Got a curious little episode: My DP-32 is plugged into a central AC supply that is shut down when the studio isn't in use (to prevent power surges/fluctuations - very common here). And yes, the DP is always properly shut down before the AC mains are powered down. Recently I started a new project and found that it was time-stamped wrong - the internal clock had reset itself to the default of 01-01-2000, 00:00:00AM. I immediately suspected that it might be the internal/backup battery (the one that maintains settings/preferences when the unit is powered down and/or unplugged from AC power)...especially 'cuz the Preference panel's setting for AutoPowerSave (which I leave [OFF]) had ALSO reset to [30MIN], which I believe is the default. BUT: all other system settings, preferences, etc are still in place - screen settings, footswitch choices, JumpBack, Undo levels, PeakHold/Preview time, yada. And of course the settings written into each project's "file" are intact. Any insight on this? If it IS the internal battery dying (probably one of those on-board 2032's) - does anyone know where it is/how hard it is to get to...or have any other guidance on replacing it?
