Recently got a used Panasonic kx-tg2740 phone and we are having trouble programming it. Is there manual for the main unit and handset set=up?

Have you forgotten how to use Google?? :mad:

Just search for:
"Panasonic kx-tg2740" manual
(including the quotes) and you'll get thousands of results, the first few of which should turn up a downloadable manual. Here's one download source:
