Well I finally got the pictures sorry it took so long. The two jumpers on the front board are as followed. The jumper on the left has PPD and STD. When I changed it from STD to PPD it made the siren manual/horn only the rotary switch became disabled. The jumper in the middle has NINE and RADIO. When I changed it from RADIO to NYMR the radio became disabled, it allowed you to use the manual/horn while the rotary switch was on radio. (see photos below)
