This document provides a user manual for the J.BURROWS Matrix Executive Electric Height Adjustable Desk, models JBMATEL12K and JBMATEL15K. It outlines the setup, operation, and troubleshooting for this electric desk.

Function Description:

The J.BURROWS Matrix Executive Electric Height Adjustable Desk is designed to allow users to easily adjust the height of their desk, promoting ergonomic working positions. It features an electric motor system for smooth height adjustments, memory settings for preferred heights, and various protection mechanisms to ensure safe and reliable operation. The desk is intended for use in office or home office environments where frequent height changes are desired.

Usage Features:

1. Learning Process & Stroke Reset:

   • Initial Setup: After initial assembly, a learning process is initiated by pressing the "up" and "down" buttons simultaneously for 3 seconds. This calibrates the desk's movement range.
   • Stroke Reset: If the desk loses power or displays error codes like "E10," "E20," or "E60," a stroke reset is required. This is performed by pressing the "down" button for 3 seconds until "FE5" appears. The desk will then automatically move to its lowest point, rebound slightly, and display the lowest height, completing the reset and learning process.

2. Lifting (Height Adjustment):

   • The desk's height can be adjusted by simply pressing the "up" or "down" buttons.

3. Height Memory Setting:

   • Saving a Position: To save a desired height, move the desk to the preferred position using the "up" or "down" buttons. Then, press the "M" (memory) button, which will cause the display to blink. Within 5 seconds, press one of the numeric keys (1, 2, or 3) to assign that height to the corresponding preset. The display will stop blinking, indicating the height has been saved.
   • Recalling a Position: Once heights are saved, pressing the assigned numeric key (1, 2, or 3) will automatically move the desk to the stored height.

4. Setup Mode:

   • Accessing Setup: To enter setup mode, press and hold the "M" button for 3 seconds. The display will show "S--" and blink.
   • Navigation:
     • The "M" button is used to cycle through the different setup menu functions.
     • The "up" and "down" buttons are used to select options within a submenu.
     • The "M" button also acts as an "Enter" key to confirm selections or move to the next menu.
     • The "backspace" key (likely the "M" button pressed briefly or a dedicated button not explicitly labeled but implied by context) allows returning to the previous menu or exiting setup mode.
   • Automatic Exit: If no numeric key is pressed within 20 seconds while in setup mode, the system will automatically exit.

5. Setup Menu Functions:

   • Unit (Un):
     • Description: Allows selection of the display unit for height, either centimeters (SI Metric) or inches.
     • Operation: Use "up" or "down" to choose "SI Metric" or "Inch," then press "M" to confirm and save. The system exits setup mode after 2 seconds.
   • Brightness (br):
     • Description: Adjusts the brightness level of the controller display. Options include "Low," "Normal," and "High."
     • Operation: Use "up" or "down" to select the desired brightness level, then press "M" to confirm and save. The system exits setup mode after 2 seconds.
   • Beep (bEE):
     • Description: Toggles the beep sound on or off.
     • Operation: Use "up" or "down" to choose "Off" or "On," then press "M" to confirm and save. The system exits setup mode after 2 seconds.
   • Collision Force (CF):
     • Description: Sets the sensitivity of the collision protection feature. Options include "Off," "Light," "Normal," and "Heavy." This determines how easily the desk detects an obstruction and stops movement.
     • Operation: Use "up" or "down" to select the desired sensitivity, then press "M" to confirm and save. The system exits setup mode after 2 seconds.
