How to interpret “illogical” market testing results

From time to time I’ve made analogies between marketing and home shop experiences and pointed out the simple wisdom that can be found through working with your hands. So bear with me for a moment here as I wind up to a theory on illogical market testing results.

Cindy and Chris at Northside Service Company were miracle workers in bringing my 25-year-old NuTone intercom system back to life. However, when all was said and done there were some glitches. You are supposed to be able to push a button to initiate a call from a remote unit, the recipient is able to talk hands free, and you as the initiator can continue to talk by pressing a button each time you want to speak.

My system wasn’t working like that. You could initiate a call and hear another person and they could hear you, but after that first time you pressed the button subsequent presses did nothing; the signal didn’t go through. There was another issue, minor but consistent across the system: the “end call” button which returned you to whatever you were doing beforehand (like listening to FM radio) didn’t work.

This one-and-you’re-done setup worked fine for summoning kids to dinner or answering somebody who pressed the doorbell. And standing at a wall intercom and talking back and forth in your own home seemed a little Austin Powers-ish. Nonetheless, I wanted to get to the bottom of this.

Through testing I found ONE remote intercom system, out of 16, that worked as it was supposed to. You could press and release that talk button and continue to communicate, and the “end call” button worked as it was supposed to. So I took it apart. And it turned out it was mis-wired. Two wires going to terminals marked “red” and “red/white” were reversed.

I tried mis-wiring a second remote and it, too, began to work properly. I thought about the master controller and what might be wired incorrectly. No schematics are available after a quarter century, certainly not on the NuTone website. Perhaps I made a mistake when I took out the pull connectors to send it in for repair. But I was pretty careful and the pull-off single wire connectors were grounds, so they should not affect the electrical switches.

My guess is that something deep within the system was mis-wired at installation and the original owner put up with it the entire time they lived in the house. There is no other logical explanation because the problem began with an illogical mistake. It takes only a minute or two to remove a remote from the wall and rewire it, so that’s what I’m going to do with the remaining 14 remotes. I’ll also put a note inside the housing of the main controller for a future owner of the house.

Getting to the marketing analogy, many many years ago I worked on a test mailing that involved a bunch of shredded U.S. currency visible through a window in the outer envelope. The product was a newsletter on reducing your taxes, and the message of the involvement device was that you might as well be tearing up your own money for all the unnecessary taxes you’re paying. This test was a disaster. The numbers indicated that absolutely nobody had opened the package and considered responding.

And that was odd. The involvement device may have been a bit sensationalist and there were probably some quirks to the copy, but it followed a solid platform related to the features and benefits of the publication we were selling. I could accept a terrible result of responses that were 20% of the control’s, but 0%? Something is wrong.

My hunch is that somebody at the mail house (or possibly the post office, but less likely since that would be a hanging crime) took a fancy to my gimmick and simply appropriated the few thousand pieces involved in the test. Illogical and far fetched, but can you give me a better explanation?

Happy April Fool’s Day, by the way, but the above is no joke.

Thank you internet! Thank you Chris and Cindy Peters for fixing my NuTone intercom!

My NuTone IMA-4006 Music Intercom. Not only did they rebuild the control unit, Northside Service Company cleaned it up so it looks like new.

I recently moved into a house that has a NuTone IMA-4006 Music Intercom system installed. You can press a button and be heard in another room (or from the porch if you are ringing the doorbell) and also play music throughout the home. I know that sounds quaint in these days of earbuds and instant messaging, but there is a remote unit in every room so it was pretty hard to ignore.

The most recent owners, who lived here for 15 years, had never tried the NuTone intercom system. I experimented by turning a few knobs and got nothing but hum. But at least there was power. Was it possible the system could be restored to working condition? My local NuTone service center said “we don’t know anybody who works on them anymore.” So it was off to the internet.

A search quickly put me in touch with Northside Service Company, a factory-authorized NuTone Service Center in San Ramon, CA. Their site features dozens of links to videos, manuals and articles to help you make the most of your obsolete equipment. I filled out a web request form and a few minutes later the phone rang. It was owner Chris Peters, calling to discuss my system. It turns out that the remote units rarely fail so if I would send him my control station he would rebuild it at a cost that was not cheap, but far less than buying a comparable system today or taking out all those speakers and patching the holes walls.

I disconnected the many wires following Chris and Cindy Peters’ very clear step by step video, then packed it up according to another video of instructions. A couple of weeks later, I got the unit back along with a bag of parts that had been replaced. Not only did they rebuild the unit, they replaced the doors that cover the controls and often break off (the hinges are no longer available so Northside had them custom manufactured) and at my request added an A/V jack and sent me a couple of new lighted doorbell buttons.

It took me a few days to get up the courage to re-install the unit and test it, but I did and everything works as advertised. I’m back in business, feeling very much like a wired denizen of the early digital era.

This is a story that could not have happened without the internet—which helped me find Northside Service Company, and enabled Chris and Cindy to build a site that was incredibly useful and also showed me they knew what they were doing. But the capper was the personal service. I mentioned that Chris called me immediately when I submitted a request. (It was on New Year’s Eve as I recall.) When I had a question about an extra wire during re-installation he answered me by email within an hour. This is a business model many other specialized service providers (copywriters come to mind) can learn from, and emulate.
