Child Protection
If the door is opened repeatedly when a program is running, the child protection function will
engage automatically. The first time the door is opened, the motor will still be running for a
short time. The door will be unlocked for a shot time when operation is resumed; if the door is
opened during this time, the machine will shut off automatically.
Child Lock
The child lock function can be set to prevent children from operating the machine when a
cycle is in progress, locking the door and the control panel (except for the power button).
Power on the machine, then press and hold the "TEMP". button for 3 seconds until the
buzzer sounds. The child lock function is now set. If these steps are repeated, the child lock
function will be disengaged. When this function is disabled, the door can be opened again.
