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 gateway is used in a normal manner with a well-constructed network, the
gateway 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. Robustel
accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or received
using the gateway, or for failure of the gateway to transmit or receive such data.
Safety Precautions
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,
etc.
An external antenna must be connected to the gateway for proper operation. Only uses approved antenna with
the gateway. Please contact authorized distributor on finding an approved antenna.
Always keep the antenna with minimum safety distance of 20 cm or more from human body. Do not put the
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.
Gateway may be used at this time.
Using the gateway in Vehicle
Check for any regulation or law authorizing the use of cellular devices in vehicle in local country before installing
the gateway.
The driver or operator of any vehicle should not operate the gateway while driving.
Install the gateway by qualified personnel. Consult your vehicle distributor for any possible interference of
electronic parts by the gateway.
The gateway should be connected to the vehicle’s supply system by using a fuse-protected terminal in the
vehicle’s fuse box.
Be careful when the gateway is powered by the vehicle’s main battery. The battery may be drained after
extended period.
