• Operation of TR JUMPs other than 100TR is continued after your finger has left the key.
CRG Move and 100TR Jump are forced to the Tracking Close Mode when the key is released.
• Powering on or off resets the Jump Mode to the Single TR (91).
• When ACC or Back up is off, the test mode is canceled.
Note: The H-BUS head unit must be employed for controlling the test mode.
Note: Sound is unavailable even after the tracking has been closed
(this trouble results when the IC for the STS is not controlled in the test mode).
Note: When you pressed the [FF] or [REV] key during the Focus Search, you must turn the power off immediately
(otherwise, the lens can stick resulting in actuator damages).
Important: For continued key operations, keep the interval between key operations 4 seconds or more.
