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 × 10 two-touch memory dialing, and 32-digit × 2 redial and
save memory. These dialers also provide a secrecy key, flash, two-way handfree dialing, one-key
redial, hold and lock functions.
