Trimble R780 GNSS Receiver - Insert the battery

Connect the radio antenna

Connect the radio antenna—P/N 66540-10 (900 MHz) or P/N 44085-60 (450 MHz)—to the TNC connector on the underside of the receiver. Do not over-tighten.
NOTE — The no-radio version of the receiver requires an antenna (P/N 66540-10) for proper Wi-Fi and Bluetooth® radio operation.

Power on/off and LED descriptions

Power on the receiver by pressing and releasing the power button on the front panel.
Power off the receiver by pressing and holding the power button until the Satellite LED turns off, approximately 2 seconds.

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 that, 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 R780 GNSS receiver 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, 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.- Before operating a Trimble receiver, 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.

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.
Exposure to radiofrequency radiation
R780 (with internal 450 MHz radio operating in base station transmit mode). Note the safe distance is 47 cm (18.5 inches) 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 radiofrequency 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:

DO NOT operate the transmitter when someone is within 47 cm (18.5 inches) of the antenna.
DO NOT co-locate (place within 47 cm (18.5 inches)) the radio antenna with any other transmitting antenna.
DO NOT operate the transmitter unless all RF connectors are secure and any open connectors are properly terminated.
DO NOT operate the equipment near electrical blasting caps or in an explosive atmosphere.
All equipment must be properly grounded according to Trimble installation instructions for safe operation.
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:
– Always maintain a minimum separation distance of 20 cm (7.9 inches) between yourself and the radiating antenna.
– Do not co-locate the antenna with any other transmitting device.
NOTE – 900 MHz radios are not used in Europe.

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 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:
– Always maintain a minimum separation distance of 47 cm (18.5 inches) between yourself and the radiating antenna
– Do not co-locate the antenna with any other transmitting device
WARNING – The GNSS and its cabling should be installed in accordance with all national and local electrical codes, regulations, and practices. The 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.
