| Restriction on the operating temperature variation rate |
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.). |
| The device can work for a short period of time when the operating temperature is beyond the normal range, but the following conditions must be met: |
| - The operating temperature can exceed 45°C (113°F) for a maximum of 96 consecutive hours in a year. |
| - The total time when the operating temperature exceeds 45°C (113°F) in a year is less than or equal to 360 hours. |
| - The number of times the operating temperature exceeds 45°C (113°F) is less than or equal to 15 in one year. |
| If any of the preceding conditions is not met, the device may be damaged or an unknown error may occur. |
| Devices cannot start when the temperature is lower than 0°C (32°F). The maximum transmission distance of an optical module used for short-term operation cannot exceed 10 km. |
| Long-term operating temperature |
