These internal jumpers (W102 through W802) are for special applications which are

not applicable to the EMS4000. Leave the jumpers in the factory default position

(pins 2 & 3 shorted).

Sidetone Trimmers

These trimmers are normally adjusted after all components are connected, and they

can be accessed through the bottom cover (Figure

3

). Refer to the MS2000 User

Manual for the sidetone adjustment procedure.

Mounting Configurations

The EMS4000 mounts in a standard 19 inch equipment rack and is 1 rack unit high.

Install the 2 supplied rack mount cosmetic covers when installing the EMS4000 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.
