hearing health professional may help you find this rating. Higher ratingsmean 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 isconsidered for best use.In the above example, if a hearing aid meets the M2 level rating and thewireless phone meets the M3 level rating, the sum of the two values equalM5. This is synonymous for T ratings. This should provide the hearing aiduser with “normal usage” while using their hearing aid with the particularwireless phone. “Normal usage” in this context is defined as a signal qualitythat is acceptable for normal operation.The M mark is intended to be synonymous with the U mark. The T mark isintended to be synonymous with the UT mark. The M and T marks arerecommended by the Alliance for Telecommunications Industries Solutions(ATIS). The U and UT marks are referenced in Section 20.19 of the FCCRules. The HAC rating and measurement procedure are described in theAmerican National Standards Institute (ANSI) C63.19 standard.To ensure that the Hearing Aid Compatibility rating for your phone ismaintained, secondary transmitters such as Bluetooth and WLANcomponents must be disabled during a call. See Page XX for instructions todisable these components.FCC Regulatory ComplianceFCC Regulatory ComplianceThis device complies with Part 15 of the FCC Rules. Operation is subject tothe following two conditions: (1) this device may not cause harmfulinterference, and (2) this device must accept any interference received,including interference that may cause undesired operation.Your mobile device is a low power radio transmitter and receiver. When it isON, it receives and also sends out radio frequency (RF) signals. In August1996, the Federal Communications Commission (FCC) adopted RFexposure guidelines with safety levels for mobile devices. Those guidelinesare consistent with safety standards previously set by both U.S. andinternational standards bodies: American National Standard Institute(ANSI), National Council of Radiation Protection andMeasurements(NCRP), and International Commission on Non-IonizingRadiation Protection (ICNRP). Those standards were based oncomprehensive and periodic evaluations of the relevant scientific literature.The design of your phone complies with the FCC guidelines andapplicable.Statement according to FCC part 15.105
