Numeric Keypad
The Numeric Keypad is used to input speed, time, and temperature
values into the HOME screen and to select the advanced features. The
ENTER key enters newly inputted speed, time, temperature, and RCF
values into memory; it also allows you to bypass options in the
OPTIONS sequence without selecting or deselecting them. The
CLEAR key sets a blinking value to zero in the SET display, clears
entry errors or fault messages, and if the barcoding accessory is used
and the door is open, deletes barcode data input after the last run was
completed (keypad lock must be set to FULL FUNCTION). The +/–
key is used to toggle between positive (+) and negative (–) temperature
values.
