To switch System Protect on
1 Step through the Set Up menu to the System Protect menu page.
2 Use the left and centre knobs to set a password of 12 characters (including blank spaces)
made up of letters, numbers and a limited number of 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.
3 Turn the right-hand knob (‘on>’) clockwise to accept the password and switch protection on.
4 Press HOME to apply the System Protect state.
The Home page now indicates the unit is locked with inputs editable. The System Protect state is
retained after power down, as will be shown on the Home page when the unit is powered up again.
To switch System Protect off
1 Step through the Set Up menu to the System Protect page.
2 Use 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.
3 Turn the right-hand knob clockwise to apply the password.
4 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.
If accepted, the password cursor stops flashing. When you next access this menu page,
System Protect will be in the default Off state.
7.4. LCD Lighting (Page 4)
If required, the lighting of the alphanumeric display can
be adjusted to accommodate off-axis viewing.
To adjust the lighting
Step to the LCD page, and turn the left knob to adjust the display contrast. The default
setting is 5, with a range of 0-10.
7.5. Naming (Pages 5 and 6)
To help with system identification, the DN9848 unit and
the current working memory may each be given a name
up to 24 characters long.
Both names are shown in the Home page and are
retained after power down, which is particularly useful
for system reassembly when changing venues.
To enter a name
Use the left-hand knob to move the cursor right or left, and the centre knob to select the
letter, number or symbol. The name is automatically applied.
