Setup and Installation
The Viper Responder 350 2-Way Security System requires professional installation. This section provides a general overview of the components and their typical placement. For detailed wiring diagrams and vehicle-specific instructions, consult a certified Viper installer.
Control Module Placement
The main control module (brain unit) should be securely mounted inside the vehicle's cabin, typically under the dashboard, away from direct moisture and excessive heat. Ensure it is not easily accessible to unauthorized individuals.
Siren Installation
Mount the siren in the engine compartment, facing downwards to prevent water accumulation. Choose a location that is difficult to access from outside the vehicle and away from moving parts or extreme heat.
Shock Sensor Adjustment
The shock sensor detects impacts to the vehicle. It should be mounted securely to a solid surface within the vehicle's interior. The sensitivity can be adjusted to prevent false alarms while ensuring adequate protection. Refer to the installer's guide for specific adjustment procedures.
Remote Control Battery Installation
The 2-Way LCD Remote Control requires 2 AAA batteries.

Operating Instructions
This section details the basic functions of your Viper Responder 350 security system using the remote controls.
Arming the System
To arm the security system and lock your vehicle's doors, press the Lock button on your remote control. The siren will chirp once, and the parking lights will flash once. The 2-way remote will confirm the armed status.
Disarming the System
To disarm the security system and unlock your vehicle's doors, press the Unlock button on your remote control. The siren will chirp twice, and the parking lights will flash twice. The 2-way remote will confirm the disarmed status.
Silent Arming/Disarming
To arm or disarm the system silently, press the Lock or Unlock button followed immediately by the Function button (often labeled with a speaker or mute icon). The system will arm/disarm without siren chirps.
Trunk Release
To open your vehicle's trunk (if connected), press and hold the Trunk Release button (often labeled with a trunk icon) for approximately 3 seconds.
Panic Mode
To activate the panic alarm, press and hold the Panic button (often labeled with a siren icon) for 3 seconds. The siren will sound, and the parking lights will flash. To deactivate, press any button on the remote.
Valet Mode
Valet mode temporarily bypasses the security features of the system, allowing your vehicle to be serviced without triggering the alarm.
- Turn the ignition key to the ON position.
- Within 10 seconds, press and release the Valet switch. The LED will turn on solid.
- To exit Valet mode, repeat steps 1 and 2. The LED will turn off.
Maintenance
Remote Control Battery Replacement
When the 2-way LCD remote's battery indicator shows low power, replace the two AAA batteries. For the 1-way remote, replace the CR2032 coin cell battery when the range decreases significantly or the LED indicator dims.
System Cleaning
Keep the control module and sensors free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners directly on electronic components.
Regular Checks
Periodically test the system's functions, including arming, disarming, shock sensor, and siren, to ensure proper operation.
