N:: Some European vehicles,
such as Mercedes-Benz and Audi, require longer lock and unlock
pulses to operate the vacuum pump. Programming the system to
provide 3.5 second pulses will accommodate door lock interface
in these vehicles. The default setting is 0.8 second door lock
pulses. See
Mercedes-Benz and Audi - 1985 and Newer (Type E
Door Locks section)
diagram.

N:: Some vehicles require
two pulses on a single wire to unlock the doors. When the
double pulse unlock feature is turned on, the H2/E
BLUE/BLACK wire will supply two negative pulses instead of a
single pulse. This makes it possible to directly interface with
double pulse vehicles without any extra parts.

F:: This system features Code
Hopping
™
as an option. Code Hopping
™
is a feature that uses a
mathematical formula to change the system’s code each time the
transmitter and receiver communicate. This makes the group of
bits or "word" from the transmitter very long. The longer the
word is, the easier it is to block its transmission to the unit.
Disabling the Code Hopping
™
feature lets the receiver ignore the
Code Hopping
™
part of the transmitted word. As a result, the
unit may have better range with Code Hopping
™
off.
