The controller will provide security for the following menus and functions,
if the Access Code is enabled, by prompting for a 4-digit numeric access
code:
• Configuration/Calibration Menu
• Profile Edit Menu
• Manual Override during a run
• Start of a run on second or subsequent step in a profile
• Manual change in Run profile execution to a prior or following step
• Premature termination of a profile run
If access code protection is enabled (see the Configuration/Calibration
section), access to the above functions is gained by entering the access code
as follows:
1. Use the Enter and the Back key to select the desired digit. Use the up
or down arrow keys to change the digit. When finished, use Enter to
confirm entry of the code and to move into the selected protected
function or menu.
2. The access code when protection is disabled is 0 0 0 0.
3. The access code can be enabled, changed, or disabled by using
“Change Access Code” (see Configuration/Calibration section).
1. Load the product into the freezing chamber. On IVF models, make
