What's this notification icon?

[TJH132]

After playing around with my DInc today, I noticed a new icon in the notification bar. I'm having a hard time figuring it out and I can't remember what setting I might have switched on. I found a chart of icons and this one isn't listed. Here's a small .jpg; it's the one on the far left.

Thanks,

TJH

looks like its paired with a bluetooth headset.

Haha, I remember this coming up on the precentral forums about a year ago, and no one knew what it meant on their Pre. I don't remember exactly because it didn't mean much. I know that's not much help at all. I want to say it had something to do with universal access (as in for hearing impaired people) or something like that. I honestly can't remember though :/

Could it be Text to Speech maybe? Maybe TTY Mode? Hearing Aid Compatibility (HAC) mode?

It has something to do with "Accessibility" for the disabled.

It's the 'hearing aides' setting from the 'call' preferences.

This icon was driving me nuts... not in any manual I could find online. Thanks!!
