Any combined rating equal to five is considered normal use.
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 “excellent use.” This is synonymous for T ratings.
It is further suggested 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. Should you experience interference or find the quality of service unsatisfactory after purchasing your phone, promptly return it to the store where purchased for exchange or refund. More information about hearing aid compatibility may be found at: www.fcc.gov, www.fda.gov, and www.accesswireless.org.
Getting the Best Hearing Device Experience With Your Phone

Set the phone’s display and keypad backlight settings to ensure the minimum time interval (see also page 28):
1.Press 
> Settings > Display > Backlight > Backlight Dim or Backlight Off.
2.Highlight the minimum time interval setting and press 
.
Position the phone so the internal antenna is farthest from your hearing aid.
Move the phone around to find the point with least interference.
Caring for the Battery
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. The manufacturer is not aware of similar problems with manufacturer phones resulting from the proper use of batteries and accessories approved by the manufacturer of your phone. Use only manufacturer- approved batteries and accessories found through your phone’s manufacturer. Buying the right batteries and accessories is the best way to ensure they’re genuine and safe.
Do not disassemble or open crush, bend or deform, puncture or shred the battery.
Do not modify or remanufacture, attempt to insert foreign objects into the battery, immerse or expose to water or other liquids, expose to fire, explosion or other hazard.
Avoid dropping the phone or battery. If the phone or battery is dropped, especially on a hard surface, and the user suspects damage, take it to a service center for inspection.
Improper battery use may result in a fire, explosion or other hazard.
Do not short circuit a battery or allow metallic conductive objects to contact battery terminals.
Keep the metal contacts on top of the battery clean.
Battery usage by children should be supervised.
