battery terminals.

– Replace the battery only with another battery that has been qualified with 

the device per this standard, IEEE-Std-1725-2006. Use of an unqualified 
battery may present a risk of fire, explosion, leakage or other hazard.

– Promptly dispose of used batteries in accordance with local regulations.
– Battery usage by children should be supervised.
– 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.

– Use your battery for the specified purpose only.
– The closer you are to your network’s base station, the longer your phone 

usage time because less battery power is consumed for the connection.

– The battery recharging time varies depending on the remaining battery 

capacity and the battery and charger type you use.

– Battery life inevitably shortens over time.
– Use an authorized battery and charger only.
– Since overcharging may shorten battery life, remove the phone from 

its charger once it is fully charged. Unplug the charger, once charging is 
complete. Leaving the battery in hot or cold places, especially inside a car in 
summer or winter, may reduce the capacity and life of the battery. Always 
keep the battery within normal temperatures.

– To prevent injury or burns, ensure that no metal objects come into contact 

with the + and – terminals of the battery.

On July 10, 2003, the U.S. Federal Communications Commission (FCC) Report 
and Order in WT Docket 01-309 modified the exception of wireless phones 
under the Hearing Aid Compatibility Act of 1988 (HAC Act) to require digital 
wireless phones be compatible with hearing-aids.
The intent of the HAC Act is to ensure reasonable access to telecommunications 
services for persons with hearing disabilities.
While some wireless phones are used near some hearing devices (hearing aids 
and cochlear implants), users may detect a buzzing, humming, or whining 
noise. Some hearing devices are more immune than others to this interference 
noise, and phones also vary in the amount of interference they generate.
The wireless telephone industry has developed a rating system for wireless 
phones, to assist hearing device users find phones that may be compatible 
with their hearing devices. Not all phones have been rated. Phones that are 
rated have the rating on their box or a label located on the box.
The ratings are not guarantees. Results will vary depending on the user’s 
hearing device and hearing loss. If your hearing device happens to be 
vulnerable to interference, you may not be able to use a rated phone 
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
