•
Where explosive atmospheres may be present including refuelling points, fuel
depots, and chemical plants
•
Near medical equipment, life support equipment, or any equipment which
may be susceptible to any form of radio interference. In such areas, the
EM7355 modem MUST BE POWERED OFF. Otherwise, the EM7355 modem
can transmit signals that could interfere with this equipment.
In an aircraft, the EM7355 modem MUST BE POWERED OFF. Otherwise, the
EM7355 modem can transmit signals that could interfere with various onboard
systems and may be dangerous to the operation of the aircraft or disrupt the
cellular network. Use of a cellular phone in an aircraft is illegal in some
jurisdictions. Failure to observe this instruction may lead to suspension or denial
of cellular telephone services to the offender, or legal action or both.
Some airlines may permit the use of cellular phones while the aircraft is on the
ground and the door is open. The EM7355 modem may be used normally at this
time.
Important compliance information for
North American users
Note: Details are preliminary and subject to change.
The EM7355 modem has been granted modular approval for mobile applications.
Integrators may use the EM7355 modem in their final products without additional
FCC / IC (Industry Canada) certification if they meet the following conditions.
Otherwise, additional FCC / IC approvals must be obtained.
1. At least 20 cm separation distance between the antenna and the user's body
must be maintained at all times.
2. To comply with FCC / IC regulations limiting both maximum RF output power
and human exposure to RF radiation, the maximum antenna gain including
cable loss in a mobile-only exposure condition must not exceed:
· 6.5 dBi in Cellular band
· 3.0 dBi in PCS band
· 3.0 dBi in LTE Band 2
· 6.0 dBi in LTE Band 4
· 6.5 dBi in LTE Band 5
· 9.0 dBi in LTE Band 13 (Note: LTE Band 13 is not permitted in Canada.)
· 9.0 dBi in LTE Band 17 (Note: LTE Band 17 is not permitted in Canada.)
· 3.0 dBi in LTE Band 25
3. The EM7355 modem may transmit simultaneously with other collocated radio
transmitters within a host device, provided the following conditions are met:
· Each collocated radio transmitter has been certfied by FCC / IC for mobile
application.
· At least 20 cm separation distance between the antennas of the collocated
transmitters and the user's body must be maintained at all times.
