Refrig/Freezer Temperatures Adjustment

Gang:
We have the Dometic NDR-1292 double door refrig. The refrigerator side is plenty cold (just at freezing on cold selector position #3). The freezer side is at about 12 degrees F. and we would like it colder, at about the recommended NSF temperature of 0 degrees F. Our ice cream gets too soft for our likes.
Is there any way to adjust the freezer temp seperate from the refrigerator temp. like in home refrigerators? I couldn't find anything in the manual or on a forum search.

Thanks to all of the great Heartland Owners out there for all of the good tips I pick up here and put to use, and you don't get a credit/thanks every time they are used!!!

Bill, This is ugly, You'vd have 24 views and no answers, yet your question seems like it is one we could ALL use an answer to = ya stumped the forum dude... and that ain't good !

This may be a question for the factory?

Bill, its simple. In the morning call Dometic. They built it...so they should be able to help you.
