that has no connection to mains power.
5
Only use original accessories supplied by the manufacturer. Using
unauthorised accessories may invalidate your warranty.
Avoid using the USB modem near or inside metallic structures or
establishments that can emit electromagnetic waves.

Health and safety information
Radio Frequency (RF) Energy
This model phone meets the government’s requirements for exposure to radio waves.
This phone 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 USB modem employs a unit of measurement
known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is
1.6W/kg. *Tests for SAR are conducted using standard operating positions accepted
by the FCC with the phone transmitting at its highest certified power level in all tested
frequency bands. Although the SAR is determined at the highest certified power
level, the actual SAR level of the phone while operating can be well below the
maximum value. This is because the phone is designed to operate at multiple power
levels so as to use only the poser required to reach the network. In general, the
closer you are to a wireless base station antenna, the lower the power output.
The highest SAR value for the USB modem as reported to the FCC when tested for
use at body is 1.18 W/kg.
While there may be differences between the SAR levels of various phones and at
various positions, they all meet the government requirement.
The FCC has granted an Equipment Authorization for this model phone with all
reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines.
SAR information on this model phone is on file with the FCC and can be found under
the Display Grant section of http://www.fcc.gov/oet/fccid after searching on
FCC ID: Q78-MF668A
FCC Compliance （only Part 15B）

Caution: Changes or modifications not expressly approved by the manufacturer
could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
