So just to be clear, that would be this info:
The issue may be occurring if someone has an older model node and is using one of the following LNBFs that have the following serial number prefix markings identified by the 1st 6 characters of the serial number. (see attachement)
D1000.4 WA Triple LNBF, A122A7
D1000.4 WA Triple LNBF, A72201
D1000.2 Triple LNBF, A11201,A11202,A11203
D1000.2 Triple LNBF, A71201,A71202,A71203
D1000.4 EA Triple LNBF, A71C01
If you have an older model Duo Node and are experiencing these issues, then the LNBF needs to be replaced. An updated Duo Node design is already in inventory to enable all LNBF versions to be used in cold weather conditions. Updated Duo Nodes may be identified by black dots on the carton and unit labels.
