2）Host computer can only access function code of Group U0 after decryption(write correct factory password into
U0.00).If there is no communication for 5 minutes after acquiring access right,the right will disable automatically,and
it need to enter password again to access Group U0.
3）After acquiring the access right of Group U0,if host computer read U0.00,it will return 0000 instead of actual
factory password.
4）The operation of host computer and keypad to user password is independent. They need to enter the correct
password separately to acquire the access right.
5）Host computer has no right to modify factory password.When host computer write data into U0.00, it will
return invalid operation unless the data is correct password.
