• Press the shutter release button halfway and make sure that
a shutter speed appears in the viewfiner.
Timer switch
The built-in timer switch automatically turns the meter off in about
ten seconds after you release your finger off the shutter button.
Battery check
If no shutter speed is displayed in the viewfinder even with a slight
pressure on the shutter button, the batteries have no power or may
be improperly inserted.
When batteries weaken
When the batteries are becoming weak, the shutter speed displayed
in the viewfinder starts to blink slowly at the speed of once per
second. If so, replace the batteries immediately. If the batteries are
completely exhaused, the shutter button does not release the
shutter.
