I have been having problems with the 880- charger. The last 2 I put in, you had to insert the cable just right and push it a certain way to get it to charge. Check your rf light on the 350 and see if it is glowing red. your new remote may do exactly the same thing. had a customer install a new dvr and it kill the antenna. move your antenna around until the rf light goes out.

any one else had charging issues?
