Hmm, I didn't realize that it could be brushed. Does it beep when it goes to a new program? That's what Freedom does. P1 beeps once, P2 beeps twice, and so on. It does beep a couple times when battery is dying. Then a few minutes later (honestly, i think it has to do with certain maps...stronger map, drain battery quickier), there's multiple beeps then battery dies. It does give me time to locate battery or to switch it out. Although a couple mins seems short, it's enough time.
Yeah, toggling the controls can be a slight pain, but you do get used to it because of the beeps. want to increase volume? Just hold until you hear beep, then click up or down.
Honestly, it does need a bit of work, but Freedom is trying to incorporate all different types of control abilities, and it's kind of hard to make it that simple.
The audiologist can turn off the ability to adjust volume and sensitivity. So, suppose if client likes to adjust the sensitivity, but no need to do for volume, she can turn off the volume, and all you can do is press the buttons for sensitivity. Same goes for volume.
