Section 8A: Safety

hearing aid. Add the rating of your hearing aid and your phone to determine probable 
usability:

䢇

Any combined rating equal to or greater than six offers best use.

䢇

Any combined rating equal to five is considered normal use.

䢇

Any combined rating equal to four is considered usable.

Thus, if you pair an M3 hearing aid with an M3 phone, you will have a combined rating of 
six for “best use.” This is synonymous for T ratings. 

Palm further suggests that you experiment with multiple phones (even those not labeled 
M3/T3 or M4/T4) while in the store to find the one that works best with your hearing aid 
device. If you experience interference or find the quality of service unsatisfactory after 
purchasing your device, promptly return it to the store within 30 days of purchase. With 
the Palm 30-day Risk-Free Guarantee, you may return the device within 30 days of 
purchase for a full refund, and you will only be responsible for charges based on your actual 
usage.

To further minimize interference: 

䢇

There is usually less interference on the microphone setting than on the telecoil 
setting.

䢇

Set the phone’s screen and keyboard backlight settings to ensure the minimum time 
interval. 

䢇

Move the phone around to find the point with the least interference.

䢇

If your hearing aid is equipped with a telecoil, turn on the HAC setting on your device.

When 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. Turn off your
