IMPORTANT SAFETY INSTRUCTIONS
By changing the positions where the rack mount ears are
attached to the unit, it is possible to install the unit into a rack so
that its front panel is about 4 cm inside the front of the rack.
Remove the three screws that attach the rack mount ears from
each side and then use the screws to reattach the ears as shown
in the illustration below.
