Sharp FO-1660M Operation Manual page 85

Note: All telephone lines accept pulse dialling but only modern types of
exchange systems accept tone. To check your line type lift the receiver
as if to make a telephone call and attempt dialling in the tone dial
mode. If after dialling a digit you find that the dial tone has been
removed from the line, you are on a tone dial line. If not, you are on a
pulse dial line. Repeat the above in the pulse dial mode to confirm.
