(error code: K6706)
• When a device number to be initialized exceeds “32767” (error code: K6706)
In this case, devices up to R32767 (ER32767) are initialized.
• When the protect switch of the memory cassette is set to ON (error code: K6770)
• When a memory cassette is not connected (error code: K6771)
