Before the equipment is switched on for the first time after installation or after renewals or extensions of the ship's survey certificate (except according to Article 2.09(2) of Annex II) as well as after each modification of the vessel likely to affect the operating conditions of the equipment, an installation and performance test shall be carried out by the competent authority or by a firm authorised in accordance with Article 3. For this purpose, the following conditions shall be fulfilled:
the power supply shall have a separate safety device;
the operating voltage shall be within the tolerance (Article 2.01 of Part III);
the cabling and its installation shall satisfy the provisions of Annex II and, if necessary, the ADNR;
the number of antenna revolutions shall reach at least 24 per minute;
there shall be no obstruction in the vicinity of the antenna which impairs navigation;
the safety switch of the antenna shall be in good working order;
the arrangement of display units, rate-of-turn indicators and control units shall be ergonomic and user-friendly;
the lubber line of the radar equipment shall not deviate from the ship's fore-and-aft-line by more than 1 degree;
the accuracy of the range and azimuthal displays shall satisfy the requirements (measurements using known targets);
linearity in short ranges shall be correct (pushing and pulling);
the displayed minimum range shall be 15 metres or less;
the centre of the picture shall be visible and its diameter shall not exceed 1 mm;
False echoes caused by reflections and unwanted shadows on the lubber line shall not occur or shall not impair the safety of navigation;
Sea-clutter and rain-clutter suppressors (STC and FTC preset) and the associated controls shall perform correctly;
the gain adjustment shall be in proper working order;
focus and picture definition shall be correct;
the ship's turning direction shall be as indicated on the rate-of-turn indicator and the zero position at dead ahead shall be correct;
the radar equipment shall not be sensitive to transmissions by the ship's radio equipment or to interference from other on-board sources;
the radar equipment and/or rate-of-turn indicator shall not interfere with other on-board equipment.
Furthermore, in the case of inland ECDIS equipment:
the statistical positional error affecting the chart shall not exceed 2 m;
the statistical phase angle error affecting the chart shall not exceed 1 degree.
