Vibrating Alert
The unit is equipped with a .5mm vibrating alert jack for an
optional vibrating pad to alert you when the phone is ringing.
Simply plug the vibrating alert into the jack . When the phone
rings, the pad will vibrate with each ring of the phone.
Flash
Press the EXIT/FLASH button to activate customer calling
services such as call waiting or call transfer, which are
provided by your local phone company.
Redial
You may redial the last number you called by pressing the
REDIAL button after you get a dial tone.
NOTE: The Redial feature holds in memory the
last phone number you dialed (as many as
32 digits). If you pressed any numbers after
dialing the phone number, (for example, when
accessing a voice-menu system) those numbers
also are redialed.
