iii. When the platter is flush, its leading edge should be slightly below the checkstand, and the trailing 
edge should be slightly above the checkstand.
To ensure smooth scanning, replace the platter, take a steel can (like a soup can), turn it over so the 
harsher seam is facing down, and slide the can over the platter in the standard scanning direction. The 
can must not catch on the checkstand or the platter when swept across all sections of the platter, in the 
correct direction.
4. Route all cables through the checkstand as shown in 
Figure 3-3
.
5. Connect all cables to the MP70XX and POS, as needed (e.g., scale, Scale Display, Checkpoint antenna, or 
Sensormatic coils, POS, CSS, etc.).
6. Power up the MP70XX. Upon power up, the MP70XX verifies that all sub-systems, and auxiliary devices are 
operational. If a fault condition exists, an error condition displays on the 7-segment display, and the startup 
sequence halts. Power cycling is required after rectifying the problem. (See 
General Error and Warning Codes 
on page A-4
)
If a scale is present, warm-up time for the scale is 30 minutes (assuming room the temperature is
70° F/20° C).

IMPORTANT Standard length leveling screws ship with all short and medium models (kit MX301-SR00004ZZWR).
Longer length screws are available as an accessory (kit # MX302-SR00004ZZWR)
 contains four 
extra-length screws which will protrude 1" inch (25 mm) below the bottom of the unit. See 
Figure 1-5 on 
page 1-10
 for the installation location of these screws and for the locations of access holes for turning 
the screws from above.
IMPORTANT Most accessories (scale, Scale Display, Checkpoint interlock, Sensormatic coils, Sensormatic RS-232 
cable, CSS, and auxiliary RS-232 scanners) must be installed and connected to the MP70XX prior to 
applying power to the MP70XX.
