Instrument Lockouts
The instrument can be configured to allow use only by authorized operators and/or to allow use only if
specified QC has been performed. If one or more of these lockouts is enabled, processing of the lockout(s)
occurs before any other instrument functions.

Prewarming
If the lockout checks are passed, a cuvette is automatically prewarmed to 37 °C ±1.0 °C when it is placed in the
test chamber. The instrument will sound one short beep when pre-warming is complete.

Test Timeout
Incubation of a cuvette stops automatically if START is not pressed within five minutes after Add Sample and
Press Start are displayed.

Automatic Shutdown
The instrument will automatically shut down after being idle for five minutes if there is no cuvette inserted in
the test chamber and the instrument is running on the battery.

Note: Results that are greater than the time noted in the package insert for a test are beyond the
sensitivity range of the test. They should be repeated immediately and, if confirmed, reported as
greater than the maximum sensitivity range.
