To reassemble using the replacement assembly, perform steps 6–7 in reverse
order, being careful to align the display screen before tightening. Check the
lithium battery plug for proper installation on the connector.
Note that the termination panel to digital controller ribbon
cable pin 1 wire is not red. On the digital controller board, the
red edge (pin 1) of the cable should plug onto pin 50, the right
side of plug. The plug is keyed; do not force the plug into the
connector.

Re-plug the ground cable onto the new assembly.

Once assembled, apply power to the NGC (Step 5).

contrast, use an extra small Phillips point screwdriver to turn the potentiometer
R18 clockwise for more contrast or counter clockwise for less.

Reinstall front and rear end caps.
To return this assembly to Totalflow service for warranty or
repair, contact Totalflow customer service for an RA number.
Keep the lithium battery connected to the digital controller
board for return.
Note that since power was removed from this unit, the NGC
will perform start-up diagnostics and stabilize. If the user has
disabled the start-up diagnostics, they should be enabled and
power cycled to the unit. If the power has been withheld from
the unit for an unknown or lengthy period of time, a complete
start-up should be performed.
