ARRI ALEXA Series User Manual

Warning and Error Messages Appendix 261
A.4 Warning and Error Messages
If anything unwanted occurs in the camera, it will give a message to the
user.
These states, which require attention from the user, are indicated by
icons in the main display, the viewfinder and the MON OUT.
Warnings inform the user that a state has changed or that an error is
likely to occur, but recording is still possible.
When the camera goes into error state, recording is no longer possible,
as it cannot be guaranteed that images are acquired as the user
intended, or it is not possible for the camera to record.
The messages give a compact description of what has happened. If
more information is required, please refer to the following tables.
Special warnings and errors: Sensor temperature
ALEXA has a Peltier element that keeps the image sensor at a stable
temperature. This is important to achieve constant image quality. In
certain situations, the camera might not be able to keep the optimal
temperature, or it might take some time to reach the optimal
temperature. This may be the case directly after booting, or in very hot
or cold environments.
A red temperature icon indicates that the sensor temperature is too far
off to guarantee a high image quality. A white temperature icon
indicates that the sensor temperature is not optimal, but image quality
is still within the (very high) quality limits required by ARRI.
The related messages in the INFO screen are shown in the following
tables.
