1.7 IRMA Cartridge Care
Unpacking the IRMA Cartridges
IRMA cartridges are ordered, packaged, and shipped under separate
cover in an insulated shipping container. The shipping temperature
range is 0 to 50°C. Check the temperature indicators that are
included in each shipping container. Refer to the instructions that
accompany the indicators. If the temperature indicators show that
the shipping temperature range has been exceeded, do not use the
cartridges. Call your service provider for replacement cartridges.
Store the cartridges at room temperature. Refer to Appendix B,
Section B.7 for additional cartridge storage information.
Equilibrating the IRMA Cartridges
All cartridges must be equilibrated before use. Remove the cartridges from their shipping container and equilibrate to room
temperature in an area that has a stable temperature between 15 to 30°C (59 to 86°F) with no uctuations greater than 8°C
(14.4°F). Equilibration times vary by product and are found in Appendix B, Section B.7.
If the storage area temperature uctuations are greater than 8°C or 14.4°F, the cartridges must go through an additional
equilibration period before they can be used. Proper conditions should be documented by recording the daily minimum and
maximum storage area temperatures.

1.10 IRMA Touchscreen Interface
The IRMA Tablet uses a combination of symbols, text, video, controls (buttons, spinners, text entry and checkboxes) and
motions (pressing, swiping and pinching) through which the operator interacts and controls the IRMA System to perform
testing, review test results and congure the IRMA System. The user is guided through each procedure using screens
containing easy to understand directions, buttons, graphics, and video clips (where appropriate).
IRMA Controls
The operator uses buttons, spinners, checkboxes and text entry areas to perform actions and input data into the IRMA System.
Buttons
The various types of buttons the IRMA Touchscreen Interface uses are:
• Selection: Selection buttons are used to navigate through
the IRMA Touchscreen Interface and vary in shape and color.
• Action: Action buttons are green, orange or blue and appear
at the bottom of the screen or in the keyboard area. They
perform the action of the text displayed on them.
• Multi-Select: Used to input data or congure the IRMA
System. Zero or more buttons may be selected. A multi-select
button turns blue and displays a checkmark in it when select-
ed. When de-selected it is grey with no checkmark.
• Radio Button: Used to make a single selection. A radio but-
ton turns blue and has a dot inside the circle when selected.
When de-selected it is grey with only a circle displayed.

there are a limited number of possible entries. To use the spinner
control:
• Touch the center of the control and swipe up to change the
selection to a selection below the center position. Swipe
down to change the selection to a selection above the center
position.
• If there is no text above the center position the spinner can
only be swiped up. If there is no text below the center posi-
tion the spinner can only be swpied down.
• The selection in the center blue box is the selected data
point.
Checkboxes
The checkbox control is used to turn a function on a screen on or o.
• Press the box once and a checkmark appears in it. The func-
tion is on.
• Press the box again and the checkmark is removed. The
function is o.
Text Entry Area
The text entry area is used with the keyboard or barcode reader. It is
described below under the Keyboard Screen.
Motion Controls
The IRMA Tablet uses a touchscreen that is responsive to the following motions controls:
• Pressing: Touch the screen with your nger or a stylus make a selection.
• Swiping: Touch the screen and then drag your nger or a stylus either up or down (scrolling) or drag it either to the
right or to the left (swiping.) When there is additional information displayed on a screen, as indicated by a thin, verti-
cal, grey line, it is viewed by scrolling the screen.
- When multiple test records are retrieved from a search (Section 4 - Review), moving from one record to the next is
done by swiping to the left or right.
• Pinching: Touch the screen with two ngers and slide the tips of each nger together to zoom out of the text. Touch
the screen with two ngers close together and spread the tips of each nger away from the other to zoom in on the
text. The user manual is the only portion responsive to pinching.
Note: Touchscreen sensitivity varies from individual to individual and may be aected by various factors like
the amount of moisture on the skin� As a result, the touchscreen performance experienced by some operators
may be compromised� For operators that experience an ongoing issue with touchscreen responsiveness, the
use of a touchscreen stylus is recommended�
Note: The IRMA Tablet's touchscreen may be used while wearing nitrile, vinyl or latex gloves� If a glove liner
is to be worn, the use of a cotton or nylon glove liner is recommended� The use of polyester glove liners is not
recommended as they have been shown to aect the touchscreen's responsiveness�
