DM-3200 Battery Replacement (DM-4800 too)

[traceoflife]

I wanted to post this for a few reasons.
A. Seemed some other forum was the resource and we can't have that
B. Because the battery can be the source for random errors leading you to think your device is crapping out.
Mine was throwing SRAM errors on boot, until the battery finally failed. I should not have put it off for so long and just done the replacement.


Battery for the DM-3200/4800 is regular CR2032 3v. Follow the below instructions to replace it.

Opening the mixer:

- Unscrew the "wood" sides (8 screws in total, 4 per side)


- Remove the upper grille strip, it should come off easily, it is held in place by its own tension.


- Remove the metal strip above faders, this one should come off easily too, no screws here either. It is metal and can be pried up easily with a small screwdriver


- Remove 4 screws from upper part of the main panel (where grille used to be)


- Remove 4 screws from lower part (where the metal strip used to be)

-Remove a screw on each side (2) in the center holding the main LCD area in place.



- The main panel should now be free and it can opened. The panel is hinged from the lower side, it should open up simply by pulling from the upper edge. All the cables should have enough slack so that the panel can sit upright.


The battery clip is located in a bit tricky place, look under mic pre section, to the back right corner and you should see it there.
If you want you can also remove the mic pre section but that a bit more work. It was easy to remove by sliding it out from the left side. Same goes for sliding the new one in.


Now all that is left is to reassemble it in reverse order.
Cheers.

You also have to remove the 2 screws on the card reader slot.

About the DM4800, it is easier to remove the top of the mixer, (where the XLR and jacks are), there is 6 screws (3 on each side) and 7 on the rear. Fortunatly, the battery is not welded.

Peripheral to this discussion (non-Tascam equipment):
It would appear that on onboard 2032 battery is a very popular design feature in gear that needs to retain info/settings when powered off/unplugged.
I’ve found this in countless pieces of gear - usually when the 2032 has croaked, with a variety of impacts on said piece of gear.

So I’ve also learned that often, replacing can restore capabilities and/or functionality. I’ve done this to at least a dozen pieces of gear, including ones where a “tabbed” 2032 was soldered on one of the PCB’s (can you say “cost-saving design”, or “planned obsolescence”???).
Typically I’d remove the soldered-on batt’y, and replace it w that little plastic socket, so the batt’y can be easily changed.

In this thread, I describe how I purchased a piece of gear worth hundreds for less than 5 bux, ‘cuz someone had dumped it (non-functioning) on a thrift store, unaware of this 2032 issue.
I fixed it for less than a dollar!
