Sub-Zero Start Up
If the MFR 4K camera is powered on at temperatures below -15°C the primary and secondary
heaters will both be enabled.
The camera will remain powered down until the internal temperature rises above -15°C
Once the internal temperature rises above -15°C the camera will start up, the primary heater will
turn off, keeping only the secondary heater turned on.
The secondary heater will remain on until the internal temperature rises above -5°C.
During use the secondary heater will toggle on/off between -5°C and -15°C to continually regulate
the internal temperature.
Powering on in sub-zero temperatures
The MFR 4K camera has an internal heating system so if it is switched on in sub-zero temperatures
it will start up in a controlled method so as to ensure reliable operation.
