DCM1 & DCM1e Installation and User Guide v1.0 50
Display adjustments
The first menu function allows adjustment of the display
contrast and backlight to suit different ambient lighting
conditions. The i and h buttons adjust the backlight level and
the
+ and – buttons adjust the contrast.
Inactivity Time
This function sets the display time-out. Use the + and – buttons
to set a value of between zero and 30 s the default is 10 s.
The display backlight will turn off after this delay, following the
last CDR-1 button press. If the delay is set to zero, or jumper
J1 is left in the Installer Mode position, the backlight remains
on at all times.
Assign Zone
This assigns the CDR-1 to a particular Zone. The + and –
buttons scroll through the eight Zones; note in this function
they are displayed as Zone n even if they have been
renamed. The default setting is Zone 1.
Once a CDR-1 has been assigned to a Zone with the Assign
Zone function, all operations on that CDR-1 will affect all the
speakers being driven from that Zone Output.
It is possible for more than one CDR-1 to be assigned to the
same Zone in a system. This will be useful in some situations,
such as in large rooms. All CDR-1s assigned to the same Zone
will be able to control operation in that Zone.
Set Key
This lets the installer set the 4-character key code used
to access CDR-1 Engineer Mode, once the CDR-1(s) in
a particular Zone have been enabled in the DCM1 System
Menu (with the CDR Zone Setup function).
The bottom row of the LCD first displays the current key;
the factory default is
<<>>. Any permutation of the four
characters <, >, + and – may be used (except four identical
characters); as soon as any of the four buttons is pressed, the
existing key is erased. The key must have 4 characters.
If a key consisting of four identical characters is entered, the
bottom line of the display will show None. This overrides the
requirement for a key to be entered to use Engineer Mode,
and the EQ adjustment and Group Selects screens will be
available to the User as soon as the Zone is enabled in CDR
Zone Enable.
Combining Engineer and Installer Modes
It may be convenient to enable CDR-1 Engineer Mode as each
CDR-1 is being installed, as this will allow the Zone EQ to
be set at the same time. When Engineer Mode is enabled,
the three EQ adjustment functions are presented in sequence
after the User functions, as shown in the flowchart on the
previous page.
