Safety Information

Before you use your Trimble product, make sure that you have read and understood all
safety requirements.

WARNING – This alert warns of a potential hazard which, if not avoided, could

result in severe injury or even death.

CAUTION – This alert warns of a potential hazard or unsafe practice that could

result in minor injury or property damage or irretrievable data loss.

NOTE – An absence of specific alerts does not mean that there are no safety risks involved.

Use and care

This product is designed to withstand the rough treatment and tough environment that
typically occurs in construction applications. However, the receiver is a high-precision
electronic instrument and should be treated with reasonable care.

CAUTION – Operating or storing the receiver outside the specified temperature

range can damage it.

Regulations and safety

Some receiver models with base station capability contain an internal radio-modem for
transmission or can transmit through an external data communications radio. Regulations
regarding the use of the 410 MHz to 470 MHz 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
Trimble dealer.

NOTE – The SPS986 uses the 403 MHz to 473 MHz frequency range.

All Trimble receiver models described in this documentation are capable of transmitting
data through Bluetooth wireless technology.

Bluetooth wireless technology, and 900 MHz radio-modems and 2.4 GHz radio-modems
operate in license-free bands.

NOTE – 900 MHz radios are not used in Europe. The frequency range of 900 MHz is not marketed

in Brazil.

SPS986 GNSS Smart Antenna Getting Started Guide | 5

Safety Information

Before operating a Trimble receiver or GSM modem, determine if authorization or a license
to operate the unit is required in your country. It is the responsibility of the end user to
obtain an operator's permit or license for the receiver for the location or country of use.

For FCC regulations, see Notices.

Type approval

Type approval, or acceptance, covers technical parameters of the equipment related to
emissions that can cause interference. Type approval is granted to the manufacturer of
the transmission equipment, independent from the operation or licensing of the units.
Some countries have unique technical requirements for operation in particular radio­modem frequency bands. To comply with those requirements, Trimble may have modified
your equipment to be granted type approval.

Unauthorized modification of the units voids the type approval, the warranty, and the
operational license of the equipment.

Exposure to radio frequency radiation

SPS986 (with internal 450 MHz radio operating in base station transmit mode). Note the
safe distance is 32 cm (1 foot) for RF Exposure.

For 450 MHz radio

Safety. Exposure to RF energy is an important safety consideration. The FCC has adopted a
safety standard for human exposure to radio frequency electromagnetic energy emitted
by FCC regulated equipment as a result of its actions in General Docket 79-144 on March
13, 1986.

Proper use of this radio modem results in exposure below government limits. The
following precautions are recommended:

l DO NOT operate the transmitter when someone is within 25 cm (9.8 inches) of the

antenna.

l DO NOT co-locate (place within 45 cm (17.7 inches)) the radio antenna with any other

transmitting antenna.

l DO NOT operate the transmitter unless all RF connectors are secure and any open

connectors are properly terminated.

l DO NOT operate the equipment near electrical blasting caps or in an explosive

atmosphere.

SPS986 GNSS Smart Antenna Getting Started Guide | 6

l All equipment must be properly grounded according to Trimble installation

instructions for safe operation.

l All equipment should be serviced only by a qualified technician.

For license-free 900 MHz radio

CAUTION – For your own safety, and in terms of the RF exposure requirements of

the FCC, always observe these precautions:

l Always maintain a minimum separation distance of 25 cm (9.8 inches) between

yourself and the radiating antenna.

l Do not co-locate the antenna with any other transmitting device.

NOTE – 900 MHz radios are not used in Europe.

For Bluetooth radio

Safety Information

The radiated output power of the internal Bluetooth wireless radio and the Wi-Fi radio
included in some Trimble receivers is far below the FCC radio frequency exposure limits.
Nevertheless, the wireless radio(s) shall be used in such a manner that the Trimble receiver
is 25 cm or further from the human body. The internal wireless radio(s) operate within
guidelines found in radio frequency safety standards and recommendations, which reflect
the consensus of the scientific community. Trimble therefore believes that the internal
wireless radio(s) are 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 turning on the wireless radio.

Installing antennas

CAUTION – For your own safety, and in terms of the RF exposure requirements of

the FCC, always observe these precautions:

l Always maintain a minimum separation distance of 25 cm (9.8 inches) between

yourself and the radiating antenna.

l Do not co-locate the antenna with any other transmitting device.

SPS986 GNSS Smart Antenna Getting Started Guide | 7

Safety Information

WARNING – The GNSS antenna and its cabling should be installed in accordance

with all national and local electrical codes, regulations, and practices. The antenna and
cabling should be installed where they will not become energized as a result of falling
nearby power lines, nor be mounted where they are subjected to over-voltage
transients, particularly lightning. Such installations require additional protective means
that are detailed in national and local electrical codes.

Trimble receiver internal radios have been designed to operate with the antennas listed
below. Antennas not included in this list are strictly prohibited for use with this device. The
required antenna impedance is 50 ohms.

To reduce potential radio interference to other users, the antenna type and its gain should
be an approved Trimble antenna, so that the equivalent isotropically radiated power
(e.i.r.p.) is not more than that permitted for successful communication.
