Optic S1 Secondary Unit Setting
In M manual flash mode, press <S1/S2> button so that this flash can function as an optic
S1 secondary flash with optic sensor. With this function, the flash will fire synchronously
when the main flash fires, the same effect as that by the use of radio triggers. This helps
create multiple lighting effects.
Optic S2 Secondary Unit Setting
Press <S1/S2> button so that this flash can also function as an optic S2 secondary flash
with optic sensor in M manual flash mode. This is useful when cameras have pre-flash
function. With this function the flash will ignore a single “preflash” from the main flash
and will only fire in response to the second, actual flash from the main unit.

S1 and S2 optic triggering is only available in M manual
