The standard for hearing aid compatibility contains two types of ratings:
M: To use your hearing aid in this mode, make sure that your hearing aid is set to
•
"M-mode" or acoustic coupling mode, and position the phones receiver near the
hearing aid's built-in microphone. For the best results, try using the phone in differ-
ent positions relative to your hearing aid—for example, placing the receiver slightly
above the ear may result in better performance for hearing aids with microphones
positioned behind the ear.
•
T: To use your hearing aid in this mode, make sure that your hearing aid is set to "T-
mode" or telecoil coupling mode (not all hearing aids have this mode). For the best
results, try using the phone in different positions relative to your hearing aid—for ex-
ample, placing the receiver slightly below or in front of the ear may result in better
performance.
Your device meets the M4/T4 level rating.
Specific Absorption Rate (SAR)
This device meets applicable international safety requirements for exposure to radio
waves. Your mobile device is a radio transmitter and receiver. It is designed not to exceed
the limits for exposure to radio waves (radio frequency electromagnetic fields) recommen-
ded by international guidelines from the independent scientific organization ICNIRP (In-
ternational Commission of Non-Ionizing Radiation Protection).
The radio wave exposure guidelines use a unit of measurement known as the Specific Ab-
sorption Rate, or SAR. The SAR limit for mobile devices is 2 W/kg averaged over 10 grams
of tissue and include a substantial safety margin designed to assure the safety of all per-
sons, regardless of age and health.
Tests for SAR are conducted using standard operating positions with the device transmit-
ting at its highest certified power level in all tested frequency bands. The highest SAR val-
ues under the ICNIRP guidelines for this device model are:
Head SAR: 0.595 W/kg
Body SAR: 1.499 W/kg
During normal use, the SAR values for this device are usually well below the values stated
above. This is because, for purposes of system efficiency and to minimize interference on
the network, the output power of your mobile device is automatically decreased when full
power is not needed for the call. The lower the power output of the device, the lower its
SAR value.
This device meets RF exposure guidelines when used against the head or when positioned
at least 0.5 cm away from the body. When a carry case, belt clip or other form of device
holder is used for body-worn operation, it should not contain metal and should provide at
least the above stated separation distance from the body.
The World Health Organization (WHO) has stated that current scientific information does
not indicate the need for any special precautions when using mobile devices. If you are in-
terested in reducing your exposure, they recommend you reduce your usage or use a
hands-free accessory to keep the device away from your head and body.
