E&M Jumper Block Positioning Procedure

A jumper block exists for each voice/fax channel. The jumper block is to the right of each set of channel jacks. The jumper block contains 8-pairs of pins. The jumper plug fits over three pairs of pins on the jumper block. The E&M type number is labeled on the pc board. The jumper plug needs to be centered on the E&M type number. Perform the following procedure to change E&M jumper position.

1Ensure that power is removed from the MultiFRAD.
