If your chosen security code is not entered within 20 seconds the unit go in to 'lockout' and your security code will
not be saved. To restart, turn the security key off and on, and then re-enter using the original security sequence.
Pressing the treatment button will cause the unit to go in to 'lockout' and will not save the password.
