7200 Monitor Instruction Manual

19 Instrument Security

The 7200 Monitor can be locked to prevent unauthorised access to the configuration menu’s by using a password. The
user password is a 4 digit number that can be set to any value the user chooses. When supplied new, the user
password is set to 1000, we recommend that this is changed when the instrument is installed.

Note: The factory default password is 1000, if the original password has been forgotten please contact
Partech technical support.

19.1 Lock Instrument

To lock the instrument, this menu is used. The user will be prompted for the entry of the user password, when entered
correctly the instrument will be locked. The instrument can only be locked with the correct user password thus avoiding
accidental/unauthorised locking.

19.2 Change Password

The method of changing the user password is described in the instrument configuration section of this manual.
