Evidence of at least six separate systems in one or more of the above categories is required. c Candidates are expected to perform the elements of this unit standard without direct technical supervision, and with complete responsibility for quality and quantity of output. This may include responsibility for the output of others. d All work assessed against this unit standard must comply with the requirements of the Health and Safety at Work Act 2015, relevant regulations, and applicable site and company occupational safety and health procedures. e The installer is to be supplied with design specifications and/or detailed instructions regarding the installation. Installation excludes system design or layout, contract negotiations, or commissioning and operational configuration adjustments required in complex network installations. Outcomes and performance criteria Outcome 1 Plan and prepare for the installation of telecommunications radio frequency systems. 1.1 Evaluation of job contract, job specification, time-lines, and discussion with customer establish the scope and timing of the installation work. 1.2 Installation plan is developed in terms of available resources, required materials, timing, relevant authorities, and site access, and details are agreed with customer. 1.3 All site occupational safety and health implications for self and others are identified, and hazard control measures put in place.

Outcome 2 Install telecommunications radio frequency systems. 2.1 The fitting, mounting, location, and positioning of hardware is in accordance with specifications and industry practice. Range typical hardware cable trays, ducting, terminating blocks, cabinets, frames, connectors, feeders, antennae. 2.2 Cabling or feeders are installed in accordance with specifications and industry practice. 2.3 Radio or cellular equipment is positioned, terminated and designated in accordance with specifications and industry practice. 2.4 Documentation of installation progress is maintained in accordance with company requirements. 2.5 Drawings are marked up to reflect the as-built situation. 2.6 Sites are restored to customer expectations following completion of installation. Outcome 3 Acceptance test telecommunications radio frequency systems. 3.1 Visual inspection confirms that all specified items have been installed as per specifications. 3.2 Testing confirms that cabling and feeder interconnections are to the specified terminations. 3.3 Acceptance tests for the radio or cellular system, including antennae alignment where appropriate, are completed in accordance with specification and industry practice, and any discrepancies resolved. 3.4 Test results are recorded in accordance with specifications and customer and/or company requirements.

4 Page 4 of 5 Outcome 4 Hand-over telecommunications radio frequency systems to customer. 4.1 The radio frequency systems are made available to the customer by the agreed date, and, in cases where it impacts upon a network or larger system, plans for the commissioning are agreed with the customer. 4.2 Customer is advised of demarcation points, and issues and options regarding ownership and maintenance of the system. 4.3 Support materials are supplied to customers at hand-over in accordance with contract and company requirements. Range typical support materials as-built drawings, performance certification, test results, maintenance materials, product leaflets and instructions, testing instructions, troubleshooting guides. 4.4 Hand-over documentation is completed in the agreed format, in accordance with customer and company requirements. Outcome 5 Fault-find and repair telecommunications radio frequency systems. 5.1 Observations and measurements are interpreted logically, and lead to the location of radio path fault, or faulty system elements, or components. 5.2 Faulty elements or components are repaired to industry standards or replaced with same or equivalent items. 5.3 Testing confirms restoration to full service. 5.4 Sites are restored to customer expectations following completion of repair work. 5.5 Customer is advised of restoration of service, and records are completed in accordance with customer and company requirements. Outcome 6 Retrofit an existing telecommunications radio system installation. 6.1 Project documentation, site survey, and/or discussions with customer or project engineer are used to establish the scope of the retrofit.
