MANAGEMENT section.
GENERAL
The Digitally Encoded Security System (DESS)
features an anti-start protection against unautho-
rized use of the watercraft.
The following components are specially designed
for this system: Multi-Purpose Electronic Mod-
ule (MPEM), safety lanyard cap and safety lanyard
switch.
The safety lanyard cap has a magnet and a ROM
chip. The chip has a unique digital code.
The DESS circuitry in the watercraft MPEM is ac-
tivated at the factory. Therefore, a safety lanyard
must be programmed to start the engine.
NOTE: Actually, it is the memory of the MPEM
whichisprogrammedtorecognizethedigitalcode
of the safety lanyard cap.
The system is quite flexible. Up to eight safety
lanyards may be programmed in the memory of
the watercraft MPEM. They can also be erased.
NOTE: If desired, a safety lanyard can be used on
other watercraft equipped with the DESS.
The memory of the MPEM is permanent. If the
battery is disconnected, no information is lost.
When ordering a new MPEM from the regular
parts channel, the DESS circuitry will be activat-
ed.
The MPEM features a self-diagnostic mode. Re-
