Note(s) 
1. Lepton contains an automatic shutdown feature when its internal temperature exceeds the maximum safe operating value. 
See Power States, page 15. 
2. Lepton contains an automatic shutter lockout feature that prevents the shutter from operating when its internal temperature 
is outside the range of -10°C to 80°C for Lepton 2.5 and 3.5, and -10°C to 65°C for Lepton 2.0 and 3.0. See FFC States, 
page 18.
