With a processed 3M™ Attest™ Rapid Readout Biological Indicator, a positive (+) result
indicates a sterilization process failure. Act on any positive test results immediately.
Determine the cause of the positive 3M™ Attest™ Rapid Readout Biological Indicator and
retest the sterilizer following current facility policies andprocedures.
Optional Visual pH Color ChangeResult
3M™ Attest™ Rapid Readout Biological Indicators 1295 for Vaporized Hydrogen Peroxide
Sterilization may be further incubated for a visual pH color change. Due to the high
sensitivity of the fluorescent result, there is no advantage to continuing to incubate 3M™
Attest™ Rapid Readout Biological Indicators 1295 after the fluorescent result has been
determined and documented. This optional further incubation is not intended for routine
use but may be used for special studies.
In the case of a positive control BI, a yellow color change of the growth media will appear
within 24hours. Any observation of a yellow color within the vial indicates a positive
result. The pH color change result can be recorded and the BI discarded as soon as the
yellow color is observed and the resultrecorded.
For processed 3M™ Attest™ Rapid Readout Biological Indicators 1295, the use of a
humidified incubator is recommended to avoid media dry out. If a visual pH color change
result is desired, transfer the processed 1295BI to a humidified incubator after the
fluorescent result has been determined in the 3M™ Attest™ Auto‑reader 490H. A media
color change from purple to yellow indicates a sterilization process failure. A negative pH
color change result, i.e., media remains purple, can be assessed at 7days.
INSTRUCTIONS FOR USE –DISPOSAL
Instrument contains a lithium battery. Dispose of instrument in accordance with federal,
state, and localrequirements.
FEATURES OF THE 3M™ ATTEST™ AUTO‑READER490H
Audible Alarm
An audible alarm will sound, the LCD display backlight will flash, and a (+) symbol will
be displayed on the LCD panel directly under the incubating BI when a positive result is
detected. An alarm will also sound if a 3M™ Attest™ Rapid Readout Biological Indicator
is removed from the 3M™ Attest™ Auto‑reader 490H well before a final result has been
detected. Data will be lost if the 3M™ Attest™ Rapid Readout Biological Indicator is not
replaced in the incubation well within 10seconds.
AlarmOn/Off
The audible alarm for positive results can be turned off for a particular 3M™ Attest™
Rapid Readout Biological Indicator. This is accomplished by pressing the “Buzzer Alarm
OFF” button after the alarm has sounded. This will turn off the alarm for that BI only. Any
positive 3M™ Attest™ Rapid Readout Biological Indicator results subsequently detected
in other wells will result in the alarm sounding. Removing the 3M™ Attest™ Rapid
Readout Biological Indicator will reactivate the alarm for that well. Pressing the “Buzzer
Alarm OFF” button will not silence the alarm for error or caution code alarm warnings. To
disable the alarm, see configurationsection.
Stackable
To save counter space, 3M™ Attest™ Auto‑readers 490Hs may be stacked twohigh.
InformationButton
When the Information button is pressed once the 3M™ Attest™ Auto‑reader 490H
displays two lines of text in the LCDdisplay.
The top row indicates (left toright):
• 3M™ Attest™ Auto‑reader 490H serialnumber
• 3M™ Attest™ Auto‑reader 490H embedded software version (VX.Y.Z)
• Current date andtime.
The bottom row indicates (left toright):
• The BI type configuration for wells 1‑5(i.e.,1295)
• The BI type configuration for wells 6‑10(i.e.,1295)
Press the information button twice and the 3M™ Attest™ Auto‑reader 490H LCD display
will present two additional lines oftext.
The top rowindicates:
• IP address (if unit is connected to an Ethernetjack).
The bottom row indicates (left toright):
• Date (YYYY‑MM‑DD) and time that power was supplied to the 3M™ Attest™
Auto‑reader490H.
Press the information button three times and the 3M™ Attest™ Auto‑reader 490H LCD
display will present the unique Media Access Control (MAC) Address for thedevice.
TemperatureMonitoring
The 3M™ Attest™ Auto‑reader 490H contains an internal temperature self‑diagnostic
program. Should the temperature fall outside the specified range (60ºC +/‑2ºC) an error
code will be displayed. The heater block temperature may be checked by depressing the
Temperature buttononce.
EasyConfiguration
The 3M™ Attest™ Auto‑reader 490H may be configured using either the buttons located
on the front of the unit or using the optional 3M™ Attest™ Auto‑reader 490H Web App.
Optional 3M™ Attest™ Auto‑reader 490H Web App
If desired, the 3M™ Attest™ Auto‑reader 490H may be connected to a PC via an Ethernet
connection for additionalcapabilities:
• Remotely view current status of BIs in the 3M™ Attest™ Auto-reader 490H via
networked PC or mobile hand held devices. For full functionality, the use of an HTML5
compliant browser with JavaScript enabled is required.
• Remotely view and configure 3M™ Attest™ Auto‑reader 490Hsettings.
• View the last 100BIrecords.
• Print out documentation using a local or networked printer and/or save documentation
as an electronicfile.*
Note: To access the 3M™ Attest™ Auto‑reader 490H Web App within a secure network,
the PC or mobile device must have access to the secure network; options include
connecting via a network Ethernet cable, signing in to the facility’s wireless network, or
connecting via a virtual private network(VPN).
