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 TDL510 radio is a high-precision electronic instrument and should be treated with reasonable care.

CAUTION – Operating or storing the radio outside the specified temperature range can damage it.Storage temperature range -40 °C to +85 °C (-40 °F to 185 °F) in a dry environment.

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 and KDB447498, RF Exposure Procedures and Equipment Authorization Policies For Mobile and Portable Devices. Proper use of this radio results in exposure below government limits.

The following precautions are recommended:

  • 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.

CAUTION – For your own safety, and in terms of the RF exposure requirements of the FCC, always observe these precautions:

  • For the 450 MHz radio, always maintain a minimum separation distance of 45 cm (17.7 inches) between yourself and the radiating antenna.

  • The 450 MHz radio is using 4FSK and GMSK modulations.

  • 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:

  • For the 900 MHz radio, always maintain a minimum separation distance of 20 cm (7.8 inches) between yourself and the radiating antenna.

  • The 900 MHz radio is using BPSK modulation.

  • All equipment should be serviced only by a qualified technician.

NOTE – The 900 MHz radio is certified for use in the USA and Canada.

Installing antennas

CAUTION – For your own safety, and in terms of the RF exposure requirements of the FCC, always observe these precautions:

  • For the 450 MHz radio, always maintain a minimum separation distance of 45 cm (17.7 inches) between yourself and the radiating antenna.

  • For the 900 MHz radio, always maintain a minimum separation distance of 20 cm (7.8 inches) between yourself and the radiating antenna.

WARNING – The radio and its cabling should be installed in accordance with all national and local electrical codes, regulations, and practices. The radio 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.

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.

Lightening protection of fixed antennas

Trimble recommends using a lightning surge protection equipment on all fixed antennas. This device will reduce the risk of electrical shock to the radio that could occur if lightning struck the antenna, the antenna mast, or an object close to the antenna. When installing a fixed antenna on a metallic mast, Trimble recommends installing the antenna on the mast side, not too close to the mast, so that the top of the mast protects the antenna from a lightning strike. The mast must be properly grounded on the lower end as per applicable local regulatory standards for lightning strike protection.

Trimble recommends lightning surge protector devices that cover at least the 403 MHz to 470 MHz frequency range and allow a maximum transmission power greater than 1 W. The device installation must follow the supplier’s recommendations.

Trimble products damaged by a lightning strike will not be covered by a warranty repair.

Wet locations

WARNING – This product is not intended to be used outdoors or in a wet location when it is powered by the external AC power supply. The connection is not waterproof and could be subject to electrical shorting.

WARNING – The external power adapter and its associated power cord and plug are not intended to be installed outdoors, or in a wet location.
