Hi,
I have acquired an old Northern Telecom phone, but I have no instructions. The phone has no model number, but has "Rd.1982 Rd.1983 Rd.1985" on the base. Also on the base is stamped in ink "BEL541" (the '5' is a guess). On the top are a programming button (which you access by removing a clear plastic piece) and eight buttons. Below this is the regular touchtone keypad, and three red LEDs; the left LED lights up when you lift the handset. Under the handset is a three way slider with "O" on the left and "III" on the right. It is not cordless.
Amazingly, somebody described this exact phone on this newsgroup in 1999, look:
What I now need to know is: o Which of the eight buttons are Flash and Redial. o What does the O - III slider do. o What do the three red LEDs indicate.
Many thanks for any help you can give.
