Does anybody know: Will two units work side by side, or will they interfere with one another?

I believe that each unit has its own ID that it operates on. This allows several to be in the same room and not interfere with each other. I have several wireless mouses in the same room and they have not interfered with each other.

It has the same wireless tech as a 2.4 GHz wireless phone. That said, they should be fine side by side.

I actually did this and it does work. You have to make sure that you get two units that have the same frequency. HOWEVER, you cannot use one switch to control two boxes (my original plan) -- it will alternate them on and off.

Yes I believe so im pretty sure both separate packs will run on the same frequencies and will cause both separate systems to get tangled with one another

I have two of these units in my home and they are I'm adjacent rooms but I've never had a conflict. I'm not sure if they are on the same channel or not.

There should be no problem. I ordered two of them and never had any interference. You can also change the code by opening both the transmitter and the receiver and change the location of the jumpers as long as botth jumpers are in the same location. It is explained on the instructions page. Enjoy your units.

From what I have read if you have two wall controls they might interfere with each other if they are not spaced about 6 - 12 inches apart. Might try to space them apart even if its just a couple of inches to see if that helps.

Nope. They don't interact/interfere with each other. If yours doesn't work, check the battery (it could be dead or installed upside down). If you don't have a multimeter, swap the batteries in the two collars...

I had no trouble with any of mine (I have 3 units). Just make sure they are right side up-first time I tried putting them in up side down.

Susan, the two models will work independently of each other. Each base will need to be connected to your line. Thanks!

it should. I haven't tested it but I don't see what would cause them to not work together.

You would have problems with the connection from one unit to the other. I think it could be hacked, but it would take some imagination and know-how.

Only thing I could see that would possibly interfere with doing that is the wireless sub. I would contact Polk and see if is possible that there may be interference. Other than that I don't see an issue.

They won't sync together where the parent unit hears both children in one unit. But we own two sets. I have one in each child room and then a parent unit for each child on the kitchen counter. They do not interfere with each other at all.

I have two sets in close proximity. They don't interfere with one another. My two remotes only control their respective controller. I did no programming. It's the way they came out of the box. In the directions there are ways to couple and uncouple the remote with the controller but I didn't need to get into that.

Yes, I have 2 and they both work at the same time. I have both a white one and a red one, both model ET-732, and both work together. You just sync each one to its remote separately and they update at different intervals so there's no interference.

They have to be separate. One is to provide power and the other is for metering. Won't work right together.

This is a known issue with 888LM units, when both units are placed next to each other. See the following support article: http://chamberlain.custhelp.com/app/answers/detail/a_id/6159/~/gdo-service-bulletin%3A-8%2F30%2F13%3A-888lm-myq%C2%AE-control-panel---potential-erratic
