7.8. Backup System (Page 9)
This menu allows you to backup the 32 System memories, as described in Section 8, into flash RAM.
By performing a backup, you can ensure that important System memories may be recovered in the
event of power loss and battery failure.
To backup the 32 System memories
1
Step through the Set Up
menu to the Backup
System page.
2
Turn the left, centre and
then right DATA ENTRY
control knobs clockwise
to accept the three
levels of confirmation.
Or, press the HOME button to
exit the operation and
return to the Home page.
The backup copies System
memories (S01 – S32) into
Backup locations (B01 – B32) in
one operation. You may recall
any of the backup memories (B01 – B32) using the Recall function as described in Section 8.
7.9. Delay Options (Page 10)
The units of measurement used to specify the delay on the input and output channels 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
Step through the Set Up menu to
the Backup System page.
2
Turn the left DATA ENTRY control
knob to choose the units.
3
For Metric or Imperial distance
measurement, specify the ambient
temperature of the venue using the
centre control knob. The DN9848E
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.
