2.1.3 Icon Keys
The four icon keys directly to the right of the display screen correspond to the different icons displaying on
the screen. Selecting an icon key displays another screen or directs the instrument to perform an action.
2.1.4 Keypad
The keypad contains 13 labeled keys located directly below the display screen. The “0” through “9” keys
are used to enter operator and patient identification numbers, change the time and the date, and make
selections from menu options. They can also be used to perform numeric entries. The right ( ) and left
( ) arrow keys move the cursor as needed and work as toggle switches within certain screens. The Tab
key is used to move the cursor from field to field within certain screens.
2.1.5 Power Switch and Indicator
The power switch is located on the back of the instrument (“I” designates on, “O” designates off). When
the instrument is initially powered on, a series of internal diagnostics occurs, which takes approximately 30
seconds. When power is on, a green LED indicator on the lower left corner of the keypad remains illuminated.
Place the instrument in a location that allows adequate access to the power switch and power cord.

2.1.6 Bar Code Scanner
The bar code scanner is located on the left side of the instrument (Figure 2-4). When activated, it
illuminates a bar code light so that the bar code on the white test pouch can be presented by the user
to be scanned, decodes the bar code, and transmits the information to the instrument software. The
instrument software identifies the test device expiration date and lot information.

2.1.7 Fan
The instrument is equipped with an exterior fan vent next to the bar code scanner to cool the internal
electronic components. Avoid placing equipment adjacent to the fan that obstructs airflow. Periodic
cleaning of the fan filter may be performed to avoid overheating of the instrument. See section 9.3 for
fan filter replacement instructions.
