Since noone answered this, I'll take a shot. Set the ASA in the top window
using the top slider. The left position is full-power manual with an ASA 100
guide number of 20 (metric). The f#-distance combo in the paired scales are
used. Find your subject distance, and set the matching f# on the lens. This
position is also for TTL control by the camera, but the OM-10 does not do
that. The other positions are auto flash controlled by a sensor in the O of
"Olympus" on the front. Select one and set the lens to the f# above its
mark. The matching distance is the probable maximum usable distance. The
ready light voltage of the flash will set the OM-10 to the shutter sync
speed. For other flashes without a compatible pin, you will have to set the
mode control to manual, and, if you have a manual adapter, set a 1/30s or
slower shutter speed on it.
