CCR3 Controller
The SD card may never be installed or removed from
the CCR3 Controller when data is being written to it,
this may lead to:
– data loss
– SD card damage
– CCR3 Controller damage.
INSTALLING THE SD CARD
Disconnect the controller from the power supply for
at least five seconds before inserting the SD card.
The SD card may only be installed after this pause.

From ACCESS CODE menu quadruple press up arrow
key "▲" without entering any code it will give access
to "SD Card Exchange". SD card can be pulled out
safely from CCR3 Controller (process of date recording
is interrupted).
Power failures occur as data written to the SD card may
also corrupt the archive or even damage files stored
on the card. To reduce this risk, it is recommended
to use a buffered power supply for a CCR3 Controller
used with the data archiving function and to set the
"Archive" setting to "2 Files." The archive files will be
doubled, but the storage space will drop by half.
