I have a Lanier Voicewriter 1000, I cannot locate a manual to give me the instructions on how to listen to previously transcribed dictation from an outside telelphone, I need to dial into the recorder and listen to older transcription, do you have such answers?

It is under the flap located directly under the keyboard buttons. It is a slide switch and you can adjust it for a little recall or a lot of recall.

I don't think that's possible, the minicassette won't fit between the spool spindles. You may be able to use a minicassette player, and route its output to the full-sized cassette recorder, though, or to a little transmitter that broadcasts to a matching receiver in the full-sized cassette player.

go into settings and format the card on the unit.

There is a sensor that detects tape movement. Unfortunately they do go bad and will probably need to be replaced.

We use this equipment in remote locations and have found that the type of phone needs to be a centrex line, such as is used on a fax machine. Note: in the past, we used to have to use an "analog" phone line, which is just a normal phone line.

You probably have two different phone lines involved here.
