face, giving you direct access to the bottom of the instru-
ment.

other screws.

CAUTION
• When inserting Plug-in boards and connecting cables, make sure that you check that they are inserted and
connected properly. Improperly inserted Plug-in boards and cables may cause faulty contacts and an electri-
cal short circuit which may cause damage or result in a malfunction.
• After mounting the Plug-in board, be sure to tighten the screws as directed so it is completely stable and
does not move in any way.
