backlight intensity previously set, she/he only needs to push the button to the left of

seconds, the
MARLEY
automatically reverts to its “idle” status without changing the
display backlight intensity.

it is necessary to push the encoder seven times in balanced mode or eight times in
dual single-ended mode: the firmware revision is then displayed as shown in Figure
