Cygnus 2 Operating Manual
3.5.8 Lock and Access Codes
The Cygnus 2 has several forms of protection to prevent unauthorized changing of
parameters. Refer to the General setup section for a description of parameter and
Program lock codes and the File Access Code. In addition, a method of locking the
entire display is available through the remote communications. Lock codes are
entered on the General display. See
Chapter 6, General Parameters .
HINT: To clear any of the locks, except the File Access Code, hold down the
CLEAR key on power up. This will clear all lock codes. HOWEVER, if no
lock codes are present, all parameters will be cleared by doing this.
