Power Fail Detect:
If the power were to fail for any reason while heating, the
control will retain, in memory, the programmed operating
conditions. When power is restored, the control will

the key will display the amount of time that the power
has been off. The control will stop counting the amount
of time the power has been off when it has been off for
more than 24 hours.
NOTE: If such an event has occurred, it is strongly
recommended that you ensure the food is safe for
consumption according to local health regulations.
Display High/Low Probe Temperatures:
To observe the recorded maximum or minimum probe
temperature when cooking by probe, press the following
keys while the probe remains in the product:
Highest Temperature: Press p

Probe Usage:
When the oven probe remains inserted in the probe
bracket, the LED temperature display will indicate the
ambient air temperature inside the oven. To use the
probe for cooking remove it from the bracket and wipe
the full length of the metal probe with a disposable
alcohol pad to clean and sanitize before using.
Only the tip of the probe senses the internal product
temperature; therefore, it is important the tip be placed
correctly in the product for internal temperature accuracy.
Push the probe tip halfway into the product, positioning
the tip at the center of the food mass. When inserting
the probe into solid foods such as meat roast or poultry
breasts, push the probe in from a straight downward
position or in from the side to the center position. If
placing into a semi-liquid or liquid product, the probe
cable must be secured to keep the probe positioned
properly. Do not let the probe tip touch the edges,
bottom or side of a container. Tape the probe cable to the
lip or edge of the container.
Probe Calibration:
1. To verify product probe calibration, place the
probe in a warm glass of water along with a
quality independent digital thermometer and
press the probe key for two (2) seconds to
display the probes actual temperature. Compare
readings.
2. If calibration is required, press the probe key
for eight (8) seconds until the unit beeps twice
and the probe offset is displayed. Adjust the
probe offset to match the difference between the
independent probe temperature and the control
probe temperature by pressing the up or down
arrows to increase or decrease the offset.
3. Repeat steps 1 and 2 to verify the probe
calibration as necessary.
OPERATING FEATURES & FUNCTIONS
NOTE: When cooking by probe, insert the probe
into the raw product after the oven has been
preheated.
WAIT ONE FULL MINUTE to allow the probe
temperature to decrease to the internal temperature
of the product. Press the start button to begin
the cooking process after this probe temperature
adjustment period. A false probe reading of the
internal product temperature will cause the oven to
default to a holding temperature.
