To disconnect one party from a conference call and keep the other on the
line, press the line button of the call you want to continue.
NOTE: If you leave the F button down after a conference call, then dial
another number, your call might be completed, but you might hear a busy
signal from the other line. Press
H, then press each line button until
you identify the line being used for your completed call.
Flash
The F button is useful if you have subscribed to custom calling services
from your local telephone company. Press F instead of pressing the
switchhook to activate services such as Call Waiting or 3-Way Calling.
You may have to press other buttons before or after F as explained in the
custom calling instructions provided by your local telephone company. The
F button is used only as a substitute for pressing the switchhook.
Temporary Tone
If you have dial pulse (rotary) service, you can change from pulse to tone
dialing during a call by pressing t. This is useful if you need to send
tone signals to access telephone banking or long-distance services.
1 Dial the telephone number.
2 Press t. All buttons pressed after this send tone signals.
3 After you hang up, the phone returns to pulse dialing.
Ringer Volume
This phone has two separate RINGER switches, one for each telephone line.
You can set each switch to OFF, LO or HI. You can dial and answer calls
normally with one or both switches set to OFF.
Other telephones in your home will still ring; they are not affected by the
switches on this phone. If this is the only telephone in your home, you will
not hear any incoming calls while both ringers are off. However, the light
next to one of the line buttons will always flash when you have a call.
Receiver (Handset) Volume
Use the receiver VOLUME switch on the side of the phone to adjust the
handset volume to a comfortable listening level.
