Okay...Success!
Changing subwoofer software from v1.25 to v1.23 worked.
Here’s the process
Download the program STM32 and get the software ZIP file from Perlisten and follow the steps, just need a USB cable to update.
Perlisten D12 03-00 Error Code
Hello,
Wondering if any Perlisten D Series subwoofer owners have encountered this error code before "03-00". Subwoofer won't work at all. Turned it on and off multiple times to no avail.
Sent an email to Perlisten and waiting.
Sadly subs are brand new, other one is fine.
Thanks
