Hi. I am trying to test my alarm (G3). But when I enter the "PROG" and code (user), only the TAMPER led lights up (and not BOTH the TAMPER and DAY Leds as the manual says). . I`ve taken the panel off, entered code to silence panel, and reset and checked wiring). This resets to just DAY mode as expected. All looks ok. Any ideas why just this LED lights up on it`s own when testing? I cannot get passed this until I reset to DAY again.
