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 suggest 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.
Getting the Best Hearing Device Experience With Your Device
To further minimize interference:
ⅷ
Set the phone's screen and keyboard backlight settings to ensure the minimum time
interval.
ⅷ
Move the phone around to find the point with the least interference.

Protecting Your Battery
The guidelines listed below help you get the most out of your battery's performance.
Recently there have been some public reports of wireless phone batteries overheating,
catching fire, or exploding. It appears that many, if not all, of these reports involve counterfeit
or inexpensive, aftermarket-brand batteries with unknown or questionable manufacturing
standards. Use only manufacturer-approved batteries and accessories found at Carrier Stores
or through your device's manufacturer. Buying the right batteries and accessories is the best
way to ensure they are genuine and safe.

In order to avoid damage, charge the battery only in temperatures that range from 32° F to
122° F (0° C to 50° C).
