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 Module
(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
which is programmed to recognize the digital code
of the safety lanyard cap. This is achieved with the
VCK (P/N 529 035 676) or with the MPEM pro-
grammer (P/N 529 034 500). Refer to
Guide to pro-
gram a safety lanyard.
The system is quite flexible. Up to eight safety lan-
yards 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.
The memory of the MPEM has also two self-
diagnostic modes.
When ordering a new MPEM from the regular
parts channel, the DESS circuitry will be activated.
