It contains the general guidelines for the field engineers /technicians. Read carefully before starting the DB-5R-30 repeater installation. 2.0 Important Safety Information The DB-5R-30 repeater has been designed for maximum safety when installed and operated according to the instructions in this manual. Refer to all safety instructions as per the antenna installation instruction sheets. Do not bypass any of the safety features with the equipment provided, nor operate the system in an inappropriate environment. 3 WARNING! Installation of antennas near power lines is dangerous. For your safety, follow all installation directions and keep safe distance from any high voltage power lines that could result in shock or loss of life. 4 Antenna – Electronic Communication Systems WARNING! This equipment complies with FCC & IC radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be co- located or operating in conjunction with any other antenna or transmitter. For mobile or fixed location transmitters, the minimum separation distance is greater than 40 cm, even if calculations indicate that the MPE distance would be less. Additional wiring required to install the DB-5R-30 system should comply with national or local governing Electrical Codes. Indoor RF coaxial cable installations should comply with local Electrical Code requirements. The DB-5R-30 repeater should only be installed in restricted access areas such as dedicated equipment rooms or closets. The DB-5R-30 repeater is designed for indoor application; the housing is not waterproof. So please keep it away from water, rain and any chemical liquid. Do discharge the static before you touch the connectors of the repeater. Do not open the module inside the repeater unless you are authorized. The power supply unit in the…
