Important Information
This battery must be soldered directly to the circuit board inside the synthesizer.
If you are not experienced with soldering, we recommend leaving the replacement to a qualified technician.

• Avoid overheating the battery during installation — excessive heat may cause it to explode.
• Make quick solder joints and use a heatsink if possible.
• Battery replacement is a routine task for any service center and should be completed quickly.

⚠️ Before replacing the battery, be sure to back up all programs and sequences.
When the old battery is removed, the instrument will reset to factory settings and all custom data will be lost.
