• Consult the dealer or an experienced radio/TV technician for help. The country code selection is for non-US models only and is not available to all US models. Per FCC regulation, all WiFi products that are marketed in US must be fixed to US-operated channels only. Hearing Aid Compatibility Information (HAC) Your phone is compliant with the FCC Hearing Aid Compatibility requirements. The FCC has adopted HAC rules for digital wireless phones. These rules require certain phone to be tested and rated under the American National Standard Institute (ANSI) C63.19-2011 hearing aid compatibility standards. The ANSI standard for hearing aid compatibility contains two types of ratings: M-Ratings: Rating for less radio frequency interference to enable acoustic coupling with hearing aids. T-Ratings: Rating for inductive coupling with hearing aids in telecoil mode. Not all phones have been rated, a phone is considered hearing aid compatible under FCC rules if it is rated M3 or M4 for acoustic coupling and T3 or T4 for inductive coupling. These ratings are given on a scale from one to four, where four is the most compatible. Your phone meets the M4/ T4 level rating. However, hearing aid compatibility ratings don't guarantee that interference to your hearing aids won't happen. Results will vary, depending on the level of immunity of your hearing device and the degree of your 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. E12327_ZS571KL_UM_Booklet_EU.indd 9 2017/3/17 15:14:39
