successfully. Trying out the phone with your hearing device is the best way
to evaluate it for your personal needs.
M-Ratings: Phones rated M3 or M4 meet FCC requirements and are likely to
generate less interference to hearing devices than phones that are not
labeled. M4 is the better/higher of the two ratings.
T-Ratings: Phones rated T3 or T4 meet FCC requirements and are likely to be
more usable with a hearing device’s telecoil (“T Switch” or “Telephone
Switch”) than unrated phones. T4 is the better/higher of the two ratings.
(Note that not all hearing devices have telecoils in them.)
Hearing devices may also be measured for immunity to this type of
interference. Your hearing device manufacturer or hearing health A-18
Hearing Aid Compatibility professional may help you find results for your
hearing device. The more immune your hearing aid is, the less likely you are
to experience interference noise from mobile phones.
Battery Tips
ⅷ Battery life depends on the network, signal strength, temperature,
features, and accessories you use.
ⅷ Always use Motorola Original batteries and chargers. The
warranty does not cover damage caused by non-
Motorola batteries and/or chargers.
ⅷ New batteries or batteries stored for a long time may
take more time to charge.
ⅷ When charging your battery, keep it near room temperature.
ⅷ When storing your battery, keep it uncharged in a cool, dark, dry place.
ⅷ Never expose batteries to temperatures below -10°C (14°F) or above
45°C (113°F). Always take your phone with you when you leave your
vehicle.
ⅷ It is normal for batteries to gradually wear down and require longer
charging times. If you notice a change in your battery life, it is probably
time to purchase a new battery.
Contact your local recycling center for proper battery disposal.
Warning: Never dispose of batteries in a fire because they may
explode.
Before using your phone, read the battery safety information in the “Safety
and General Information” section included in this guide.
