3.2 Assembly
1. Check all components for completeness according to the list on page 2. Slide the control box (no. 6) out of the frame end CB (no. 3a) and
put it to one side. Separate the frame end (no. 3b) from the frame end CB (no. 3a). You will nd the centre rail (no. 4) inside.
2. Place one of the table legs (no. 1) in the frame end CB (no. 3a) and make sure that the arrow
is pointing upwards. Align the holes on the table leg (no. 1) with the holes on the frame end
(no. 3a). Using the internal hexagon supplied, insert four M6x14 metal threaded screws (no. 11)
through the holes in the frame end CB (no. 3a) into the table leg and tighten each screw slightly.
After all four M6x14 metal threaded screws (item 11) are in place, tighten all screws. Proceed in
the same way with the other table leg (no. 1) and the frame end (no. 3b).
3. The frame end CB (no. 3a) should be placed on the side of the desk where you want to mount
the control box (no. 6) and the switch (no. 7). Slide the side bracket (no. 5a) into the frame end
CB (no. 3a). Insert two M6x35 metal threaded screws (no. 12) through the two holes in the top
of the side bracket (no. 5a) into the frame end. Tighten each screw slightly using the internal
hexagon supplied. After inserting the two M6x35 metal threaded screws, tighten the screws. Do
the same for the other frame end/leg assembly.
4. Slide the two centre rails (no. 4) into the two frame ends
(no. 3a and 3b). Note:
a. The grooves in the centre rails (no. 4) point inwards.
b. The grooves in the centre rails (no. 4) are closer to the upper edge, as the assembly is „overhead“.

5. For each leg assembly, fasten one foot (no. 2) with four M6x14 machine screws (no. 11)
and tighten them crosswise.
6. The table top can be pre-drilled. Therefore, check both sides of the table
top before assembling the table frame on the underside. Adjust the width of
the table frame to the table top by sliding both halves outwards. We recom-
mend allowing at least 1.3 cm of the table top to protrude over the frame
width and centring the side brackets in this position.
7. If the table top is pre-drilled, follow step 8 before step 7. If this is not the
case, secure the position of the centre rail (no. 4) with eight M6x10 metal
threaded screws (no. 10).
8. Check that the wooden screws are not too long and do not drill through the
surface.
We recommend that you pre-drill all the holes required for xing the table
top. Never use countersunk screws.
Check again that the table frame and table top are correctly aligned. Fasten
the table frame to the underside of the table top using seven M5x20 wooden
screws (no. 13).
Install the switch (no. 7) so that its front is ush with the front edge of the table top. The switch can be attached anywhere
along the table top, but we recommend that you place the switch at the end so that it does not hamper you when sitting. Use
two M5x16 wooden screws (no. 14) to fasten the switch to the table top.
Do not overtighten the screws in this step. Overtwisting causes damage to the components.

9. Connect the cable that runs through the leg attached to the frame end CB
(no. 3a) to the control box (no. 6). Slide the control box (no. 6) onto the frame
end CB (no. 3a). Connect the cable (no. 9) to the other leg (no. 1) and the
control box (no. 6).
Connect the power cable (no. 8) to the control unit (no. 6).
Use the self-adhesive cable clamps (no. 15) to fasten the cables so that they
do not sag.
10. Set up the desk with at least two people. Grasp the table frame (not the table top) and turn the desk over. Adjust the
pre-installed sliders to the feet as required.
11. Plug the power cable into a 230 V socket.
4. Use
Make sure that there are no obstacles that prevent the table from moving up and down. Ensure that the desk top is not
touching any walls and that all cables are of the required length for each desired height change.
IMPORTANT: You must reset the electronics before use.
RESETTING: Press and hold the down key on the switch until the desk reaches its lowest height. Release the down key. Press
and hold the down key again until the LED display shows „RST“ (10 seconds for non LED displays). Release the down key. Press
and hold it again until the desk descends a little, rises slightly and stops. Release the down key again. Your desk is now ready
for use. The table frame can be adjusted by pressing the key up or down until the desired height is reached.
Programming the memory function for the handset control:
Due to the automatic height adjustment, there is an increased risk of crushing when using the control element hand switch
with memory function. Therefore, make sure that there are no persons or objects in the danger area and that no one reaches
into the danger area.
Use the up/down key to obtain the desired height, then press „M“ followed by a number 1-4.
ATTENTION: As soon as a preset key is pressed, the desk moves to the programmed height (see the warning above).

5. Troubleshooting
If your desk is not functioning properly, the electronics may have to be reset. Follow the reset procedure described in the section
„Use“. If your desk has a switch with an LED display and shows „RST“, carry out the reset procedure described in the „Use“ secti-
on.
If the LED display shows the error message „ER1“ – „ER13“, check all electronic connections (legs – cable, cable – control box).
Then carry out the reset procedure. If the error message is still displayed after the reset procedure, contact your dealer.
If there is a height difference of more than 3.81 cm between the table legs, stop the reset procedure and contact your dealer. If
the LED display shows „HOT“, allow the table frame to cool down for 20 minutes.

7. Setting the LED return height
KCalibration of the height measurement: Press the down key on the switch until the frame has reached the lowest position.
Measure the height of the frame from the oor if the number on the LED display does not match your measurements,
proceed as follows:
Press and hold the Down key until the display shows „RST“.
Press and hold the „M“ key (approx. 5 seconds) until the LED indicates the ashing start height. (If the display changes to
„RST“ before the next step, repeat this step).
Change the value of the initial height::
= ne adjustment
Keys 1 and 2 = medium
Keys 3 and 4 = grobe Einstellung
As soon as the new value is displayed, wait about 5 seconds and the display will show „RST“ again. End the reset process by
pressing and holding the down key until the desk descends a little, rises slightly and stops. Now release the key. The new
starting height is stored, and your desk is now ready for use.
Note: The LED display has a tolerance of 0.1

8. Setting the upper and lower limits
This product has been designed to give you the widest possible range of positions with the lowest and highest settings. If you
do not want to use them, change the settings individually in the following steps:
Make sure that the power is on and a number is displayed in the LED display (if no number is displayed, please follow the reset
procedure in the „Use“ section).
Set the highest position:
Use the Up/Down key to move the frame to the desired maximum position. Keep the „M“ key pressed until „S“ ashes once
in the LED display and then release the key. Then press the key twice in quick succession. The LED display changes to „999“
when the key is pressed for the third time and then automatically returns to the selected height. The highest position is set.
Fix lowest position:
Use the Up/Down key to move the table frame to the desired lowest position. Keep the „M“ key pressed until „S“ ashes once
in the LED display and then release the key. Then press the key twice in quick succession. The LED display changes to „000“
when the key is pressed for the third time and then automatically returns to the selected height. The lowest position is set.
To remove the position settings:
Use the Up/Down key to move the table to a new position. Keep the „M“ key pressed. As soon as the LED display ashes „S“
once, release the key. Then press the „M“ key again until the display changes to „555“ (ignore interim results). Release the key.
After a few seconds, the display automatically returns to the numbered height position. The upper and lower limits have now
been removed.
During the reset procedure, the table frame is completely retracted. Make sure that there are no objects under the desk.
If the settings of the lowest and highest positions are set again, it is possible that the set positions 1, 2, 3 or 4 can no longer
be approached. If this happens, readjust the position.
If you intend to change the lowest and highest position which is outside your position setting, a new reset is necessary.

9. Programming change from constant pressing to single pressing
Presetting the handset with memory function for e-desk:
After programming a key (1-4 for a desired height) it must be kept pressed constantly. The system then stops automatically at
the programmed height.
Reason: Safety aspect. By pressing constantly, the user retains control of the system at all times.
The function can be reprogrammed from constant pressing to single pressing as follows:
Keep the button with the down arrow on the handset pressed until the lowest position is reached. Release the button and
keep it pressed again until the LED display shows RST.
Press and hold the button labelled 1 for about 5 seconds until the RST indicator starts ashing and the display changes as
follows
10.1 = Single pressing mode (i.e., the button with the programmed height is pressed once briey and the system then auto-
matically moves to the programmed height by itself)
10.2 = Constant pressing mode (i.e., the button with the programmed height must be kept pressed constantly to reach the
programmed height)
Then release button 1. Press button 1 again until the desired setting (10.1 or 10.2) is shown. As soon as the desired setting
appears, release button 1 again and wait about 5 seconds until the display shows RST.
To complete programming, press the button with the down arrow until the table moves down a little, then briey up again and
nally stops. Then release the button. The new programming is now stored, and the table can be used accordingly.
