This document outlines the procedure for replacing the backup battery in a Garmin® GPS-III+ device. The primary function of this guide is to provide detailed instructions for users encountering a "backup battery has lost charge" screen message, indicating the need for a battery replacement.
The Garmin® GPS-III+ is a GPS device that utilizes a backup battery to retain stored information such as waypoints. When this battery loses charge, the device prompts the user to replace it. The replacement process, as described, involves intricate steps of disassembling the device, desoldering the old battery, and soldering a new one. It's crucial to note that removing the backup battery will result in the deletion of all waypoints and other stored information, implying that the backup battery's primary function is data retention during power loss or main battery changes.
Overall, this document serves as a comprehensive maintenance manual for a specific, somewhat advanced, repair on the Garmin® GPS-III+ device, emphasizing the necessary tools, skills, and careful execution required.
