With the template in place against the cabinet panel, mark the
"A" and " B " drill holes and the four small holes that identify the

With the saw on the INSIDE OF THE PENCIL LINES carefully cut
out the rectangular opening.
Secure the mounting strips to the rear of the cabinet panel using
two screws from the hardware package.
Insert the screws in the center holes of the cabinet panel ("B"
holes on the template) and tighten. The screw head should pull
into the wood slightly. (Use two ¾ inch long screws for panels under
½ inch, or two 1¼ inch long screws for panels ½ inch thick and
larger.)
Attach the mounting brackets to the cabinet panel using four
screws.
Place the template over the mounting screws. The mounting
screws should be centered in the "A" and " B " holes on the tem-

plate. The sides of the mounting brackets should match the vertical
dash lines on the template. If necessary, loosen the screws and
push the brackets into alignment and retighten.
Insert the power cord through the opening. Carefully slide the
MR 73 into the opening so the rails on the bottom of the equipment
slide in the track of the mounting brackets. Continue to slide the
instrument in until the front panel is against the cabinet panel.
At the bottom front corners of the PANLOC instruments are the
PANLOC buttons.
Depressing the PANLOC buttons will lock the instrument firmly
in the installation.
Depressing the PANLOC buttons a second time (as with a ball-
point pen) will release the instrument. You can then slide the
instrument forward to the inspection-adjustment position.
Depressing the inspection-adjustment position latches will allow
the instrument to be slid completely out of the installation.
VERTICAL INSTALLATION
In the hardware packet are two helical springs. Fasten the springs
to the small flanges at the rear of the PANLOC brackets. The flange
has a notch and a hole to mount the spring. The springs assist in the
removal of vertically mounted PANLOC equipment.
