Limited Lifetime Consumer Warranty
Directed Electronics, Inc. ("DEI®") promises to the original purchaser to repair or replace with a comparable reconditioned model any DEI unit (hereafter the "unit"), excluding without limitation the siren, the remote transmitters, the associated sensors and accessories, which proves to be defective in workmanship or material under reasonable use during the lifetime of the vehicle provided the following conditions are met: the unit was professionally installed and serviced by an authorized DEI dealer; the unit will be professionally reinstalled in the vehicle in which it was originally installed by an authorized DEI dealer; and the unit is returned to DEI, shipping prepaid with a legible copy of the bill of sale or other dated proof of purchase bearing the following information: consumer's name, telephone number and address; the authorized dealers name, telephone number and address; complete product description, including accessories; the year, make and model of the vehicle; vehicle license number and vehicle identification number. All components other than the unit, including without limitation the siren, the remote transmitters and the associated sensors and accessories, carry a one-year warranty from the date of purchase of the same. This warranty is non-transferable and is automatically void if: the original purchaser has not completed the warranty card and mailed it within ten (10) days of the date of purchase to the address listed on the card; the unit's date code or serial number is defaced, missing or altered; the unit has been modified or used in a manner contrary to its intended purpose; the unit has been damaged by accident, unreasonable use, neglect, improper service, installation or other causes not arising out of defects in materials or construction. [. . . ] In Valet Mode, all convenience functions (door locks, trunk release, etc. ) will remain operational. This feature is useful when washing or servicing your vehicle.

To enter or exit Valet Mode with the Valet switch: 1. The status LED will light steadily if you are entering Valet Mode and will turn off if you are exiting Valet Mode.
Remote Valet®
You can also activate Valet Mode with the remote transmitter: 1. again.
The status LED will light solid if you are entering Valet Mode and will turn off if you are exiting Valet Mode.
Nuisance Prevention® Circuitry
Your system has Nuisance Prevention® Circuitry (NPCTM) to prevent annoying repetitive trigger sequences caused by faulty door pin switches or environmental conditions such as thunder, jackhammers, airport noise, etc. Here's how it works: If the alarm is triggered by the same sensor or switch three times within a 60 minute period, your system interprets this pattern of triggers as false alarms. After the third trigger,

your system ignores, or bypasses, that sensor or switch (along with any other sensors or switches sharing the same zone) for 60 minutes. If the bypassed sensor is triggered again while it is already being bypassed, the 60-minute bypass period will start over. This ensures that a sensor that is continually being triggered will remain bypassed.
NOTE: Arming and disarming the system does not reset the Nuisance Prevention Circuitry. The only ways to reset a bypassed zone are for that zone not to be triggered for 60 minutes or to turn the ignition key on. When testing your system, it is important to remember that this circuitry can cause zones to be bypassed and appear to not work. If five chirps are heard when disarming the system, the NPC was engaged. To clear the memory, turn the ignition key on.
Diagnostics
The microprocessor at the heart of your system has the ability to constantly monitor all of the switches and sensors connected to it. It can detect any faulty switches or sensors and prevent them from disabling the entire system. It can also record and report any triggers that occur while you are away from your vehicle.
Arming Diagnostics
If the security system is armed at the same time that an input is active (door opening, sensor triggering, etc. ), you will hear one chirp to indicate arming and a second chirp to indicate Bypass Notification. A Bypass Notification chirp means that the system ignores the

input that was active when the system was armed, until that input ceases. Three seconds after that input ceases, the system will resume normal monitoring. For example, if your vehicle has an interior light exit delay and you arm the system before the light turns off, you may hear a second Bypass Notification chirp. Once the light turns off, however, the system resumes normal monitoring.
NOTE: Bypass Notification does not occur when the system is in Silent Mode or if the chirps have been programmed by the installer not to sound.
Disarming Diagnostics
Your system has a Tamper Alert feature that notifies you of system triggers that occur while you are away from your vehicle. If you hear four chirps when you disarm, this indicates that the system was triggered in your absence. If you hear five chirps when you disarm, this indicates that a specific zone was triggered so many times that the Nuisance Prevention Circuitry has bypassed that zone. In both cases, the pattern of the flashing status LED will indicate which zone was triggered (see Table of Zones). [. . . ] An input can be provided through a sensor, pinswitch or by existing systems in the vehicle, such as ignition or courtesy lights. LED: A red light mounted inside the vehicle, at a location determined by the installer. The LED indicates the status of your system and also reports triggers and faults in the system or sensors. Siren: A noise generating device, usually installed in the engine compartment of the vehicle. [. . . ]
