You close the safe door and punch in any 4 digit codes and then “lock” button. This will cause the entered 4 digit code to be saved and door to be locked. - To open the safe, either you enter master preprogramed code or the code you entered before hitting the lock button. - Once locked, a red led will turn on to indicate locked status. If unlocked, a green led will turn on to indicate unlocked status. - If wrong code entered three consecutive times then a siren will sound. - Implement a timer to turn off the LEDs after X seconds to save power.

AvantGuard 4’s BlackJax feature provides a safe and effective means of recovering your vehicle after a theft or carjacking. In a carjacking situation, the sooner you are out of the car the better. Don’t resist or take anything with you, just get out and get away. The instant the car door is opened, your AvantGuard 4 takes charge. First it allows the carjacker to drive a short distance, ensuring your safety. Then it repeatedly flashes the brake lights and continuously sounds the siren to caution nearby drivers and draw attention to your stolen vehicle. The system ignores the remote control at this point (since the carjacker most likely has it). Then when the carjacker slows for a turn or traffic, BlackJax safely shuts down the engine and prevents it from being restarted. AvantGuard 4 assures the thief cannot restart the engine even if he were to find and remove the system control unit. Unable to restart the engine, and with your vehicle stalled in the middle of traffic — siren wailing and lights flashing — the carjacker has no choice but to abandon your car. (The same occurs to anyone who steals your parked car from you at a gas station or in a parking lot, which are the most common carjacking sites). To recover your vehicle, you simply walk a block or two to your car, enter your PIN (personal identification number) code, and the system releases control of the vehicle to you. Your secret PIN code tells the system that the car is being driven by an authorized person. If you or a passenger opens and closes a car door at any point while the engine is running (as would occur in a carjacking attempt), you must again enter your secret code.: Five seconds after you exit, close all the doors and the interior light has turned off, the indicator lights flash twice to confirm the AutoArming countdown is progressing. Then, 25 seconds later, the system will AutoArmYour system’s other sensor, the Digital Dual-Zone Proximity Sensor 4, detects movement inside the passenger compartment and very near your vehicle. If a thief lingers very close to your windows, a warning tone sounds; if he were to lean into the passenger compartment, the primary zone of this sensor would trigger the full alarm. This sensor uses radar waves to detect movement. These waves pass through nonmetallic materials like plastic, carpet, glass and wood. However, metal and metallic paint, plastic and even some metallic film window tinting materials will interfere with or completely block the radar waves. As such, it is not unusual that the Proximity Sensor zones may need a little readjustment when you first have the system installed. In some instances, your Clifford installer may need to try a different location for the sensor.
