Getting started
Your box contents will include: the Vertical assembly, the Horizontal arm assembly, the Instruction manual, the Fixing pack and the Power supply unit.
Thread the power connector through the slot at the base of the clamp and press the power connector into the socket.
Remove the cardboard transit packaging at the top of the clamp and slide the vertical assembly down into the clamp.
Use the larger Allen key to loosen the clamp enough to reveal the screw recess.
Use the small Allen key to tighten the long silver screw until it sits flush with the face of the clamp.
Push the clamp squarely onto the desired surface.
Use the large Allen key to tighten the clamp until the light is held secure.
Remove both pieces of red tape covering the electrical contacts.
Align the square shapes and screw holes on the heat sink arm and the vertical assembly.
Locate the tab on the Horizontal assembly plate into the hole on the vertical assembly plate and secure using the three screws.
Remove the transit tape and all packaging from the product.
Plug in the Power supply unit. Using at least two fingers gently press the on/off touchpad to turn on the light.
The light can be adjusted, vertically, horizontally and rotate through 360°. Adjust the position of the light by moving the arm not the weight.
CSYS lights have touch-sensitive, continuous dimming. Adjust the level of the light you need by keeping your fingers held on the on/off touchpad.
