Palm TREOPROBLKSPT User Manual

to those of phones. Ask your hearing health-care professional for the rating of your 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 the 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 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.

To further minimize interference:

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

Do not disassemble or open, crush, bend or deform, puncture or shred.

䢇

Do not modify or remanufacture, attempt to insert foreign objects into the battery, immerse 
or expose to water or other liquids, or expose to fire, explosion, or other hazard. 

䢇

Only use the battery for the system for which it is specified. 

䢇

Only use the battery with a charging system that has been qualified with the system per 
the IEEE/CTIA-1725 standard. Use of an unqualified battery or charger may present a risk 
of fire, explosion, leakage, or other hazard.
