Introduction

Congratulations on your purchase of the VONSET L6—your always-ready chess partner for play, practice, and improvement.

The L6 combines a sensor chessboard, circular LED move guidance, adaptive computer play, and an E-ink screen. The board detects the pieces directly, so you can focus on the position instead of repeatedly looking at a separate display.

Start Playing Chess

Begin a game

Fully charge the battery before first use. Press ON/OFF to start the L6. During startup, the device beeps, the LEDs illuminate, and the pieces are detected. Place all pieces in the standard starting position and make the first move.

By default, the player uses White and L6 uses Black. You do not need to press the squares; move the pieces naturally.

LED move guidance

When L6 makes a move, the starting and destination squares flash alternately. Move the indicated piece for L6; the lights stop and it becomes your turn.

Castling and pawn promotion

Short castling is shown as 0-0 and long castling as 0-0-0. Move the King first, then the Rook.

When a pawn reaches the opposite side, use Up and Down to select a promotion piece and press OK to confirm. If no piece is selected, L6 assumes promotion to a Queen.

Ending and resuming a game

The display reports checkmate, stalemate, or draw. A win is shown as 1-0 or 0-1, and a draw as ½-½. To start a new game, return all pieces to the starting position. To adjourn a game, power the L6 off normally; after restart, replace the pieces as shown on the display and continue.

Chapter 5

Game Mode

Select a mode with Up or Down, confirm with OK, and return with Back. Changing mode during a game begins a new game.

Score

L6 evaluates each move and provides a game score. The evaluation considers material, piece activity, pawn structure, and tactical possibilities—not material count alone.

Chapter 6

Game Time

The game timer is off by default. Open the menu, choose Game time, select a time, and confirm with OK. Available times are 2, 5, 10, 20, 30, 45, 60, or 90 minutes per player.

The player's clock starts after the first move. L6's clock counts down while the computer thinks; the player's clock resumes after the indicated computer move is made on the board. A game may continue even if a clock reaches 0:00:00.

Chapter 7

Level Setting

Level settings apply to Training and Match modes. The range extends from beginner-friendly Fun Levels to ratings above 2100 ELO.

Chapter 8

Review the Game

L6 stores replay data for up to three completed games. Open Review to select a game. The upper area shows the position; the lower area shows the move list and score for each move.

Use Up and Down to move through the game. During replay, press Play/Pause on a selected position to begin playing from that point. A game started from replay is not stored as a new review record.

Chapter 9

Puzzle

The L6 includes 1,000 puzzle exercises. Select Puzzle from the main menu, choose an index with Up or Down, and press OK.

The display shows the required position and the corresponding board lights help you place the pieces. After setup, the voice announces whether White or Black moves. An incorrect answer produces a beep and a red destination-square light.

Chapter 10

Start from a Position / Set Pieces

Use Setup → Set pieces to analyze an interesting position, continue from a saved idea, or create a puzzle. Place White's pieces first, then Black's pieces. If a piece is placed incorrectly, remove it and place it again.

After the position is complete, press OK and set:

Color to move

Select White or Black as the side that moves first.

Bot color

Power Save and Force Shutdown

After approximately 30 minutes without activity, the L6 enters sleep mode. If a game is in progress, the position is saved so it can be restored after the device is turned on again.

Chapter 14

Maintenance and Support

Handle the L6 carefully and keep it away from excessive moisture, impact, electromagnetic interference, and static discharge. Clean the board with a soft, slightly damp cloth. Do not use abrasive or aggressive cleaning fluids.
