FEATURES, CARE AND CLEANING
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.
