Thanks all for your replies!
Originally posted by phoenixvision first of all make sure the back side of the flash, the plastic light has direct vision with your camera, this simple step I missed when I first used it....then if you just use the info screen, rather than going to menu, and use the arrow pointing down it will take you to the four flash chices, of which you want to choose wireless remote, make sure the flash is on slave....and the camera flash is up.....this should work, let me know what happens....
@Phoenixvision, I followed all these steps. The flash is in wireless slave mode . Interesting note: whenever I half-press the shutter and metering is on, the the slave mode disappears from the flash screen and It automatically sets itself to a focal length of 16mm and blinks. Whenever metering stops, it returns to where it was before.
I tried accessing the wireless mode as you mentioned, but cannot find it in under the "info" menu, only main camera settings there (ISO limits, file format, ...). When I try to access it under the flash menu on the K-3 screen (bottom key on the 4-way controller), the wireless option is greyed-out and not selectable.
