Notes:

1. The upper temperature limit must be lowered 1º C for every 137 meters of elevation above 915 meters.

2. The upper wet bulb temperature must be lowered 1º C for every 274 meters of elevation above 305 meters.

3. The GTS 250 contains a temperature sensor which reads the temperature inside the router. Do not confuse readings you see there with the ambient temperature values. The temperature inside the enclosure will be higher. This is normal.
