Start

The START pad begins any function. If non-sensor cooking is 
interrupted, touching START will resume the preset cycle. 
Touching START will not resume an interrupted sensor cycle.

JET START™ Feature

The JET START control (START pad) automatically starts the 
microwave oven at 100% power for 30 seconds, and adds 
30 seconds of cook time, up to 3 minutes, then 1 minute of cook 
time, up to 10 minutes with each additional touch of the control.

Time may be added in 30-second increments to any manual 
cooking cycle, at the current power level, by touching the 
JET START control during cooking.

Off-Cancel

The OFF-CANCEL pad clears any incorrect command and 
cancels any program during cooking. It will not erase the time of 
day. OFF-CANCEL is also used to lock and unlock the control 
panel. See “Control Lock” section.

The microwave oven will also turn off when the door is opened. 
Close the door and touch START to resume the non-sensor 
cycle.
