Temperature |
Operating temperature: 0°C to 45°C (32°F to 113°F) at an altitude range of 0 m to 1,800 m (0 ft. to 5,905.51 ft.) Note: At an altitude between 1,800 m (5,905.51 ft.) and 5,000 m (16,404.20 ft.), every time the altitude increases by 220 m (721.78 ft.), the maximum temperature decreases by 1°C (1.8°F). Storage temperature: –40°C to +70°C (–40°F to +158°F) |
Operating temperature: -40°C to +65°C (-40°F to +149°F) at an altitude range of 0 m to 1,800 m (0 ft. to 5,905.51 ft.) Note: At an altitude between 1,800 m (5,905.51 ft.) and 5,000 m (16,404.20 ft.), every time the altitude increases by 220 m (721.78 ft.), the maximum temperature decreases by 1°C (1.8°F).
