Long-term operating temperature [°C(°F)]:-5°C to +50°C (23°F to 122°F) at an altitude of 0-1800 m (0-5905.44 ft.)
Restriction on the operating temperature variation rate [°C(°F)]
When the altitude is 1800–5000 m (5906–16404 ft.), the highest operating temperature reduces by 1°C (1.8°F) every time the altitude increases by 220 m (722 ft.).

Devices cannot start when the temperature is lower than 0°C (32°F).

The operating temperature ranges from –5°C (23°F) to +45°C (113°F) when optical modules with transmission distances greater than or equal to 60 km are used.

The device does not support dying gasp when the ambient temperature is higher than 40°C (104°F).

Storage temperature [°C(°F)]:–40°C to +70°C (–40°F to +158°F)
