LG Electronics MMBB0378701 manual Able to use a rated phone, Your personal needs, Two ratings

Safety

	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
Safety	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 generate less
	interference to hearing devices
114	than phones that are not
	labeled. T4 is the better/higher
	of the two ratings.

Hearing devices may also be rated. Your hearing device manufacturer or hearing health professional may help you find this rating. Higher ratings mean that the hearing device is relatively immune to interference noise. The hearing aid and wireless phone rating values are then added together. A sum of 5 is considered acceptable for normal use. A sum of 6 is considered for best use.
