Display saving function
This function is provided to extend the service life of the
LCD monitor. It starts up if none of the front panel
controls have been operated or the cassette tape has not
been run at all for about 5 minutes.
While the saving function is working, the LCD monitor
display goes blank, and the “EX” symbol appears on the
time code display area.
To release the saving function, operate a button or dial
on the front panel or issue a tape transport command
from the controller. The operation performed to release
the function will be executed after the function is
released.
