Common Procedures
How to synchronize the desk:
(Initialization)
1. Move objects from under the desk that may
impede the lowest height when the desk is
fully lowered (e.g. storage, chairs).
2. If items are attached to the desk
(e.g. privacy screens, computer), make sure
they are free from obstruction too.
3. Adjust the desk to its lowest position and
release the Controller or Down button.
4. Press down on the Controller or Down
button again and hold for 10 seconds.
When synchronized, the desk will move
up and down slightly.
5. Raise the desk all the way up to ensure
cords are not disconnecting. Then lower all
the way down to confirm proper function.
Every desk must be synchronized
periodically for proper use.
After replacing parts, the desk
must be synchronized.
Power-saving Control Box:
•The Control Box automatically powers down into ‘Standby’ mode after
approximately 10 seconds of inactivity.
•During Standby mode, the Control Box only consumes 0.1 watt of power.
•With the Control Box in Standby mode, the desk can lose power without
affecting the synchronization of the Lifting Columns.
•However, if the Control Box is still active and not in Standby mode, a
power loss will require that the Lifting Columns be re-synchronized.
•Power fluctuations and brownouts can also cause the need for
re-synchronization.

How to test Lifting Columns:
Lifting Column can be operated independently, even if they are sitting
on a table, not assembled into a Desk.
1. Obtain a Control Box that is known to work. Be sure the Control
Box is unplugged, or plugged in but in Standby mode.
2. Connect the Low-Voltage Cable of the Lifting Column to the
known-good Control Box. Connect only to Port/Channel 1
(farthest from the Power Cable).
3. Obtain a Controller that is known to work, and connect it to the
Control Box. Tip: Verify that the Control Box software is current.
4. If the Control Box is unplugged from the wall outlet, plug the
Power Cable back in.
5. Operate the Lifting Column.
A. Can the Lifting Column be operated through its full range
of motion?
B. Does the Lifting Column appear to function normally?
Any faulty Lifting Column must be replaced. There are no
field-serviceable parts inside the Lifting Column.

No power to desk:
1. Check for power at the outlet. Refer to
product ratings.
2. Check that the Power Cord is fully seated
in the Control Box.
3. Inspect the Power Cord for defects;
replace the defective cord.
4. Check that all cables are connected per
the Assembly Directions.
