menu #1 - basic features

1-1 ACTIVE/PASSIVE ARMING: When active arming is selected, the system will only arm when the remote
control is used. When set to passive, the system will arm automatically 30 seconds after the last door is
closed. To alert the consumer of passive arming, the siren will chirp 20 seconds after the door is closed.
This provides the consumer with an audible warning prior to the system actually arming. At the 30 second
mark, the system will arm, but the siren will not chirp.
1-2 CHIRPS ON/OFF: This feature controls the chirps that confirm the arming and disarming of the
system.
1-3 IGNITION LOCK ON/OFF: When turned on, the doors will lock three seconds after the ignition is turned
on, except when a door is open.
1-4 IGNITION UNLOCK ON/OFF: When ON this feature will unlock the doors when the ignition is turned
off.
1-5 ACTIVE/PASSIVE LOCKING: If passive arming is selected in Feature 1-1, then the system can be
programmed to either lock the doors when passive arming occurs, or only lock the doors when the system
is armed via the remote control. Active locking means the system will not lock the doors when it passively
arms. Passive locking means that the system will lock the doors when it passively arms.
1-6 PANIC WITH IGNITION ON: This feature controls whether or not the panic mode is available with the
ignition ON. In some states, there are laws prohibiting a siren sounding in a moving vehicle. This feature
makes the system compliant with these regulations.
1-7 DOOR LOCK PULSE DURATION: 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 the door lock interface in these vehicles. The default setting is 0.8 second door
lock pulses. Some modification to the door lock harness (H2) is also necessary. (Refer to TechTip 1041
for wiring information regarding (+/-) Door Lock Outputs Harness (H4)section, Type E - Mercedes-Benz
and Audi -1985 and Newer" diagram.) The 0.4 second pulse is required on some of the newer Chrysler and
