The following buttons test mode functions do not depend on the test mode No.
[VCD Module condition check]
If the VCD module is in a good condition, the blue background appears on the monitor screen when in the CD test mode.
If the blue background does not appear, the possibility is that the VCD module has failed.
NOTE: None of the components of the VCD module can be supplied separately. Only a VCD module unit (VZ150200) is available.
When CD TEST MODE is set through SYSTEM TEST MODE, “00 TM1 0: 00” appears on the FL display.
