Latwne S830 LCD Display Screen User Manual

Introduction

The Latwne S830 LCD Display Screen is a versatile and essential component for electric bicycles (ebikes), designed to provide comprehensive information and control over your ebike system. This universal meter panel is compatible with 24V, 36V, and 48V ebike setups and features a convenient USB port for charging or data transfer. It functions as a driving computer, displaying critical data such as remaining battery, current speed, average speed, maximum speed, clock, and trip distance. When a Pedal Assist System (PAS) is installed, the S830 LCD allows the rider to select the desired auxiliary level, enhancing the riding experience.

This manual provides detailed instructions for the installation, operation, maintenance, and troubleshooting of your S830 LCD Display Screen to ensure optimal performance and longevity.
