Your Extension’s Accessories

Installing Add-on Key Panels

You can install your add-on key panel without any particular tools 

or accessories.
These panels are connected using a rigid connector designed to 

attach the first satellite to the underside of your extension, and 

each subsequent satellite to the underside of the previous one.
These modules are held in place by a tulip-shaped pin that is inserted 

in the appropriate hole on the underside of your extension or the 

previous satellite, as well as the plastic slots located along the edge 

of your extension or satellite.
So, to install any satellite, simply follow the directions illustrated in 

the following diagram:
•

With your extension upside down, position the new satellite 

along the edge of your extension or previous satellite.

•

Press firmly on the bottom of the satellite in order to correctly 

insert it onto your extension or the previous satellite.

When removing a satellite, press firmly on the top in order to 

disconnect the plastic connector and the tulip-shaped pin.

Just as with your extension, each satellite has a support foot that 

can be installed and adjusted to one of two positions, according to 

the angle you have set for your extension.
