TRB245 Safety Information
This device meets the government’s requirements for exposure to radio waves. This device is designed and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the authorized agencies. To ensure compliance with RF exposure guidelines the device must be used with a minimum separation of 20 cm from a person's body. Failure to observe these instructions could result in your RF exposure exceeding the relevant guideline limits.
External antennas used with TRB245 must be installed to provide a separating distance of at least 20 cm from all persons and must not be co-located or operated in conjunction with any other antenna or transmitter.
Any external antenna gain must meet RF exposure and maximum radiated output power limits of the applicable rule section.
|Antenna type||Frequency range||Impedance||VSWR||Gain*||Radiation||Connector|
|Mobile||800~960 MHz, 1710~2690 MHz||50 Ω||≤ 3.0||≤ 4 dBi||omnidirectional||SMA male|
|GNSS||1575.42~1602 MHz||-||2.0 max||28 dB + 1.5/-3 dB||RHCP polarization||SMA male|
*Higher gain antenna can be connected to compensate for cable attenuation when a cable is used. The user is responsible for the compliance with the legal regulations.
|Maximum transmission power|
- Operating temperature: -40° to +75° Celsius
- Humidity should be in the range of 10% to 90% (non-condensing). Only use the device in dry environments.
- Out of direct sunlight
- Away from heat source
- Away from corrosive substances, salts and flammable gases
Attention: operation outside the permissible range can considerably shorten the service life of the device.
