external FFC mode, the “FFC desired” flag is intended to indicate to the host to command an FFC at the next
possible opportunity.
Lepton automatically prohibits the shutter from operating when it detects the temperature to be outside the
range -10°C to +80°C

. For example, if the camera is operating at a temperature of -15°C, no automatic FFC will be
performed, and the camera
will ignore any commanded FFC if the FFC mode is “automatic” or “manual.” Normal
operation of the shutter will automatically resume when the temperature is back within the valid range. A status
flag is provided in the telemetry line indicating when shutter lockout is in effect.

Lepton 2.0 and 3.0 have an upper shutter lockout temperature set to 65 °C.
