Checking the Battery
The main switch is also used for checking
the battery. To see if the battery power
level is sufficient, turn the main switch1
battery check lever to the "C" index on the
outer rim of the film rewind crank while
looking into the viewfinder. When the meter
needle rests above the battery check lower
border, which is indicated by the meter
needle position illustrated below, the power
level of the battery is sufficient. If the
meter needle just barely coincides with this
lower border, the battery is near exhaustion
and should be replaced. I f the meter needle
does not rise to the index, the battery must
be changed.
