Align Refill Switch Mode:  The signal that initiates the refill phase 
can be displayed during power-up by pressing and holding the PRIME 
and the UP-ARROW buttons when the power is switched on.  Release 
the buttons when the display displays "rFL".  When the slotted disk 
allows the light beam to pass from the emitter to the detector on the 
slotted optical switch a pulse will be generated which signals the 
beginning of refill.  When this pulse occurs the three horizontal 
segments displayed at the top of the display will turn off and the three 
horizontal segments at the bottom of the display will turn on.  To exit 
this mode, press the RUN/STOP button. 
 
Serial Port Loopback Test Mode:  If an external device will not 
communicate to the pump via the serial port, the serial port loopback 
test can be used to verify that the serial port is functioning properly.  
During power-up press and hold the UP-ARROW and the DOWN-
ARROW buttons when the power is switched on and then release the 
buttons.  The display must display "C00" for the first half of the test to 
pass.  Plug in the serial port loop back plug (A modular plug with pins 
2 & 5 jumpered together and pins 3 & 4 jumpered together.).  The 
display must read "C11" for the second half of the test to pass.  To exit 
this mode, press the RUN/STOP button.
