Unfortunately the closest I’ve found was this one where the unit on the right on the first page looks like the right model, but it doesn’t say your model specifically unfortunately.

Edit: Well just in case some part numbers match, here is that one: https://files.catbox.moe/660s6h.pdf

This is only the user manual, but hopefully it helps:

User manual seems to be pretty readily available online, looks like the 51420 and 51220 have the same user manual. Unfortunately I didnt see the service manual in a quick search.

The only hints I did see (and it wasn’t explicit or I would have screenshot it for you) were around under voltage causing it to blink,the door lock not working correctly, and the drain as you mentioned.

So what may be worth checking is that the electrics all have a good physical connection (and if you have a multimeter, even better to verify stable voltage), checking the fuses, and checking that the door lock is operable.

Is there any noise to speak of, like the door lock clicking?

Its going to depend on a few factors, but lower frequencies (longer wavelengths) have more penetration.

So it will, but how much would depend and you’d probably be best just grabbing one station to set up and test, and a portable to see what kind of coverage you get.

Or just start with a base at the house and a portable and walk around.

Edit: typo

We are upping the cost and complexity a bit, but I want to point out this is where mesh shines by adding some stationary nodes. Solar, battery (depending on how easy it is to get to), etc and add coverage.

This is actually the 2nd one, first one got a warranty replacement after a coworker (who I expected better of) borrowed it.

Thats what started the radio shack only loaner program lol

I’d rather help them by using the fluke myself than risk this one dying through mishandling again.

I still have mine in my bin! I don’t use it much anymore (I got a Fluke for free), but when someone asks to borrow its that one that goes in their hands.

Because I’m not letting people borrow my Fluke.
