OPERATION
INFORMATION
INITIALIZATION/RESET
The desk must be initialized/reset after any of the following:
- After assembly
- After disconnection from the power supply
- After any impact on the table top.
To initialize/reset, move the table to the lowest position by pressing the DOWN button on the handswitch until
the columns reach the lowest position. Press the DOWN button again until the table moves slightly down to
the machine zero point and back up to the operation zero point. Release the DOWN button. If the button is
released too soon, the table legs will not move up. Repeat the reset process.
The control box is programmed with a parameter le which controls the table legs’ lower and upper travel
limits. Under no circumstance should a control box from one table be moved to another.
NORMAL HANDSWITCH OPERATION (for all handswitch types)
By pressing the UP or DOWN buttons, the table will move up or down to the desired position. Once the
desired position is reached, let go of the UP or DOWN button. The table legs will stop once they reach
the lower or upper height limits.
PROGRAMMABLE HANDSWITCH OPERATION (NOT STANDARD)
This programmable handswitch is
equipped with a display for showing
the current table height in centimeters
or inches.
The handswitch also will display an error code if an error is detected by the control box. When an error
is detected, the display will show an error code “EXX,” instead of the current table height. To resolve the
error, see the Troubleshooting Section (p. 17-18 of this guide).
The programmable handswitch also has the ability to save up to four different height positions.

To exit the menu without making a selection, wait until the height display appears again.
CHANGE THE HEIGHT DISPLAY
If the displayed value does not match the actual height of the table top, the display can be corrected as follows:
1. Press and release the “S” button.
2. Press and hold the DOWN button until the display starts to ash.
3. Change the height shown on the handswitch by pressing the UP or DOWN button to the desired height.

measure was changed.
To exit the menu without making a selection, wait until the height display appears again.
SAVE MEMORY POSITION
1. Move the table up or down to the desired height.
2. Press the “S” button (in the display “S -” is shown.)
3. Select a position by pressing one of the four number buttons, 1-4, (if 1 is selected, the display will show the
setting as “S1”).
4. The saved position is conrmed by a double click sound from the control box. The display shows the current
table height. Repeat steps to save a maximum of four different positions.
RECALL MEMORY POSITION
Press and hold the desired memory button (1, 2, 3 or 4) the table moves from the current position into the
