Display adjustments
The rst 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 seconds; the
default is 10 seconds. The display backlight will turn off after
this delay, following the last CDR-1 button press. If the delay
is set to zero, the backlight remains on at all times.
Assign Zone
This assigns the CDR-1 to a particular Zone. The
+ and – buttons scroll through the 8 Zones; note in this
function they 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 DCM-1 System
Menu (with the CDR ZONE SETUP function).
The bottom row of the LCD rst 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 Select screens will
be available to ther 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 owchart
on page 47.
