M-Ratings: Phones rated M3 or M4 meet FCC requirements and are likely to generate less
interference with 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 be more usable
with a hearing device's telecoil ("T Switch" or "Telephone Switch") than unrated phones.
T4 is the better/higher of the two ratings.
Important: This device does not support VoIP. WLAN and Bluetooth do not have voice
capability for held-to-the-ear phone service.
Note: Not all hearing devices contain telecoils.
The more immune your hearing aid device is, the less likely you are to experience
interference noise from your wireless phone. Hearing aid devices should have ratings
similar to those of phones. Ask your hearing health-care professional for the rating of
your hearing aid.
Hearing devices may also be measured for immunity to this type of interference. Your
hearing device manufacturer or hearing health professional may help you find results for
your hearing device. The more immune your hearing aid is, the less likely you are to
experience interference noise from wireless devices.

Certificate Information (SAR)
This device meets the EU requirements (1999/519/EC) on the limitation of exposure of the
general public to electromagnetic fields by way of health protection.
The limits are part of extensive recommendations for the protection of the general
public. These recommendations have been developed and checked by independent
scientific organizations through regular and thorough evaluations of scientific studies. To
guarantee the safety of all persons, regardless of age and health, the limits include a
significant safety buffer.
Before radio devices can be put in circulation, their agreement with European laws or
limits must be confirmed; only then may the CE symbol be applied.
The unit of measurement for the European Council's recommended limit for mobile
telephones is the "Specific Absorption Rate" (SAR). This SAR limit is 2.0 W/kg, averaged
over 10 g of body tissue. It meets the requirements of the International Commission on
Non-Ionizing Radiation Protection (ICNIRP) and was included in the European Standard
EN 50360 for mobile radio devices. The SAR regulation for mobile telephones is in line
with European Standard EN 62209-1. The maximum SAR value is calculated at the highest
output level in all frequency bands of the mobile telephone. During use, the actual SAR
level is usually much lower than the maximum value, because the mobile telephone
works in different output levels. It only transmits with as much output as is required to
