How do I Troubleshoot a Karr Security System Model 2040A?by Quinten Plummer
The Karr 2040A is an automotive alarm system. The 2040A employs a variety of security measures to keep your car safe from theft. When the device's shock sensor is jarred, the 2040A flashes your vehicle's parking light, honks the horn and sounds its own siren. The 2040A can also disable your automobile's starter. If you encounter problems with your 2040A, complete basic troubleshooting to correct the problems.
Adjust the sensitivity of your Karr 2040A, if your security system experiences frequent false alarms. Locate the 2040A's shock box, which is usually found under the steering column. Using a Phillips screwdriver, turn the shock box's screw counterclockwise to lower the system's sensitivity.
Ensure that your automobile's doors, hood and trunk are closed if you experience problems arming your 2040A. The system will not arm until all of these components have been completely closed. The automobile's engine must also be off.
Check the battery LED on your 2040A's remote control, if you notice a decrease in the remote control's range. If the LED is weak or not visible, replace the battery in the remote control.
Use a Phillips head screwdriver to remove the screws from the bottom of the remote control. Remove the top half of the remote control from the bottom. Replace the old battery with a fresh GP 23A 12 battery, and then reconnect the remote control's cover and replace the screws.
