Introduction - AAD Vigil Cuatro User Manual

2. Introduction

Your Vigil Cuatro was designed and developed by a professional team of engineers and skydivers.
®
Its function is to cut the reserve closing loop in the event that you reach a freefall speed at an
unsafe altitude. The flat aluminum alloy box is exceptionally strong; its ergonomic design fits easily into most
current rigs.
A Vigil Cuatro installation kit (pouch, controller window and cutter retainer) can be supplied to rig
®
manufacturers, on demand. The Vigil Cuatro can be used for four types of skydiving by pushing just
®
one button. These user programmable modes are: «PRO», «STUDENT», «TANDEM» or «XTREME».
The Vigil Cuatro also has a data recorder function (black box). The unit memorizes the last 16 minutes of freefall
®
time (with a maximum of 16 graphs, whichever is reached first), total time in freefall and total number of jumps.
This data can be viewed directly from the control unit's LCD display, or it can be downloaded to a PC through an
infrared communication port.

The infrared reader and the associated software are available as an option (see page 38 § 9).
The Kevlar reinforced cables are especially developed for the Vigil .Cuatro and deliver a unique combination of
®
strength and flexibility.
The gold plated contacts and the locking system with a special locking clip on the connectors ensure optimal
connection reliability in all circumstances.
The control unit:
- is equipped with a 32 x 96 dots LCD display which allows interactive and clear
communication with the parachutist.
- is protected by a special anti-scratch coating and a stainless steel protection cover.
The electromagnetic shielding protects the Vigil Cuatro from electromagnetic interferences, such as those found
®
in airports and airplanes (see page 27 § 5.1).
