Memory Presets:
The control panel allows you to save up to four preferred height settings. To set a memory position:
- Adjust the desk to your desired height using the up/down arrows.
- Press the "M" button (or similar memory set button) once.
- Press one of the numbered preset buttons (1, 2, 3, or 4) within a few seconds. The display will confirm the setting.
To recall a saved height, simply press the corresponding numbered preset button (1, 2, 3, or 4). The desk will automatically move to that height.
