You should be able to get both running even if Conventional is your only option.
Lets address #2 first... I know you replaced the batteries on this one with a BCR however .. how long do the sounds continue on after track power is turned completely off. Should be approx. 6 or 7 seconds.
THe SW Try turning the vol pot up and down a few times. . Yes a dcs remote might help however keep trying with the conventional reset b/w combination.
