Attention
The delivered MCM Print will be damaged if it is installed
for the use of the singleframe equipment in older ARRIFLEX
435/435ES cameras. In order to avoid this, the version
of the CMC print in the ARRIFLEX 435 has to be checked
before the delivered MCM print is installed.
To check the CMC Print version:
• Take the electronic cover, the functional expansion
module (FEM) and the video module off.
The CMC print is now visible in the 435.
• In the top right corner of this print, there is a number
shown like: 1030-23-71-00-01-D
• If the last letter of this number is an A or B the CMC print
of the camera has to be exchanged for a newer print.
Do not install the delivered MCM print!
Ask your local ARRI support for the installation of the
new CMC print in the ARRIFLEX 435.
If the last letter is a C, D or higher you can do the single-
frame conversion as described in this manual.
