmed 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
