7.7. LCD contrast adjustment (Page 6)
To ensure optimum screen visibility in a range of lighting conditions, it is possible to individually
adjust the contrast of the two LCD displays.
• “Alpha” adjusts the contrast of the alphanumeric display
• “Graphic” adjusts the contrast of the large graphic display
• “INV” allows the mode of the graphic LCD to be switched between white-on-blue to blue-on-
white.
7.8. Naming (Pages 7 and 8)
To help with system identification, the DN9340E unit and the current working memory may each be
given a name up to 20 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
1
Use the left control knob to move the cursor right or left, and the centre control knob to
select the letter, number or symbol. (
Tip: to clear existing characters enter a blank space
which can be found after the letter Z.)
2
Press
HOME (SETUP)
to apply the new name.
All names are stored with System memory settings. The Store function will assume the working
memory name as the default memory name, prompting you to edit it if required (see Section 8
Storing and Recalling Settings).
7.9. Delay options (Page 9)
The units of measurement used to specify the delay settings can be set to suit user preference, as
follows:
• Time (milliseconds and microseconds)
• Metric distance (metres)
• Imperial distance (feet and inches)
To change the units of measurement
1
Turn the left control knob to choose the units.
2
For Metric or Imperial distance measurement, specify the ambient temperature of the venue
using the centre control knob. The DN9340E will use this to adjust the speed of sound (which
varies with temperature) in the delay calculation so that accurate delays are applied to the
channels.
The delay units are changed in the input and output menus, with the current values being
automatically converted to equivalent values.
