Heat dissipation mode	Natural heat dissipation
	NOTE:
	The router uses natural heat dissipation. Compared with the air-cooled model, the router surface temperature is high when the device is working properly. This is a normal phenomenon and meets the safety requirements. The router functions and reliability are not affected.
Airflow	Natural heat dissipation
Noise at normal temperature (acoustic power) [dB(A)]	0 (Natural heat dissipation)

	NOTE:
	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.).
