Turning off the Display
The unit is not equipped with the power button.
The display always appears on the window,
which almost will not influence the battery life.
To turn off the display, slide the HOLD switch in
the direction of the arrow in the stop mode.
“HOLD” will flash for three seconds and then the
display turns off in the window. To turn on the
display, slide the HOLD switch in the opposite
direction.
