the cover toward the rear of the chassis. (See Figure 1.)

Replace the Chassis Cover

components, prevents electrical shorts, and provides proper air-flow for cooling the electronic components.
To replace the chassis cover, perform the following steps.
Procedure
1. Place the chassis on a secure surface with the front panel facing you.
2. Lower the front of the chassis cover onto the chassis, slide it forward until it fits into place, and tighten the
thumbscrew to secure the chassis cover. (See Figure 2.)
