Arrow and Decimal Point Keys

Each of the four digits in the display is associated with the up arrow key directly below it. When applicable, the
arrow key is used to increment the value of that digit, or advance to the next selection in a list of functions or
settings.

Each press of an up arrow key will increase the digit by 1, up to 9, and then back to 0. The arrow keys may also be
held down for continuous incrementing of numbers. Some parameters, such as the RS-232 baud rate, scroll
through a selection of values when the arrow keys are pressed. Other parameters have a fixed range of values, such
as some setup parameters that are either turned on or off. In these cases, the arrow key will only scroll up to the
maximum value for that parameter, then back to the minimum value.

When changing the pumping rate units, each press of any arrow key will change the units LEDs to the next units
selection.

When the display blinks, the new value is stored and takes effect. This will occur when a non-arrow key is pressed
or after a 2 second delay since the last key press.

5.4.1

Decimal Point

There are 4 decimal point positions on the LCD display. Each decimal point position is to the right of a digit in the
display. The last decimal point position, to the right of the right-most digit is not displayed, indicating whole
numbers with no decimal point.

To move the decimal point, simultaneously press the 2 up arrow keys under the 2 digits next to the decimal point
position. Press the same 2 up arrow keys to clear the decimal point, to display a whole number.

Alternatively, to move the decimal point position, use the left-most arrow /decimal point key (

/

). Press and

hold this key for at least 1 second and wait until the left-most digit scrolls past ‘9’ to ‘0’. While continuing to hold
this key, the decimal point will shift 1 position to the right. After the right-most decimal point position, the
decimal point will shift to the first decimal point position. Release the key when the decimal point is in the
required position.

‘Diameter’ and ‘Setup’ Key

The ‘Diameter’ key allows the syringe inside diameter to be viewed and set. While being displayed, the ‘mm’ LED
is lit. Momentarily pressing this key will display the current diameter setting. With the Pumping Program stopped,
pressing the up arrow keys will change the current diameter (see sec. 5.4, Arrow and Decimal Point Key). The
‘mm’ LED will blink while the diameter is being changed.

If the ‘Diameter’ key is pressed and held, ‘Setup’ mode will be entered. (See sec. 5.12, ‘Setup’ ).

5.6

‘Rate’ and ‘Program Phase #’ Key

When the Pumping Program is stopped, except in “Program Entry Mode”, the ‘Rate’ key allows the pumping rate
to be viewed or changed. If the currently selected function allows selection of rate units, momentarily pressing this
key will switch between the ‘Rate’ display and the select rate units mode.

To change the pumping rate displayed, use the up arrow keys (see sec. 5.4, Arrow and Decimal Point Key).

While the Pumping Program is operating, pressing this key will display the current pumping rate, if applicable.
While displayed, the current pumping rate can be changed by pressing the up arrow keys. The rate units will blink
while the rate is being changed. The new pumping rate takes effect when the display blinks after a 2 second delay
or when a non-arrow key is pressed. The new pumping rate is stored in the current Program Phase.

See section 11.7, “Syringe Diameters and Rate Limits”, for a list of minimum and maximum pumping rates. A
pumping rate of 0.0 will stop the pump. When the pumping rate is changed, if it is out of range of the pumping rate

limits, the display will show

nn

, where ‘nn’ indicates the currently selected Phase Number. Pressing any

key clears the message and returns to the previous pumping rate.

5.6.1

Pumping Rate Units

The pumping rate units can only be changed when the Pumping Program is not operating. If the currently selected
function allows selection of rate units (‘RATE’ function), a momentary press of the ‘Rate’ key will enter Rate

Units Change mode. The 2 LEDs representing the units will blink and the display will show:

.

Each press of any up arrow key selects the next rate units, as indicated by the blinking units LEDs. When the
required rate units are blinking, press any non-arrow key or wait 2 seconds. The display will blink, indicating the
rate units are stored. The rate units are stored in the currently selected Program Phase. The rate units can be
independently set for each Phase with a ‘RATE’ function.
