7.1 The recording and processing device should be of robust, tamper-proof design with
read-only capability.
7.2 The recording and processing device should record the data required by
sections 4.4.7, 5.4.2, and 10.3 against UTC and ships position by a Global Navigational
Satellite System (GNSS).
7.3 The recording and processing device should be capable of preparing
reports over specified time periods.
7.4 Data should be retained for a period of not less than 18 months from the
date of recording. If the unit is changed over that period, the shipowner should ensure
that the required data is retained on board and available as required.
7.5 The device should be capable of downloading a copy of the recorded data
and reports in a readily useable format. Such copy of the data and reports should be
available to the Administration or port State authority as requested.
