CDR‑1 & CDR‑1F Installation Guide v2.0 15
Each CDR must be assigned to a zone; this will normally be the zone in which it is
physically located. As shipped from the factory, a CDR has no zone assigned, and when
powered for the rst time it will rst display the backlight/contrast adjust screen, and
then prompt for a zone assignment before continuing, as shown below:
Use the + and – keys to scroll to the zone required, unless Zone 1 is correct. Press the
ZONE button to accept the assignment (the display changes to the Set Key screen);
after a few seconds, the CDR will enter normal User Mode, with the zone assignment
conrmed.
If it is necessary to change the zone assignment at a later date for any reason, this can
be done by putting the CDR into Installer Mode (see below).
Installer mode
To put the CDR in Installer Mode:
• Remove the CDR from its back box or mounting position by removing the two M3
screws at the bottom of the housing in the case of the CDR-1, or by removing the
two front xing screws in the case of the CDR-1F. Retain the screws.
• Remove power from the CDR, either by powering the system down or removing
the POWER IN connector.
• Move jumper J1 from OFF to ON
• Reapply the power
