To reduce risk of fire or burns, do not disassemble, crush, puncture, short circuit the external contacts, expose to temperature above 113F
(45C), or dispose of in fire or water. Do not attempt to replace the non-
removable battery. The phone and battery as a unibody device must be disposed of in accordance with locally applicable environmental regulations or guides supplied with your product . 51 Take extra precautions Do not disassemble or open crush, bend or deform, puncture or shred . Do not short circuit a battery or allow metallic conductive objects to contact battery terminals . Only use the USB cable provided with the phone or that bear the USB-IF logo or have completed the USB-IF compliance program . 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 hazards. Device usage by children should be supervised . Only use the battery with a charging system that has been qualified with the system per CTIA Certification Requirement for Battery System Compliance to IEEE1725. Use of an unqualified battery or charger may present a risk of fire, explosion, leakage, or other hazards . 52 Avoid dropping the phone . If the phone 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 hazards. If the battery leaks:
Do not allow the leaking fluid to come in contact with skin or clothing. If already in contact, flush the affected area immediately with clean water and seek medical advice . Do not allow the leaking fluid to come in contact with eyes. If already in contact, DO NOT rub; rinse with clean water immediately and seek medical advice . Take extra precautions to keep a leaking battery away from fire as there is a danger of ignition or explosion . 53 Hearing Aid Compatibility (HAC) for Wireless Telecommunication Devices This phone has a HAC rating of M4/T4. What is hearing aid compatibility?
The Federal Communications Commission has implemented rules and a rating system designed to enable people who wear hearing aids to more effectively use these wireless telecommunications devices. The standard for compatibility of digital wireless phones with hearing aids is set forth in American National Standard Institute (ANSI) standard C63.19. There are two sets of ANSI standards with ratings from one to four (four being the best rating): an M rating for reduced interference making it easier to hear conversations on the phone when using the hearing aid microphone, and a T rating that enables the phone to be used with hearing aids operating in the telecoil mode thus reducing unwanted background noise . 54 How will I know which wireless phones are hearing aid compatible?
The Hearing Aid Compatibility rating is displayed on the wireless phone box. A phone is considered Hearing Aid Compatible for acoustic coupling
(microphone mode) if it has an M3 or M4 rating. A digital wireless phone is considered Hearing Aid Compatible for inductive coupling
(telecoil mode) if it has a T3 or T4 rating.
