Optional Visual pH Color ChangeResult
3M™Attest™ 1294Rapid Readout Biological Indicators may be further incubated for
a visual pH color change. Due to the high sensitivity of the fluorescent result, there is no
advantage to incubating the 3M™Attest™ 1294Rapid Readout Biological Indicators
beyond 4hours. This optional further incubation is not intended for routine use but may
be used for special studies. A humidified incubator will be required to avoid media dry out.
In the case of a positive control BI, a yellow color change of the growth media will appear
within 7days. 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. In the case of a processed BI, a media color
change from blue‑green to yellow indicates a sterilization process failure. A negative pH
color change result, i.e., media remains blue‑green, can be assessed at 7days.
INSTRUCTIONS FOR USE –Disposal
Instrument contains a lithium battery. Dispose of instrument in accordance with federal,
state, and localrequirements.
FEATURES OF THE 3M™ATTEST™ AUTO‑READER390G
AudibleAlarm
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‑reader390G 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 10seconds.
AlarmOn/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 configurationsection.
Stackable
To save counter space, 3M™Attest™ Auto‑reader390Gs may be stacked twohigh.

Auto‑reader390G.
TemperatureMonitoring
The 3M™Attest™ Auto‑reader390G contains an internal temperature self‑diagnostic
program. Should the temperature fall outside the specified range (37ºC +/‑2ºC) an error
code will be displayed. The heater block temperature may be checked by depressing the
Temperature buttononce.
EasyConfiguration
The 3M™Attest™ Auto‑reader390G may be configured using either the buttons located
on the front of the unit or using the optional 3M™Attest™ Auto‑reader390G WebApp.
