Equipment: Installation companies working on these types of installations must have, at a minimum, the appropriate measurement range and precision equipment that incorporates the measurement functionalities included in the following devices: multimeter, earth tester, insulation tester, field strength meter with display and the ability to perform spectral analysis and error rate measurements on QPSK and COFDM digital signals, intermediate frequency simulator (5-2150 MHz), selective optical power meter and single-mode optical fiber tester for FTTH, equipment for splicing or connectorization in the field for single-mode optical fiber and analyzer/certifier for category 6 or higher telecommunications networks.

Obligations of the telecommunications installation company.
Each telecommunications installation company shall have the following obligations:

1. To execute, modify, expand, maintain or repair the telecommunications installations entrusted to them, in accordance with current regulations and with the content and instructions of the applicable technical project where it exists, using, where appropriate, materials and equipment that comply with the legislation applicable to them.

2. Carry out the review and maintenance operations of the telecommunications facilities entrusted to them in the manner and timeframes provided. 

3. Comply with the applicable legal provisions regarding the protection and information of consumers and users.

4. Maintain the requirements that gave rise to the validity of your responsible declaration as a telecommunications installation company, and communicate to the State Secretariat for Telecommunications and the Information Society, by electronic means, using the standardized model included in Annex II of this order, any modification of the same within a maximum period of one month from the moment it occurs, in accordance with the provisions of Article 3.4 of the Regulation governing the activity of installation and maintenance of telecommunications equipment and systems.

5. Complete and sign the corresponding installation certificate, the standardized model of which is included as Annex III to this order, test protocol, if applicable, and accompanying documentation, delivering it to the owner of the property, or their legal representative, and in cases where current legislation so determines, to the competent administration.

6. To assist and collaborate with the inspections carried out by the State Secretariat for Telecommunications and the Information Society when required to do so.

Documentation relating to the last calibration performed on the measuring equipment, as well as documentation relating to all verifications carried out since the last calibration, must be kept on file. A maximum period of one year is established between two successive verifications. If the result of these verifications establishes that the equipment is out of specification, it will be mandatory to have it calibrated at an authorized center. Furthermore, the documentation and operating manuals for the aforementioned measuring equipment must be maintained. The equipment to be calibrated and its calibration frequency will be established by an Instruction from the Director General of Telecommunications, approved by a resolution to be published in the Official State Gazette.

8. Keep, during the warranty and maintenance period agreed for the installation, the documentation and installation and maintenance manuals of the equipment and materials used in carrying them out, as well as deliver to the owner of the property, or his legal representative, the relevant instructions for use of the installations carried out.

9. Have up-to-date documentation that includes the legal texts applicable to the activity they carry out.
