Menu Step
T-16 Do Total This step allows all programmable settings, all product settings, and all
Init statistics values to be initialized to factory preset values.
(The Activity Log, however, is not reset by this initialization, and in fact
will log a record of the "init" function itself.)
To totally initialize the controller – including all cook settings – back to
factory default values, press and hold the DOWN button for about 2
seconds.
Calibration data will not be affected by this initialization, unless values
are found to be outside of acceptable limits.
Description
Statistics values, the Error Log, Review Usage
data, etc., will be reset by this "total" initialization.
All of the operating history data will be lost. For this
reason, the normal "Init" step in Special Program
mode is generally recommended, unless one
specifically intends to completely reset all the
statistics data.
