Mechanical Instructions EN 9 LC4.9E AB 4.
The aluminium stands (order code 3122 785 90480) can be
mounted with the back cover removed or still left on. So, the
stand can be used to store products or to do measurements. It
is also very suitable to perform duration tests without taking
much space, without having the risk of overheating, or the risk
of products falling. The stands can be mounted and removed
quick and easy with use of the delivered screws that can be
tightened and loosened manually without the use of tools. See
figure above.
Note: Only use the delivered screws to mount the monitor to
the stands.
