CAUTION HOT indicator:
The caution hot indicator light warns that the temperature
of the air in the chamber is above 40°C (104°F). The
light will illuminate and remain lit when the temperature of the air in
the chamber reaches approximately 40°C (104°F). When the heat is
turned off, the caution hot indicator light will stay lit until the temperature
of the air in the chamber is less than 40°C (104°F).
3. Setting speed:
a. Press the up/down arrows below the speed display until you reach

light below the speed display will illuminate and blink until the
set-point is reached. Once the set-point is reached the light will
stop blinking and remain lit until shaking has ceased. The micro-
processor controlled ramping feature slowly increases speed until
the set-point is reached which helps to avoid splashing, and provides
excellent low end control.

will indicate zero (0:00). The unit time is now set to zero (0:00)
minutes. Alternately, you can use the up/down arrows to get to
zero (0:00).

indicate accumulated time. The up/down arrows will become inactive.

shaking when time display reaches zero (0:00). Four (4) audible
beeps will indicate the count down function is complete. The time
display will default back to the set time. To repeat for the same
time, simply press the on/off button again.
c. To interrupt an automatic timing cycle before it is completed, press
the on/off button below the time display. The display will flash off
