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 TDL450B radio is a high-precision electronic instrument and should be treated with reasonable care.

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

The radio is designed to comply with the following national and international standards and guidelines regarding exposure of human beings to radio frequency electromagnetic energy, in addition to protection against harmful interference of neighboring electrical equipment.

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.

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.

Installing antennas

RF Exposure! To comply with RF exposure compliance requirements in Europe, USA, and Canada, the maximum antenna gain is 14 dBi and a separation distance listed below must be maintained between the antenna of this device and all persons. This device must not be co-located or operate in conjunction with any other antenna or transmitter.

To ensure optimal radio performance and that exposure to RF energy is within the guidelines on the above standards, observe the following operating procedures:

  • Do not operate the transceiver unless all RF connectors are secure and any open connectors are properly terminated.

  • Avoid contact with the antenna while operating the transceiver.

  • Do not operate the transceiver with a damaged antenna. If a damaged antenna comes in contact with the skin, a minor burn may result.

  • Do not operate the equipment near electrical blasting caps or in an explosive atmosphere.

  • Antennas are excellent conductors of electricity, so use extreme caution when operating near power lines and other sources of electrical current or during stormy weather. If an antenna is installed in a location exposed to lightning, Trimble recommends inserting a lightning surge protector in between the antenna and the radio.

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.

Exposure to hot surfaces

The TDL450B enclosure and heat sink may become very hot during operation, depending on the air temperature, transmit power, and transmission duty cycle. Turn off the unit and let it cool before handling. Always use the heat resistant handle to hold or move the TDL450B radio.

Touching the heat sink with your skin may result in light burns when the TDL450B radio is working in high air temperature or low ventilation with transmission power and duty cycle at set high levels.

Rechargeable batteries

The TDL450B radio requires a 9 V to 30 V power source to function. To operate the radio at a higher than 5 W transmission power, you need an input voltage higher than 11 V. Trimble recommends using 12 V deep discharge or 12 V LiFe Po batteries. The battery capacity you need depends on the transmission power setting and duty cycle you are using. A 35 Ah battery should last you at least eight hours of operation. Please refer to the battery manufacturer for usage, charging, and storage recommendations.

Storing batteries for an extended period of time in a discharged status will damage them. Please refer to the documentation included with your battery.

Trimble offers fused battery cables for your convenience. For specific safety information, please refer to the documentation included with your battery.

Power

The TDL450B radio must be powered by a fused power source capable of delivering 200 W with voltage between 11 V and 30 V. Always use Trimble P/N 130919 power cable to power the radio.

Wet locations

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