The Multiplanar Accessory Housing Joint, the shelves and all of the accessories can be attached to the
end of either of the ER arms.
Interchanging different ER accessories or attachments has been described in detail in the previous
section on the Multiplanar Accessory Housing Joint.
Adjusting the height of the lower ER arm
The height of the lower ER arm is controlled by two mechanisms, which
are both located on the left side of the ER stand (left is defined as
your left when you are facing the ER).
If you follow the ER arm to its attachment on the stand, you will
notice a long handle with a round black end (wide arrow). This
long handle is a general locking and release mechanism for the
lower ER arm.
If you turn the long handle clockwise you will be locking the lower
ER arm and preventing any movement from occurring. If you turn
the long handle counterclockwise you will be unlocking the lower
ER arm, which allows movements to occur.
Immediately in front of the long handle is a round button with the
words “push to unlock” and a picture of a hand on it (curved
arrow). This button is a safety locking mechanism for the lower
ER arm.
Raising or lowering the lower ER arm
Identify and grip the long handle at the end of the lower ER arm (where the arm meets the ER stand).
This long handle is located on the left side of the ER stand when you are facing the ER.
Grip the handle and turn it in a counterclockwise direction. To lock or unlock the lower ER arm
movements, it is only necessary to give the handle a ¼ turn.
