Safety and general information
Important information on safe and efficient use of your Radio device
Exposure to radio frequency energy
Your modem is a high power radio transceiver. When it is on, it receives and also
sends out radio frequency (RF) signals. To help minimize human exposure to RF
electromagnetic energy, keep transmission time to 50% or less.
As with all radio devices, holding the antenna affects transmission quality and
may cause the radio to operate at a higher power level than required. Do not hold
the antenna when the radio is in use.
Do not use radios with damaged or modified antenna, this may violate
compliance with relevant international standards.
Where prolonged human exposure is likely, the minimum separation from the
antenna should be 0.8m.
Electromagnetic interference/compatibility
Most modern electronic equipment is shielded from RF energy. However certain
electronic equipment may not be shielded against RF signals. The modem needs
to be switched off in any facility where posted notices instruct you to do so to
avoid electromagnetic interference or compatibility conflicts. Special care should
be taken near facilities such as hospitals or health care centers may be using
equipment that is sensitive to external RF energy.
Medical devices (Pacemakers)
If you use any personal medical device, consult the manufacturer of your device
to determine it is adequately shielded from RF energy. Your physician may be
able to assist you in obtaining this information.
