Features 

 

Audible Alarm 

 
An audible alarm will sound and the positive  
red (+) light will illuminate for the designated 
incubation/reader well when a positive result is 
detected. This provides results in the least amount 
of time without the need to manually take frequent 
readings. An alarm will also sound if a RRBI is 
removed from the Attest 290 Auto-reader well 
before a final result has been detected. Data will be 
lost if the RRBI is not replaced in the 
reader/incubation well within 10 seconds. 

 
Alarm On/Off  

 
The audible alarm for positive results can be turned 
off or on for a particular RRBI. This is 
accomplished by pressing the "alarm off" button 
after the alarm has sounded. This will turn off the 
alarm for that RRBI only. Any positive RRBI 
results detected in other wells will result in the 
alarm sounding. Removing the RRBI will reactivate 
the alarm for that well. Pressing the “alarm off” 
button will not silence the alarm for error or caution 
code alarm warnings. 
 
To turn alarm function off (disable), press both the 
"alarm off" and "time remaining" buttons at the 
same time. A yellow period will appear on the lower 
right corner of the display panel to indicate the 
alarm is disabled. The alarm will be disabled for all 
positive RRBIs, error codes, and caution code alarm 
warnings. 

To turn the alarm function back on, press the "alarm 
off" and "time remaining" buttons at the same time. 
The yellow period on the display panel will turn off, 
indicating that the alarm is again active.   
 

Time Remaining 

 
When the “time remaining” button is pressed, the 
incubation time remaining for each individual 
incubation/reader well that contains a RRBI will be 
displayed. All three lights for each individual 
incubation/reader well will illuminate as the time 
remaining is displayed. The process begins with the 
incubation/reader well containing a RRBI on the left 
and proceeds to the right.  The time remaining 
appears in hours until there is less than an hour 
remaining when it displays minutes remaining. 
 

Temperature Monitoring 

 
The Attest 290 Auto-reader contains an internal 
temperature self-diagnostic program. Should the 
temperature fall outside the specified range (60ºC 
+/-2ºC) an error code will be displayed. 
 

Power Cord Retaining Clip 

 
Place the power cord through the power cord-
retaining clip on the rear of the Attest 290 Auto-
reader near the plug in.  This will help to ensure that 
the power connection does not become 
inadvertently disconnected. 
 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Care and Cleaning 

 
  
 

Clean the exterior surface of the Attest 290 Auto-
reader, with the dust cover closed, by wiping it with 
a damp cloth moistened with a mild detergent.  Do 
not open the dust cover and attempt to clean interior 
components.  If additional cleaning of the wells is 
required, call for repair or replacement.   
 

Note:

 The Attest 290 Auto-reader does not contain 

any user serviceable parts or require any routine 
maintenance. Any malfunctions will be indicated by 
an error code. Refer to the Trouble Shooting Guide 
section for error code explanations.
