Using Your USB Stick
• Use original accessories or accessories that are authorized.
Using any unauthorized accessories may aect the performance
of the modem and violate the related national regulations about
telecom terminals.
• Avoid using the modem near or inside metallic structures or
establishments that can emit electromagnetic waves, because
signal reception may be aected.
• The modem is not waterproof. Keep the modem dry and store it
in a shady and cool place.
• Do not use the modem immediately aer a sudden temperature
change. In such case, dew may be generated inside and outside
the modem, so do not use it until it becomes dry.
• Handle the modem carefully. Do not drop, bend or strike it.
Otherwise the modem may be damaged.
• Only qualied personnel can dismantle and repair the modem.
• An operating temperature between -10°C (14°F) and +55°C
(131°F) and a humidity between 5% and 95% are recommended.
RF Exposure Information (SAR)
This device meets the government’s requirements for exposure to
radio waves.
This device is designed and manufactured not to exceed the
emission limits for exposure to radio frequency (RF) energy set by
the Federal Communications Commission of the U.S. Government.
The exposure standard for wireless devices employs a unit of
measurement known as the Specic Absorption Rate, or SAR.
The SAR limit set by the FCC is 1.6 W/kg.
Tests for SAR are conducted using standard operating positions
accepted by the FCC with the device transmitting at its highest
certied power level in all tested frequency bands. Although the
SAR is determined at the highest certied power level, the actual
SAR level of the device while operating can be well below the
maximum value. This is because the device is designed to operate
at multiple power levels so as to use only the power required to
reach the network. In general, the closer you are to a wireless base
station antenna, the lower the power output.
The device was tested according to FCC RF exposure procedures
to address hand and near-body exposure conditions, and the
highest SAR value as reported to the FCC is 1.40 W/kg.
While there may be dierences between the SAR levels of various
devices and at various positions, they all meet the government
requirement.
The FCC has granted an Equipment Authorization for this device
with all reported SAR levels evaluated as in compliance with the
FCC RF exposure guidelines. SAR information on this device is on le
