Turning Captions On/Off During a Call

You can turn captions on/o at any time during your call by pressing CAPTIONS (CAPTIONS button). When the blue light around the CAPTIONS button is lit, you will see captions of everything the other party says.

To turn captions off, press CAPTIONS (CAPTIONS button) again. The blue light around the CAPTIONS button goes off.

NOTE: Federal law prohibits anyone but registered users with hearing loss from
using Internet Protocol (IP) Captioned Telephones with the captions turned on.

Adjusting the Volume

You can increase the volume of the person’s voice coming through the handset or speakerphone, up to a 40dB gain from min/max. Watch the lights next to the VOL bar to see what level the volume is set to.

• To increase the volume, press on the VOL button.
• To decrease the volume, press on the VOL button.

The maximum volume setting is very loud. People who do not need amplification should not use the phone at its highest volume setting. The volume level automatically returns to a mid-range setting whenever the phone is hung up.

To save your volume setting so that it will be used during every call, see “Saving Conversation Volume” on page 98.

If you are using a Bluetooth headset, you may be able to control the volume directly on your Bluetooth device. See instructions that came with your Bluetooth device for directions.

Adjusting the Tone Control


You can adjust the Tone of the handset sound to a frequency range that is
better to hear. Use the Tone setting to emphasize HIGH, MEDIUM, or LOW
frequency sound ranges. You can even customize the sound frequency to
match your own audiogram. The setting will remain in e ect until you
change it again.
You can adjust the Tone setting before, during, or after a call.

hearing level.

save your changes or Cancel to exit.
