purposes only, and shall not be used for clinical or maintenance evaluations. Data shown 
in sample printouts and screens do not reflect actual patient names or testresults.
Hardware Disclaimer
The 3M™Attest™ Auto-reader390hardware specifications are subject to change. 
The system images, hardware components and hardware specifications included in 
the manual may not match the system installed. Any changes or modifications to the 
authorized system installation have been verified as compatible with the functionality

INDICATONS FORUSE
The 3M™Attest™ Auto-reader390is designed to incubate and automatically read 
the3M™Attest™ Rapid Readout Biological Indicators for Steam, 1291and 1292, at 60°C 
for a final fluorescent result at 1hour for 1291and 3hours for1292.
PRODUCTDESCRIPTION
The 3M™Attest™ Rapid Readout Biological Indicator System provides rapid, reliable 
monitoring of steam sterilization processes performed in health care facilities. The 
system is comprised of biological indicators, challenge packs, and an incubator/reader 
(3M™Attest™ Auto-reader390) with embeddedsoftware.
The 3M™Attest™ Auto-reader390is designed to incubate and automatically read 
3M™Attest™ 1291Rapid Readout Biological Indicators for Steam at 60°C for a final 
fluorescence result at 1hour and 3M™Attest™ 1292and 1292E Rapid Readout 
Biological Indicators for Steam at 60°C for a final fluorescence result at 3hours. The 
3M™Attest™ 1292E Rapid Readout Biological Indicator is not cleared for use in the 
UnitedStates.
The 3M™Attest™ Auto-reader390is also designed to allow for further incubation of 
3M™Attest™ Rapid Readout Biological Indicators for Steam, catalog numbers 1291and 
1292, for a final negative visual pH color change result at 24hours and 48hours, 
respectively. This further incubation is optional and not intended for routineuse.
A positive fluorescence reading or a visual pH color change indicates a steam sterilization 
process failure. However, due to the high sensitivity of the fluorescent result, there is no 
advantage to continuing to incubate processed 3M™Attest™ Rapid Readout Biological 
Indicators once the fluorescent result has beendocumented.
Other biological indicators (BIs) are not compatible with this device and cannot beused.
The unit is designed to be used only with the Power Supply module and Ethernet cable 
supplied by3M.
WARRANTY
The 3M™Attest™ Auto-reader390has a limited one year manufacturer’swarranty.
SerialNumber
For easy identification, each 3M™Attest™ Auto-reader390has a unique serial number 
printed on a label found on the back of the unit and displayed on the left side of the upper 
row of text on the LCD Display when the user depresses the   button. Please record 
your serial number in this manual for future reference:___________________.
