INSTRUCTIONS FOR USE – 3M™ Attest™
Auto‑reader 390G Configuration
Note: Ideally, the 3M™ Attest™ Auto‑reader 390G should be empty (i.e., have no incubating BIs) when it is reconfigured.
Press the 
and 
buttons on the front of the 3M™ Attest™ Auto‑reader 390G simultaneously for 3 seconds to enter configuration mode. Once in configuration mode,
use the Up 
and 
Down buttons to set the 3M™ Attest™ Auto‑reader 390G
clock and audible alarm as desired. The 
button acts as an “Enter” key and moves the flashing cursor to the next changeable setting.
Setting the 3M™ Attest™ Auto‑reader 390G Clock
The 3M™ Attest™ Auto‑reader 390G date and time are displayed in this format:
YYYY‑MM‑DD HH:MM, with the time displayed using a 24 hour clock. To change the year,
if necessary, push the up or down buttons to set desired year, then press 
to advance
to the month, adjust as necessary and press 
to advance to the day. Use the 
button to move to the time and set the hours and minutes.
Setting the Audible Alarm Function
Move across the top row of text by pushing the button. The flashing “B” in Buzzer indicates this is a changeable setting. It is recommended this be set at “Buzzer Enabled” to audibly alert the operator to a positive BI but it may be set to “Buzzer Disabled” by using either the up or down button. Note: If Buzzer Disabled is selected, and the changes accepted, the speaker icon ( 
) will disappear from the LCD panel and the alarm will be disabled for all positive 3M™ Attest™ Rapid Readout Biological Indicators, error codes, and caution code alarm warnings. Note: The 3M™ Attest™ Auto‑reader 390G display backlight flashes whenever an audible alarm sounds. Disabling the audible alarm does NOT disable the LCD display backlight flashing.
Press 
to select the desired option and advance to the Accept screen.
Accept Screen
Use the up or down buttons to toggle between Yes and No, press to accept changes (Yes selected) or retain current settings (No selected) and exit the configuration mode. The LCD panel will return to the standard display.
