Safety information

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

This alert warns of a potential hazard which, if not avoided, could result in severe injury or even death.

This alert warns of a potential hazard or unsafe practice that could result in minor injury or property damage or irretrievable data loss.

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.

Operating or storing the receiver outside the specified temperature range can damage it.

Regulations and safety

IEC 62368-1, IEC 60950-1, IEC 62311, IEEE C95.3, UN 38.3, UL 2054

Exposure to radio frequency radiation

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

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 the distance defined for each radio below.

  • 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.

  • DO NOT co-locate the antenna with any other transmitting device.

  • 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 licensed 450 MHz radio

Observe this precaution:

  • DO NOT operate the transmitter when someone is within the following distance of the antenna.

    • 410 to 470 MHz UHF radio – less than 26 cm (10.25 inches)

410 to 470 MHz radio (TR400900) is certified worldwide.

For license-free 900 MHz radio

Observe this precaution:

  • DO NOT operate the transmitter when someone is within the following distance of the antenna.

    • 902 to 928 MHz UHF radio - less than 40 cm (15.75 inches)

900 MHz radio (TR400900) is certified for Australia, Canada, and the USA.

For internal Wi-Fi and Bluetooth transmitters

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 further from the human body by a distance specified below. The internal wireless radio(s) operate within guidelines found in radio frequency safety standards and recommendations, which reflect the consensus of the scientific community. 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.

DO NOT operate the transmitter when someone is within the following distance of the antenna:

  • Bluetooth, Wi-Fi – less than 40 cm (15.75 inches)

For internal LTE or GSM/UMTS transmitters

Trimble receivers equipped with wireless cellular modem radios have been designed and manufactured to meet safety requirements for limiting exposure to radio waves. When used in accordance with the instructions set forth in this manual, the equipment has been independently verified to not exceed the emission limits for safe exposure to radio frequency (RF) energy as specified by the Federal Communications Commission of the U.S. Government in 47 CFR §2.1093. These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the general population. The guidelines are based on standards that were developed by independent scientific organization through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons, regardless of age and health.

DO NOT operate the transmitter when someone is within the following distance of the antenna:

  • LTE (4G) – less than 20 cm ( 7.9 inches).

    3G (GSM/UMTS) is already sunset.

Installing external UHF antennas

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 between yourself and the radiating antenna:

    • 410 to 470 MHz UHF radio - less than 26 cm (10.25 inches)

    • 902 to 928 MHz UHF radio - less than 40 cm (15.75 inches)

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

The GNSS receiver and its cabling should be installed in accordance with all national and local electrical codes, regulations, and practices. The receiver 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.

Trimble-approved antennas that can be used (country dependent) are:

  • The TR400900 (P/N 123130), Singular-Modular Transceiver (410 MHz to 470 MHz / 902 MHz to 928 MHz) was tested and certified per FCC Part 15.247 and Part 90 (FCC ID: S9E123130) for use with the antenna listed below:

    • A monopole antenna (P/N 129988) with peak gain of 1.85 dBi (410 MHz to 470 MHz) and 3.28 dBi (902 MHz to 928 MHz) and RP-SMA connector.

      or

    • A monopole antenna (P/N 24253-xx) with peak gain of 5.0 dBi (410 MHz to 470 MHz / 902 MHz to 928 MHz) and 5 m RG58 cable with RP-SMA connector (P/N 130626-05)

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.

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.

Contact your sales representative if you wish to review the type approval certificate for the receiver.

Battery safety

Trimble has included in the battery an internal authentication chip that has been tested and certified for safety.

  • Do NOT use any other battery. Only use Trimble battery (P/N 176767).

  • Charge and use the battery only in strict accordance with the instructions provided.
