General
The gateway generates radio frequency (RF) power. When using the gateway, care must be taken on safety
issues related to RF interference as well as regulations of RF equipment.
Do not use your gateway in aircraft, hospitals, petrol stations or in places where using cellular products is
prohibited.
Be sure that the gateway will not be interfering with nearby equipment. For example: pacemakers or medical
equipment. The antenna of the gateway should be away from computers, office equipment, home appliance,

antenna inside metallic box, containers, etc.
RF exposure statements
1. For mobile devices without co-location (the transmitting antenna is installed or located more than 20cm
away from the body of user and nearby person)
FCC RF Radiation Exposure Statement
1. This Transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
2. This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with a minimum distance of 20 centimeters between the
radiator and human body.
Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door is open.
