stuff snipped

Those wireless doorbells are a pain in the ass. I've dealt with several
of them. A place I worked has them because the brick building was too
hard to run the wires, but as their maintenance guy, I think I had to
tinker with at least one of them at least twice a month. There were 3
units, since the building was too large for one receiver and separate
buttons. this was in the late 1990s

I've had them, and they mostly suck, I agree. The worst was a RatShack unit
that kept falsing.

About 6 years later I bought one for my home, which has aluminum siding.
Due to the metal siding, it would not work at all.

It's clear these are flea-powered transmitters.

They are unreliable and a pain in the ass. If at all possible, put in a
wired doorbell.

Not possible here. Finished and rented out basement.

Till then, check the batteries with an actual battery tester. Clean
contacts, and pray...... Also, if it's real cold outdoors, most
electronics tend to run poorly, batteries drop in voltage, etc.

Actually, in DC, in midwinter, it's 63F and was about that high for most of
the night. Maybe global warming's for real. (-: I've been here for
almost 40 years and have NEVER seen such a warm winter. Not that I am
knocking it - it's nice not to have enormous heating bills.

I'll be adjusting the unit's operating frequency next. I didn't get a good
look at the manual since I was on my way to get a new car battery. I've
have more time this weekend.
