Displaying the same characters in the same positions on the screen causes
a LCD to degrade relatively quickly. To help prevent this, the screen can
be cleared by pressing specific keys. It is also possible to specify the
automatic clearing of the screen if no keys are pressed during a period
specified with a parameter.
But, the life of the back light may be contracted all the more when the
clearing of screen and re–indication of screen are repeated beyond the
necessity.
This effect can be expected when a screen is cleared for more than one
hour.
Holding down the
CAN
key and pressing an arbitrary function key clears
the screen.
Procedure for erase screen display
