Questions and answers
I have had DSP-256 for a long time. It just sent up a message, battery dead all saved data is lost. How do I change the battery, what battery number, and how do I change it
To change the battery in a DigiTech DSP-256XL:
1. Open the unit to access the internal battery.
2. The original battery is an Energizer 4.5V #523, which is obsolete.
3. Instead of searching for the original battery, you can replace it with a CR2032 (3V) coin cell using a standard holder.
4. Remove the existing battery holder from the board.
5. Install the new holder for the CR2032 battery.
6. Ensure a low leakage electrolytic capacitor replaces the original leaky tantalum capacitor.
7. Clean any flux residue from the board to prevent excess current leakage.
8. Verify the current draw with a microammeter if possible.
This setup provides enough voltage to retain memory when the unit is off.
