This element has an operational lifetime of 20 years and under normal circumstances it will never need replacement.

5.4. Electronic Unit

The entirely automated assembly of surface-mounted electronic components (SMD, Surface Mounted Devices) is
manufactured to the highest standards. The SMD components assemblies are assembled with permanent electronic
and optical production control equipment in order to ensure the highest level of quality and reliability, equivalent to
28
military standards. The electronic unit also works as a data recorder. It memorizes parameters (see page 19 § 3.5.6)
such as the total number of jumps, the duration of the last freefall jump and the total freefall time. This data can be
viewed directly on the control unit's LCD display.
The Vigil Cuatro memory contains the graphs of the last 16 minutes of freefall and partial canopy ride, and
®
can be downloaded to a PC using the Vigil Cuatro communication port. (see page 38 § 9.)
