Thank you for trusting Prestige products! If you are a consumer, please note:
Professional installation is strongly recommended.
This manual assumes the installer has adequate knowledge of the following expertise. Therefore, it does not
cover these topics in detail:
• 12-volt electronics
• Testing and verifying circuits
• Making safe and lasting wiring connections
• Factory ignition, power, lighting, data bus and sensing systems
• Factory systems and components to avoid
• Safe wire routing, circuit protection and product placement
• Access to vehicle-specific technical information
In addition, this manual assumes the installer has the proper tools, skill and facilities to perform a professional installation.
Performing an improper installation could result in damage to the vehicle or its components, improper system function,
unsafe vehicle operation or physical injury. Such instances would not be covered by the vehicle manufacturer's warranty,
nor by Voxx Electronics, Inc.

Detailed Descriptions: External Components & Operation
Shock Sensor
This system includes an on-board shock sensor. The main module should be securely mounted to a vehicle surface or
sturdy wire harness. Testing takes place after all connections are made and the system is powered up. An external shock
sensor can be added for additional protection. The external shock sensor will connect to the 4-Pin shock sensor port on
the module.
LED / Valet Programming Port
The LED / Valet Programming port is used to for Valet Override.
1. Find a suitable location to mount the supplied LED / Valet Programming button. Locate a clear spot on the vehicle’s
dashboard that will be seen from the outside of the vehicle.
2. Drill a 5/16 inch hole and mount the LED / Valet button. Route the wires to module and plug into proper location.
The Valet Override procedure will disable the alarm when the remote is not available or has become inoperative. If the
vehicle door is opened without disarming, the alarm will sound and the vehicle will not start when attempting to start
with the key. To disable the alarm:
1. Turn the vehicle ignition to ON.
2. Within five (5) seconds, press and hold the valet button on for one (1) second.
The alarm will silence and the vehicle will now start normally with the key.
Valet Alarm Override
Adjusting the Shock Sensor
1. Arm the system, wait 5-10 seconds, then with an open palm carefully apply impact to areas of the vehicle to test the
shock sensor’s sensitivity.
2. To adjust, turn the adjustment knob on the shock sensor counter-clockwise for less sensitivity; clockwise for more
sensitivity.
3. If the proper sensitivity still cannot be achieved, re-locate the shock sensor.
