4. Verify that the scanner or scanning-scale passes an operational test 

by observing the following:

Pass UPC/EAN bar code labels in front of the scanner’s win-

dows. Since the interface cable is not yet connected to the POS 
terminal, the scanner may be limited to reading only one or two 
labels (see the note that follows). The scanner indicates when each 
label has been successfully read by flashing the green scanner light 
and emitting a good read tone (beep).

If the Yellow LED is not lit, press the Scale Zero Push Button 
momentarily. If the scale is operating correctly, the yellow LED 
will illuminate and remain on steady, and the display will show a 
reading of 0.00 lb (0.000 kg for metric). If the display is blank or 
a 

is displayed, it may be necessary to calibrate the scale 

before continuing. Refer to Section 5, Calibration, for calibration 
procedures.

Check to verify that 0.00 lb (0.000 kg for met-

ric) is displayed, then place an item on the weighing platter. Ver-
ify that the display shows a weight and that the yellow LED goes 
out. Remove the item and observe that Remote Scale Display 
shows 0.00 lb (0.000 kg for metric) and that the yellow LED is 
On.

5. Unplug the AC power cord from the outlet and disconnect the 

power cord and Remote Scale Display cable from the scanner’s 
connector panel.

After you have verified that the scanner and scale (if present) are com-
pletely functional, continue with the following procedures to complete the 
installation.
