Hearing Aid Compatibility (HAC)
Your handset has a hearing aid compatibility mode that adjusts the frequency response for
users who have hearing aids equipped with telecoil inductive pickups. Acoustic pickup
hearing aids will not respond to this adjustment. In a call, the minimum volume is 3 and
maximum volume is 8 when HAC is activated.
To View Status of/Enable/Disable HAC
1. Press to enter the main menu.
2. Scroll to Settings, and press .
3. Scroll to Audio, and press .
4. Scroll to HAC, and select between On or Off.
Adjusting Speaker Volume
Adjusting speaker volume can only be done when handset is off hook. The handset will
remember the speaker volume until you make a new adjustment.
During a telephone conversion, you can adjust the speaker volume at any time in relation to
the noise level of the surrounding environment.
Use key placed at the upper left side of handset for volume control.
Note:
Normally, the ear speaker volume has 8 steps (except when using HAC, that only
allows use of step 3-8).
Note:
You can also turn the speakerphone on to use the handset hands free. For more
information, see “Turning Speakerphone Mute On/Off” on page 37.
