Security and other Set Up Options

To set a Panel Lock

1Step through the Set Up menu to the Panel Lock menu page.

2Use the left and centre knobs to set a password of 12 characters, including blank spaces, made up of letters, numbers and/or symbols.

Important! Note that preliminary and subsequent blank spaces are recorded as part of the 12-character password; therefore if you use a short password, the characters must be re- entered in exactly the same position to unlock the panel. To avoid confusion, either record the blanks as part of the password or enter the word at the far left of the display.

3Turn the right-hand knob clockwise to cycle to the required lock type.

4Press HOME to apply the Panel Lock.

The Home page now indicates that the unit is ‘Locked’. The lock state is retained after power down, and will be indicated on the Home page when the unit is powered up again.

To remove the Panel Lock

1Step through the Set Up menu to the Panel Lock page.

2Use the left and centre knobs to enter the password. Note that the letters must be in the same position as when the password was set.

3Turn the right-hand knob clockwise to apply the password.

4If correct, the display will report ‘UNLOCKED’. Press HOME to exit the page and return to normal operation.

If you have entered the wrong password, the DN9848 will flag it as incorrect and return to the Panel Unlock page for a further attempt.

7.3.2System Protect (Page 3)

System Protect offers limited operational control while protecting against unauthorised users tampering with key parameters that may result in loudspeaker damage.

When System Protect is on

The output MENU ACCESS buttons and Output Mute controls are disabled, but the inputs can still be edited.

User memory settings can be recalled or stored, but factory and system memories are inaccessible.

The full Set Up menu is still available.

Note Panel Lockout takes priority over the System Protect state.
