member of a Group. If so, the next press of ZONE after the
panel “wakes-up” displays the Engineer Mode Enter Key

The + and – keys may now be used to change enable or
disable any Groups of which the Zone has been dened as
a member. If the Zone is only a member of one Group, the
lower row of the display will toggle between Zone n and
Group m where n and m are the Zone and Group numbers
respectively. If the Zone belongs to more than one Group,
the additional Groups will be displayed in turn; pressing
ZONE when a Group is displayed will enable that Group;
pressing ZONE when the Zone is displayed will disable a
Group and return to normal operation.
Engineer Mode
The CDR-1s may be placed in Engineer Mode to allow EQ
adjustment to be performed from within the zone itself.
Engineer Mode is fully described at page 35.
Installer Mode
Installation of a CDR-1 necessitates the activation of a
further mode, Installer Mode, to allow some additional
parameters to be set, including zone assignment.
To activate Installer Mode:
If the CDR-1 has already been installed, remove it from its
back box and disconnect the power supply, either by
unplugging the POWER IN RJ45 connector if the CDR-1 is
being powered from elsewhere in the system, or by
unplugging the local PSU if it is being powered locally. Move
the jumper J1 as shown below.

Normal Mode Installer Mode
Reconnect the CDR-1 to its power supply, and the
display will change to the rst of the four menu functions
available in Installer Mode. Pressing ZONE steps through
each function in turn (in the same manner as the NEXT
FUNCTION button in the DCM-1’s menu system). The two
User Mode screens are also presented before the menu
loops around.
The i , h , + and – buttons are used to adjust the parameters
in each function.
Note that the display time-out is disabled in Installer Mode.
Remember to unpower the CDR-1 and put J1 back to its
“normal” setting after conguration is complete.
