not sure what u mean by the flashes and making it flash more but yeh ... in the menu ... scroll till the bottom LED flashes on its own ... press and hold the trigger and give it a sec and the bottom LED will flash. the number of times it flashes is the mode that it's in. 2 flashes for capped semi ... if its not on 2 flashes then after the LEDS have stopped flashing, pull the trigger twice and the LED should flash twice with your trigger pull .... wait for a couple secs then the bottom LED should start flashing again ... TADA ... marker is in semi-capped mode.
to change the ROF you need to do the above but the menu LED is the 1 from bottom LED and flashing .... count the number of flashes it does there and choose the 15.2 BPS cap ... can't remember how many flashes that is but its in the ego manual =)
hope that clears a few things out
