CAUTION
: Take care not to insert the batteries in the wrong
direction, as this may cause permanent damage to the unit’s
internal electronics.
When the batteries are inserted correctly, the unit will automatically
turn on and enter the clock set-up mode. (see section
3.8
).

Turning the Luminometer On and Off
To turn the unit on, press the button. The unit
will beep once and display the power-up self-
check screen:
NOTE
: If the batteries are too low, the unit may
turn on and back off again automatically, or may
not turn on at all. If this happens, replace the
batteries immediately.
The unit will then perform an internal 15 second
calibration (see section
2.7
).
NOTE
: If the clock is not set, the unit will automatically enter the
time and date set-up mode (see section
3.8
) before performing its
calibration.
TIP
: It is recommended you synchronize the unit after changing the
batteries before use. This will allow SureTrend software to set the
date, time, and format to the computer’s date, time, and format.
TIP
: To activate the backlight features press and hold down the
button. The backlight uses more power and will drain the battery
faster.
To turn the luminometer off, press the button. The luminometer
will beep once and the display will go blank.
NOTE
: To avoid accidental turn off, the button is disabled when
the luminometer is performing a sample measurement.
