Note that the temporal amount of audio signals that can be recorded on one track of the magnetic disk 25, that is, the recordable time, is limited, so when recording, please press the recording button 6 or 7 before pressing the recording button 6 or 7. Then, the recording time display button 17 may be operated to display the elapsed recording time on the display 9, and then audio capture may be started. If the necessary audio has been captured before the predetermined recordable time has elapsed, if the recording button 6 or 7 is released from the recording button 6 or 7 when the recordable time has elapsed, the necessary audio can be captured. is recorded, and recording can be performed while effectively using all of one track. Also, if the necessary audio has not been captured even after the recordable time has elapsed, continue to press the recording button 6 or 7,
If the press of the recording button is released when the necessary audio has been captured, the audio captured after the recordable time has elapsed since the release will be recorded.

Furthermore, if you want to record at the same time as shooting, you will need to operate the shutter release button 5 and the recording button 6 or 7 separately. Push in and
By releasing the recording button 6 or 7 a little after the shutter release, it is possible to record audio at times before and after the shooting time.

If you want to know the remaining number of tracks that can be photographed or the number of tracks that can be recorded, you can display the remaining amount of tracks by operating the track button.
