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 setting.
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 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 a value’s 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 affect. This will occur when a non-arrow key
is pressed or after a 2 second delay since the last key press.
Decimal Point Key
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 change the position of the decimal point, use the left-most up arrow key / decimal point key (
/
).
Press and hold this key for at least 1 second and wait until the left-most digit scrolls from ‘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 displaying the
diameter, the ‘mm’ LED is lit. With the Pump stopped, momentarily pressing this key will display the
current diameter setting. Pressing the 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. 5.10, ‘Setup’ ).
When the Pump is operating, pressing this key will display the current syringe diameter for review. When
the key is released, the display returns to its previous display.
5.6
‘Rate’ Key
The ‘Rate’ key allows the pumping rate to be viewed or changed while pumping or stopped. While the
pump is stopped, momentary presses of this key will switch between the ‘Rate’ display and the select rate
units mode.
To change the pumping rate displayed, while pumping or stopped, use the up arrow keys (see sec. 5.4,
Arrow and Decimal Point Key). The rate units will blink while the rate is being changed. The new
pumping rate is entered and takes affect immediately when the display blinks after a 2 second delay or
Pumping rate units are expressed using 2 LEDs:
