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 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. C Spire 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

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.
