Selecting Your HAC Settings
Your Treo complies with Hearing Aid Compatibility (HAC) standards and includes an HAC
setting. If you use a hearing aid that is equipped with a telecoil and the HAC setting is on,
your device sends the audio from your phone calls to the telecoil rather than to the
microphone of your hearing aid. You are likely to hear calls much better because volume is
increased and background noise and feedback are diminished. The HAC setting improves
only the calls you listen to through the earpiece. It does not affect calls heard on the
speakerphone or with a headset. HAC requires extra battery power, so watch your battery
consumption when it's turned on.
1. Press Start and select Settings.
2. On the Personal tab, select Phone .
3. Select the Services tab and then select Hearing Aid
Compatibility (HAC).
4. Indicate whether you want HAC set to On or Off.
5. Press OK to return to Phone Settings.
6. Press OK to finish.
Controlling Your Roaming Experience
Your device is digital dual-band. This means that you can make and receive calls while on the
Sprint National Network. It also means that you can connect to other digital networks (called
roaming) if Sprint has implemented a roaming agreement with the network provider.
Caution Do not turn on the HAC setting unless you use a hearing aid with a telecoil.
Using this setting without a hearing aid or with a hearing aid without a
telecoil may be harmful to your hearing.
