Photo Cell Settings
The VS-LCD features a smart photocell
which allows the flash unit to be
triggered by another flash or to be
triggered by a second or third flash to
allow for anti-red eye preflashes.
To Set the Photo Cell
Press the MODE button five times. The
display will read “Photo Cell” and the
current setting. Press the up/down
arrow buttons to adjust the setting to
OFF or one of three modes. When done,
press the ENTER button. An “eye” with a
small number will appear if one of three
autoflash settings is on. There will be no
“eye” if the photo cell is not active.
Photo Cell “1”
If you have selected “1” in the procedure
above, the unit will autoflash immediately
when another flash is activated in the
same area. The “eye” will show in the
display with a small number “1.”
Photo Cell “2” and “3”
If you have selected “2” in “To Set the
Photo Cell” above, the unit will autoflash
on the second flash the photo cell detects
and will ignore the anti-red eye flash,
also known as the “preflash.” If you have
selected “3” the unit will autoflash on the
third flash detected by the photo cell.
