... GENERAL DESCRIPTION The W91550DN series are Si-gate CMOS IC tone/pulse switchable dialers containing 13 number memories and a 10-digit LCD driver for displaying telephone numbers and calling time, including a 16-digit 3 one-touch memory, 16-digit save memory. These dialers also provide a secrecy key, flash, two-way handfree dialing, one-key redial, hold and lock functions ...
