Maintenance
Regular maintenance ensures the longevity and optimal performance of your Viper security system.
Remote Control Battery Replacement:
The 4-button remote controls are powered by 2 AAA batteries. When the remote's range decreases significantly or the LED indicator on the remote becomes dim, it's time to replace the batteries.
- Locate the battery compartment on the back of the remote control.
- Open the compartment cover.
- Remove the old AAA batteries.
- Insert two new AAA batteries, ensuring correct polarity (+ and -).
- Close the battery compartment cover securely.
Shock Sensor Sensitivity Adjustment:
The Stinger® DoubleGuard® Shock Sensor's sensitivity can be adjusted to prevent false alarms or to ensure adequate detection. This adjustment is typically done via a dial or button on the sensor unit itself. Consult your installer or the detailed product manual for the exact procedure.
General Care:
- Keep remote controls dry and away from extreme temperatures.
- Periodically check wiring connections for security, especially after vehicle maintenance.
- Clean the exterior of the components with a soft, damp cloth. Do not use harsh chemicals.
