Installing the V2403C

The V2403C computer comes with two wall-mounting brackets. Attach

the brackets to the computer using four screws on each side. Ensure

that the mounting brackets are attached to the V2403C computer in the

direction shown in the following figure.

The eight screws for the mounting brackets are included in the product

package. They are standard IMS_M3x5L screws and require a torque of

4.5 kgf-cm. Refer to the following illustration for details.

Use two screws (M3*5L standard is recommended) on each side to

attach the V2403C to a wall or cabinet. The product package does not

include the four screws required for attaching the wall-mounting kit to

the wall; they need to be purchased separately. Ensure that the

V2403C computer is installed in the direction shown in the following

figure.
