I have a KX-TCM418ALW phone answering machine combo thingy
and as it works perfectrly well I don’t want to get rid of it.
However, I have lost the manual and can’t remember how to adjust the time stamp or how to set the number of rings before the machine kicks in.
Go to the Panasonic website and search for the model thingy you own. User manuals – even for old or discontinued devices – are usually available on the site for download or reading. I have yet to not find an old manual for some electronic appliance (though admittedly I’ve never tried it with a Panasonic device).
Seems to be an older model which is why it’s not on Panasonic’s website. It’s a 49 MHz phone, and they haven’t made these in a number of years. Can you post a link to a closeup photo of the buttons on the base unit? I might be able to tell you a few things to try. I’m usually pretty good at working things without the manual. I’ve never met a digital clock or watch I couldn’tset.
