JTC-1719A Auto Computer Memory Unit

1. Key Features

The JTC-1719A Auto Computer Memory Unit is designed to maintain continuous power to sensitive vehicle electronics during battery replacements. It operates seamlessly by connecting a standard 9V battery and plugging directly into the vehicle's cigarette lighter socket. This unit effectively preserves radio presets, digital clock settings, anti-theft security codes, and vital engine control unit (ECU) memory settings for up to 4 hours while the main battery is disconnected.

 

2. Practical Applications

The JTC-1719A is an essential tool for auto repair shops, battery service technicians, and DIY mechanics. It is utilized whenever replacing a vehicle battery or performing electrical maintenance that requires disconnecting the main power supply. By keeping the vehicle's onboard memory intact, it prevents driveability issues caused by cleared ECU parameters, avoids locked radio units, and eliminates the hassle of re-configuring user preferences.

 

3. How to Use

Before disconnecting the vehicle's main battery, insert a fresh 9V battery into the JTC-1719A unit. Insert the adapter plug into the vehicle's cigarette lighter socket and turn the ignition switch to the ACC position if required to energize the socket. Once the backup supply is established, safely disconnect and replace the main car battery. After installing the new battery, remove the JTC-1719A plug from the socket.

 

4. Device Maintenance

Always remove the 9V battery from the JTC-1719A after each use to prevent battery depletion and corrosive leakage. Keep the unit clean by wiping it with a dry, soft cloth, ensuring the plug contacts remain free from dirt and grease. Store the device in a cool, dry place away from direct heat or moisture. Periodically inspect the battery terminals and lighter plug connectors to ensure reliable conductivity for future operations.
