Configuration for extreme thermal conditions

The IX40 has been verified to operate in the temperate range of -40C to +70C/-4F to +158F.

However, in extreme temperature conditions (up to +70C/+158F), you must add a Quality of Service (QOS) rule that limits the upload speed of the modem to 1 Mpbs. For less extreme temperatures, a modem upload speed of up to 10 Mpbs is acceptable.
