3. Installing MRE-280
3.1 Applicable radar models
The MRE-280 can be installed in the MDL-1140 and MDC-1040 series radar sets.
3.2 Installing the ATA PCB
Turn off the radar set completely and switch off the main power at the distribution panel before carrying
out the following procedures.
(1) Remove all cables connected at the display rear panel and remove the two knurled fixing nuts that
fasten the display unit to the base mount. Remove the display unit from the mount.
(2) Put the display unit with the front face down in a safe flat area. Use a cushion to protect extruded
control knobs.
(3) To remove the front panel and chassis, remove the tapping screws No.3 (8 screws), fastening the
front panel No.1 to the rear panel chassis No.2, and then remove the 2.5 mm screws No. 5 (2
screws), which fixes the optional connector to the rear panel, to allow the front panel and chassis to
be removed. During this process, be sure to disconnect the internal wire harness No.6.
(4) Put the removed front panel in a safe area. Use an appropriate cushion to protect extruded controls
on the panel.
(5) Connect the wire harness No.9 to the ATA board No.7. Use the color identification of the harness
connectors and the sockets on the board. Fasten the ATA board using the 3 mm screw No.8 (4
pieces) to the backside of the front panel, as shown in Figure 1.
(6) Connect the harness No.9 to the Logic board.
(7) Now, put the front panel back in the original position. Move the front panel No.1 closer to the rear
panel chassis No.2 and connect the internal harness No.6.
(8) Push the front panel No.1 into the rear panel chassis No.2. Be careful not to allow the LCD
backlight harness to get pinched between the two sections.
(9) Secure the tapping screws No.3 (8 screws) to fasten the front panel to the chassis. Also fasten the
optional connector to the rear panel chassis using the 2.5 mm screws No.5 (2 screws).
(10) Connect the power cable to the display unit and turn the unit on.
(11) Open the SET UP menu and select CUSTOM. Confirm that ATA PRESET is added.
(12) Turn off the power and reset the display unit onto the base mount. Do all remaining connections at
the rear panel.
