ive never understood from the get go, what these really meant.

function 1 - arm. silent arm.
function 2 - arm. sensor bypass arm.
function 3 - arm. sensor silent alarm arm.
function 4 - arm. full silent arm.

so, #1 is silent arm. arms the alarm lights only, without the chirp. warns, and full alarm work as if it was armed regularly.

#4, full silent. warn/full alarm, never shown outside at the vehicle. no lights, no siren, only notification back to the remote. even the LED light, doens't stop a beat. as if nothing happened.

whats the difference between 2 and 3?

and its a clifford 50.7x. same as viper 5901.
