Frequently Asked Questions - AWMS-NDB Atdec

What tools are needed to install the Atdec AWMS-NDB?

You need a Phillips head screwdriver and the provided 4mm and 5mm Allen keys.

What is the weight capacity for a flat monitor on this mount?

The flat monitor weight capacity is 0-9 kg (0-20 lbs).

How do I adjust the arm tension if the monitor sags?

Use the 4mm Allen key to turn the tension screw clockwise to increase tension until the device stays in position.

Can I use this mount with a curved monitor?

Yes, but the weight capacity is reduced to 0-6 kg (0-13.5 lbs) for curved monitors.

What desk thickness range does the F-Clamp support?

It supports desks from 0 to 79 mm using two clamp positions: normal (0-36 mm) and inverted (36-79 mm).

How do I set the arm to rotate only 180 degrees?

Remove the plastic sleeve, take out the rotation ring, and reposition it with the tag facing the user for 180° rotation, then replace the sleeve.

Is the mount VESA compatible?

Yes, it supports 75x75mm and 100x100mm VESA patterns. For other sizes, use an optional adapter plate.

How do I manage cables with this arm?

Plug cables into the device, then route them down the arm using the cable hooks and clips. The cables can be wedged into the central gap and slid down into the arm cavity.

What is the purpose of the plastic cap on the base?

The plastic cap must not be removed or thrown away – it is essential for proper operation of the mounting base.

Can I attach a VESA monitor directly without the notebook tray?

Yes, you can convert the system: attach the VESA head (AWM-HN VESA head) to the display and insert it into the arm; secure with the lever.

IMPORTANT INFORMATION

! Please ensure this product is installed as per these installation instructions.

! Do not remove/ throw away the plastic cap on the base.

! This product is compatible with Atdec AWM Series products.

! Curved monitors, deep devices (such as all-in-one PCs) and offset VESA locations exert additional leverage that can exceed the capacity of the mount even though the monitor weight may be within the stated range.

! The manufacturer accepts no responsibility for incorrect installation.
