4. Certif ication and Compliance
Sero contains radio transmitters and receivers. When on, Sero sends and
receives radio frequency (RF) energy through its antenna. The WLAN and
Bluetooth® antenna is located
11
in back view of “Get to know your Sero”. Sero
has been tested and meets the SAR exposure requirements for WLAN and
Bluetooth operation.
Sero is designed and manufactured to comply with the limits for exposure to
RF energy set by the Federal Communications Commission (FCC) of the United
State. The exposure standard employs a unit of measurement known as the
specic absorption rate, or SAR. The SAR limit applicable to Sero set by the FCC
is 1.6 watts per kilogram (W/kg). Tests for SAR are conducted using standard
operating positions specied by these agencies, with Sero transmitting at its
highest certified power level in all tested frequency bands. Although SAR is
determined at the highest certied power level in each frequency band, the
actual SAR level of Sero while in operation can be well below the maximum
value because Sero adjusts its WLAN transmitting power based in part on
orientation and proximity to the wireless network. In general, the closer you are
to a WLAN Router, the lower the WLAN transmitting power level.
Sero has been tested, and meets the FCC RF exposure guidelines for WLAN and
Bluetooth operation. When tested at direct body contact, Sero’s maximum SAR
value for each frequency band is outlined below:
FCC SAR
Frequency Band (MHz) FCC 1g SAR Limit (W/kg) Highest Value (W/kg)
Model: M470BSA
2412-2462 1.6 1.059
5180-5240 1.6 0.7987
5260-5320 1.6 0.751
5745-5805 1.6 0.692
