Oskar - Retra UWT

I understand you are trying to manipulate TTL mode into manual mode via TTL pre-flash. Pre-flashes in TTL are limited in power output (duration) and therefore it will not be possible to obtain the desired results. Unfortunately this is not a bug in the firmware but a part of the TTL protocol.

Apologies for the oversight—there was a typo. The accurate version is 4.5. Thanks for catching that; we'll make the necessary correction.

Hey Tim, good to know you got the new firmware update sorted. Just a heads-up, that flicker in the pilot light is totally normal, especially when LED is set to full power and in the 4xAA setup. If you switch to 8xAA, it becomes less noticeable, and sometimes, you won't even see it.

Which Retra Flash model? Sorry, just seen it's the first generation with single o-ring battery compartment and no leakage detection. Please send us any images to email/whatsapp/viber/imessage and we will do our best to assess the situation. For now just make sure the compartment will be dry so there is no additional corrosive action.

I wouldn't suggest using soap as it could contain chemicals that potentially speed up corrosion while trapped beneath the Bumpers. A very very small amount of silicon grease should suffice, to get the o-ring slightly shiny.
