Mounting Configurations

The EMS-4001 mounts in a standard 19 inch equipment rack and is 1 rack unit high. Install the two supplied rack mount cosmetic covers when installing the EMS-4001 in the rack.

When rack mounting components, you may not be able to access the sidetone trimmers after the components have been mounted. In this case, you can position the components in the rack and make all required connections. Then adjust the sidetone trimmers before installing and tightening all rack mount screws.
