smoking; greasy spillovers may catch
on fire.
■It is safe to place hot cookware
from the oven or surface units on the
glass-ceramic surface when it is cool.
NOTE: Cooktop temperatures increase with the
number of surface units that are on. With 3 or
more units turned on, surface temperatures are
high, so be careful when touching the cooktop.
The hot surface indicator light(s) will remain lit
after the surface unit is off until the surface has
cooled below 150°F.

Precise Warm Feature
To turn on the precise warm feature:
Touch the ON/OFF pad, then
touch the PRECISE WARM pad.
The surface unit will turn on to
warmer setting W3 (medium setting).
Use the (+)/(–) pad to choose
additional settings between
W1 (lowest setting) and W5
(highest setting).
To change from the warmer settings
to regular cooking settings, press the
PRECISE WARM pad again. The surface
unit will be on power setting LO. The
surface unit may then be set to the
desired regular cooking setting using the
(+)/(–) pads. To turn off the surface unit,
whether using regular cooking settings or
warmer settings, touch the ON/OFF pad.

The chart above shows initial suggested settings only.
The temperature, type and amount of food, type of pan
and the time held will affect the quality of the food.
CAUTION: Do not warm food on a
PRECISE WARM surface unit setting for more
than 2 hours.
Do not use plastic wrap to cover food. Plastic
may melt onto the surface and be very difficult
to remove.
Use only cookware recommended for
top-of-range cooking.
CAUTION: Always start with
hot food. Do not use to heat cold food.
Placing uncooked or cold food on a
precise warm setting could result in
foodborne illness.
For best results, all food on PRECISE
WARM should be covered with a lid or
aluminum foil.
Always use pot holders or oven mitts
when removing food from a precise warm
surface unit as cookware will be hot.
A hot surface indicator light will glow
when the glass surface is hot and will
remain on until the surface has cooled
below 150°F.
All single burners may be used for
either regular cooking or precise
warming.
Dual Surface Unit Control Knob (on some models)
The right front surface unit has 2 cooking sizes
to select from so you can match the size of the
unit to the size of the cookware you are using.
To use the small (6″) surface unit, turn
the control knob to the SMALL BURNER
settings.
To use the large (9″) surface unit, turn
the control knob to the LARGE BURNER
settings.
