D816 Volume Problems
D816 Volume Problems
(OP)
There was a bad CO Line position on this unit about 1 year ago so I moved the Line to CO position 3. This worked great....until now.
The customer is experiencing problems with being heard on an outside call. The customer can hear fine.....just the outside caller has a volume problem. This is on all lines and on all sets. I checked the incoming lines at the demarc and they are working good.
I want to change out the 4 CO Line card. How involved is this, other than the standard static precautions and power down etc? Will I Lose programming when I do this?
