Safety Information
This manual describes the A20 GNSS Receiver.
Before you use your receiver make sure that you have read and understood this manual, as
well as all safety requirements.
WARNING
CAUTION
Ignoring this indication and making an operation error could
possibly result in death or serious injury to the operator.
Ignoring this indication and making an operation error could
possibly result in personal injury or property damage.
Regulations and safety
The receivers contain integra Bluetooth wireless technology, and may also send radio
signal through the antenna of an internal radio-modern, or through an externally-connected
data communication radio. Regulations regarding the use of the 460MHz radio-modems
vary greatly from country to country. In some countries, the unit can be used without
obtaining an end-user license. Other countries require end-user licensing. For licensing
information, consult your local FOIF dealer. Bluetooth operates in license-free bands.
Exposure to radio frequency radiation
For radio (410~430MHz/430~450MHz/450~470MHz)
It is safety. Exposure to RF energy is an important safety consideration. Proper use of this
radio modem results in exposure below government limits.
The following precautions are recommended:
lDO NOT operate the transmitter when someone is within 20cm of the antenna.
lDO NOT collocate (place within 20cm) the radio antenna with any other transmitting
lDO NOT operate the transmitter unless all RF connectors are secure and any open
connectors are properly terminated.
lDO NOT operate the equipment near electrical blasting caps or in an explosive atmosphere.
lAll equipment must be properly grounded according to FOIF installation instructions for
safe operation.
lAll equipment should be serviced only by a qualified technician.
For GSM radio
CAUTION
- For your own safety, always observe the precautions listed here.
- Always maintain a minimum separation distance of 20cm between
yourself and the radiating antenna on the radio-modem.
- Do not collocate (place within 20cm) the radio antenna with any
other transmitting antenna.
antenna.
For Bluetooth radio
The radiated output power of the internal Bluetooth wireless radio is far below radio fre-
quency exposure limits. Nevertheless, the wireless radio shall be used in such a manner
that the FOIF receiver is 20cm or further from the human body. The internal wireless radio
operates within guidelines found in radio frequency safety standards and recommendations,
which reflect the consensus of the scientific community. FOIF therefore believes the internal
wireless radio is safe for use by consumers. The level of energy emitted is far less than the
electromagnetic energy emitted by wireless devices such as mobile phones. However, the
use of wireless radios may be restricted in some situations or environments, such as on
aircraft. If you are unsure of restrictions, you are encouraged to ask for authorization before
Installing antennas
CAUTION
- For your own safety, always observe the precautions listed here.
- Always maintain a minimum separation distance of 20cm between
yourself and the radiating antenna.
- Do not collocate (place within 20cm) the radio antenna with any
other transmitting antenna.
turning on the wireless radio.
This device has been designed to operate with the antennas listed below.
UHF Antennas not included in this list, or that have a gain greater than 5dBi, are strictly
prohibited for use with this device. The required antenna impedance is 50 ohms.
The antennas that can be used (country dependent) with the 460 MHz radio are 0dBi and
5dBi whip antennas.
The antenna that can be used with the GSM radio is the 0dBi whip antenna.
To reduce potential radio interference to other users, the antenna type and its gain should
be so chosen that the equivalent isotropic ally radiated power is not more than that permitted
for successful communication.
Rechargeable Lithium-ion batteries
These receivers use a rechargeable Lithium-ion battery.
WARNING
- Do not damages the rechargeable Lithium-ion battery. A damaged
battery can cause an explosion or fire, and can result in personal
injury and /or property damage. To prevent injury or damage:
- Do not use or charge the battery if it appears to be damaged. Signs
of damage include, but are not limited to, discoloration, warping,
and leaking battery fluid.
- Do not expose the battery to fire, high temperature, or direct sun-
- Do not immerse the battery in water.
- Do not use or store the battery inside a vehicle during hot weather.
- Do not drop or puncture the battery.
- Do not open the battery or short-circuit its contacts.
WARNING
- Avoid contact with the rechargeable Lithium-ion battery if it is
appears to be leaking. Battery fluid is corrosive, and contact with it
can result in personal injury and/or property damage.
To prevent injury or damage:
- If the battery leaks, avoid contact with the battery fluid.
- If battery fluid gets into your eyes, immediately rinse your eyes with
clean water and seek medical attention. Do not rub your eyes!
- If battery fluid gets onto your skin or clothing, immediately use
clean water to wash off the battery fluid.
