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.
Regulations and safety
The receivers contain integral Bluetooth® wireless technology, and may also send radio signals
through the antenna of an internal radio-modem, or through an externally-connected data
communications radio. Regulations regarding the use of the 450 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 distribution partner. Bluetooth operates in license-free bands.
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.
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 radio-modem 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.
Trimble R8s GNSS Receiver User Guide 4
Safety Information
Operation near other radio equipment
When operating the receiver in member states of the European Union and in other counties which
adhere to the EU R&TTE requirements, while in the vicinity of aeronautical radionavigation
equipment operating between 2700 and 2900 MHz, or Fixed, Fixed Satellite (space to Earth), or
Mobile systems operating at 4170 MHz, a minimum separation of 5 meters must be maintained
between the receiver and such radio equipment.
Exposure to radio frequency radiation
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 20 cm (7.8 inches) of the antenna.
l
DO NOT co-locate (place within 20 cm (7.8 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.
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 GSM radio
For your own safety, and in terms of the RF Exposure requirements of the FCC, always observe the
precautions listed here.
l Always maintain a minimum separation distance of 20 cm (7.8 inches) between yourself and the
radiating antenna on the receiver radio modem.
l Do not collocate (place within 20 cm) the radio antenna with any other transmitting antenna
Note – The optional GSM radio cannot legally be operated in Brazil.
Trimble R8s GNSS Receiver User Guide 5
Safety Information
For Bluetooth radio
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 20 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:
– Always maintain a minimum separation distance of cm ( inches) between yourself and the radiating antenna.
– Do not co-locate the antenna with any other transmitting device.
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 5 dBi, are strictly prohibited
for use with this device. The required antenna impedance is 50 W..
The antennas that can be used (country dependent) with the 450 MHz radio are 0 dBi and 5 dBi whip
antennas.
The antenna that can be used with the GSM radio is the 0 dBi whip antenna.
To reduce potential radio interference to other users, the antenna type and its gain should be so
chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted for
successful communication.

Trimble R8s GNSS Receiver User Guide 10
1 Introduction
Overview
The receiver incorporates a GNSS antenna, receiver, internal radio with a transmit option or an
internal GSM module, and a battery in a rugged light-weight unit that is ideally suited as an all-onthe-pole RTK rover. Three LEDs allow you to monitor the satellite tracking, radio reception, data
logging status, and power. Bluetooth wireless technology provides cable-free communications
between receiver and controller.
The circuitry in the Trimble R8s GNSS receiver provides up to 440 channels for satellite tracking, and
supports logging raw GNSS observables to the internal receiver memory or to a handheld controller
for postprocessed applications.
The receiver is available in a number of configurations that match the needs of your workflow. This
includes configurations for post-processing workflows, for use as a base station or rover, or for total
flexibility as both a base station and RTK / VRS rover.
Use and care
The receiver can withstand the rough treatment that typically occurs in the field. However, it is a
high-precision electronic instrument and should be treated with reasonable care.
WARNING – Operating or storing the receiver outside the specified temperature range can damage it.
High-power signals from a nearby radio or radar transmitter can overwhelm the receiver circuits.
This does not harm the instrument, but it can prevent the receiver electronics from functioning
correctly. Avoid using the receiver within 400 meters of powerful radar, television, or other
transmitters. Low-power transmitters such as those used in cellphones and two-way radios
normally do not interfere with receiver operations.
For more information, contact your local Trimble distributor.
COCOM limits
The U.S. Department of Commerce requires that all exportable GPS products contain performance
limitations so that they cannot be used in a manner that could threaten the security of the United
States. The following limitations are implemented on the receiver.
Immediate access to satellite measurements and navigation results is disabled when the receiver’s
velocity is computed to be greater than 1000 knots, or its altitude is computed to be above 18,000
meters. The receiver continuously resets until the COCOM situation is cleared.
