Presets 

The DP564 stores up to 32 presets. Each preset includes all active settings. If you 
recall a preset, then change one parameter, the configuration with the one changed 
parameter is not stored unless you save it as a separate preset. Presets 29–32 are 
reserved by the factory configurations shown in Table 4-2.  

Note:

  The factory ships the DP564 with these same presets saved as presets 1–4, 

respectively, so initially you can apply these presets by pressing the front-
panel 

Preset

 buttons. Presets 1–4 can be reset, of course, to suit your 

requirements.
