Safety Precautions
The following topics outline important safety precautions that must be observed when using your device.
Important Notice
Due to the nature of wireless communications, transmission and reception of data can never be
guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant
delays or losses of data are rare when wireless devices such as the Sprint Pocket Wi-Fi are used in a
normal manner with a well-constructed network, your device should not be used in situations where
failure to transmit or receive data could result in damage of any kind to the user or any other party,
including but not limited to personal injury, death, or loss of property. Sprint accepts no responsibility for
damages of any kind resulting from delays or errors in data transmitted or received using your device, or
for failure of your device to transmit or receive such data.
Safety and Hazards
Do not operate your device under the following conditions.
● In areas where blasting is in progress
● Where explosive atmospheres may be present
● Near medical equipment
● Near life support equipment, or any equipment that may be susceptible to any form of radio
interference.
In such areas, your device MUST BE POWERED OFF. Your device can transmit signals that could
interfere with this equipment.
Do not operate your device in any aircraft, whether the aircraft is on the ground or in flight. In aircraft, your
device MUST BE POWERED OFF. When operating, your device can transmit signals that could interfere
with various onboard systems.
Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door
is open. Your device may be used at this time.
The driver or operator of any vehicle should not operate the device while in control of a vehicle. Doing so
will detract from the driver or operator’s control and operation of that vehicle. In some jurisdictions,
operating such communications devices while in control of a vehicle is an offense.

The following topics detail the specific absorption rate (SAR) information, electromagnetic safety
information, and radiofrequency (RF) exposure information for this device.
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 United States.

During SAR testing, this device is set to transmit at its highest certified power level in all tested frequency
bands, and placed in positions that simulate RF exposure in usage against, and near the body with the
separation of 5 mm. Although the SAR is determined at the highest certified power level, the actual SAR
level of the 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. Safety and Notices 90
The exposure standard for wireless 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
device transmitting at its highest certified power level in all tested frequency bands.
The FCC has granted an Equipment Authorization for this model device with all reported SAR levels
evaluated as in compliance with the FCC RF exposure guidelines. SAR information on this model device
is on file with the FCC and can be found under the Display Grant section of
https://www.fcc.gov/general/fcc-id-search-page after searching on FCC ID: XHG-U772S
More information on the device's SAR can be found from the following FCC website:
https://www.fcc.gov/general/fcc-id-search-page.
While there may be differences between the SAR levels of various devices and at various positions, they
all meet the government requirement.
Body-Worn Operation
Please note this important safety information regarding radio frequency (RF) radiation exposure and near-
body operation. To ensure compliance with RF exposure guidelines, the device must be used at least 5
mm from your body. Failure to observe this warning could result in RF exposure exceeding the applicable
guideline limits.
