5.1. Main Box
The Vigil
®
Cuatro electromagnetic shield was thoroughly tested to ensure that it would function as intended when
exposed to electromagnetic interference (up to 100 volt/m).
Such interference can be found in airports and aircraft.
The special shielding foil protects against electromagnetic interference waves produced by:
• Radio communications • Mobile phones
• Transponders • Radar
Two connectors and three integrated stainless steel filters are fixed in the Main-Box.
The stainless steel filter ensures protection against pollution, such as the intrusion of dust, and provides a instant
transfer of outside air pressure to the pressure sensor (keep it clean and dry).

5.2. Dual Battery Pack
The battery pack is composed of 2 metal lithium AA cells in the lower half of the case. It is not subject to any memory
effect and is extremely long lasting. The battery pack works at a temperature range from -13°F to +158°F or from -25°C to
+70°C. The use of low consumption components in conjunction with a sophisticated power management program has
significantly improved the battery’s life span. The battery’s life span is expected to be a minimum of 5 years, or 2000
jumps. When the « Bat Low » or « Bat Rpl » message appears, the battery pack needs to be replaced (see page 31 § 7.1).
Regardless of the above-stated life span, the battery pack must be replaced after 10 years of
use (max. operational lifetime).
To replace the battery, the complete Vigil
