Sea & Sea YS-01 only working in TTL mode ?

Have 2 YS-01, both only work in ttl mode. This on a Olympus TG4 in an Ikelite housing and a Panasonic LX7 in a Nauticam housing.

Neither manual modes work. With the Panasonic, the strobes do not fire at all in either manual mode. With the Olympus, the strobes fire in manual, but the sync timing is off and the pictures are dark.

Strobes work with both cameras in TTL and I can micro adjust in TTL. Any ideas ?

try what it says here

however the LX7 is different if sync is off is typically because of preflash so camera flash to manual and strobe try with and without preflash (should be without)

Never realized there were more flash options.

I tried the various options on the TG4 and strobe, but still no go. The strobe fires in all modes, but does not sync with the camera shutter in either strobe manual mode. TTL works.

On the LX7 change the sync to type 2, whatever that means. Now the strobe fires and works in manual.

Looking forward to having full manual control on the LX7. Will use TG4 in TTL but also want to try TG4 macro with a video light.

Thanks big time.
