Good evening, to all forum users.
I recently bought NL2.When enabled, it returns an error in the form of L, L,L appearing on the display . After reading the forum, I found how to test variable resistors-I found out that 12 pieces do not work well .does this synthesizer have a test mode? How do I log in ?How to decipher error codes.Unfortunately, I didn't find a service manual for this synthesizer on the Internet.I will be grateful for any help.
