RADIO FREQUENCY SAFETY INFORMATION:
IMPORTANT: To satisfy radio frequency exposure compliance requirements, the antenna and transmitter in the
ViA codec, or cellular module antennas/transmitters, must be at least 20 cm from all persons and must not be
used in conjunction with any other antennas or transmitters. Only use the product with the supplied antenna/s.
Failure to adhere this may result in the product exceeding RF exposure limits and may void the user’s
authorization to operate the equipment.
The device has an internal Wi-Fi antenna which is located at the rear of the unit. For optimumperformance with
minimumpower consumption do not shield the device or cover w ith any object. Covering the antenna affects
signal quality, may cause the product to operate at a higher power level than needed, and may shorten battery
life.
Due to the possibility of radio frequency (RF) interference, it is important that you follow any special regulations
regarding the use of radio equipment. Follow the safety advice:
·Operating your device close to other electronic equipment may cause interference if the equipment is
inadequately protected. Observe any warning signs and manufacturers’ recommendations.
·Different industries and businesses restrict the use of cellular devices. Respect restrictions on the use
of radio equipment in fuel depots, chemical plants, or w here blasting operations are in process. Follow
restrictions for any environment where you operate the device.
·Do not place the antenna outdoors.
·Switch OFF your wireless device w hen in an aircraft. Using portable electronic devices in an aircraft
may endanger aircraft operation, disrupt the cellular network, and is illegal. Failing to observe this

Interference with Pacemakers and Other Medical Devices
Potential interference:
Radio frequency energy (RF) from cellular devices can interact with some electronic devices. This is
electromagnetic interference (EMI). The FDA helped develop a detailed test method to measure EMI of implanted
cardiac pacemakers and defibrillators fromcellular devices. This test method is part of the Association for the
Advancement of Medical Instrumentation (AAMI) standard. This standard allows manufacturers to ensure that
cardiac pacemakers and defibrillators are safe from cellular device EMI. The FDA continues to monitor cellular
devices for interactions with other medical devices. If harmful interference occurs, the FDA will assess the
interference and work to resolve the problem.
Precautions for pacemaker wearers:
If EMIoccurs, it could affect a pacemaker in one of three ways:
·Stop the pacemaker fromdelivering the stimulating pulses that regulate the heart's rhythm.
·Cause the pacemaker to deliver the pulses irregularly.
·Cause the pacemaker to ignore the heart's own rhythmand deliver pulses at a fixed rate.
Based on current research, cellular devices do not pose a significant health problem for most pacemaker
wearers. However, people w ith pacemakers may want to take simple precautions to be sure that their device
doesn't cause a problem.
·Keep the device on the opposite side of the body fromthe pacemaker to add extra distance between the
pacemaker and the device.
·Avoid placing a turned-on device next to the pacemaker (for example, don’t carry the device in a shirt or
jacket pocket directly over the pacemaker).
Vehicle Safety
When using your device in a vehicle:
·Do not use this device while driving.
·Respect national regulations on the use of cellular devices in vehicles.
·If incorrectly installed in a vehicle, operating the wireless device could interfere with the vehicle’s
electronics. To avoid such problems, use qualified personnel to install the device. The installer should
verify the vehicle electronics are protected frominterference.
·Using an alert device to operate a vehicle’s lights or horn is not permitted on public roads.
·UL evaluated this device for use in ordinary locations only. UL did NOT evaluate this device for
installation in a vehicle or other outdoor locations. UL Certification does not apply or extend to use
vehicles or outdoor applications or in ambient temperatures above 40° C.

5. Tap Parent Interface to choose the interface from which data will be shared using the Wi-Fi
hotspot.
6. When a device connects successfully the Hotspot symbol changes from greyed out to
