3. After confirmation, Release the TEST code (R/C code

47H), display will return to EE mode.

1. During EE mode, send the TEST Code (R/C code 47H)

to VCR and hold the Test code, do not let go.

2. While sending the TEST code, the monitor screen will

display the initial JP and Y/C Rec Current setting,
Video mode and ROM Version condition.
