[Kenwood] Turning on and off "bug" as keying device

[John King]

I have a Vibroplex keying mechanism that can be used like a BUG or Iambic key. I have the menu up  and 35 as the menu item displayed. The menu shows "OFF" and I need to switch it to on. I must be senile, but I can't find the button to turn the Iambic keyer  to  "on" from "off". Can someone please tell me how to turn it to "ON" ??? Thanks, John, K5PGW
