head unit install

just installed pioneer p4900ib in my truckafter you turn the ignition off and the head unit goes off

it beeps a bunch then stops

what does this mean?

is something wrong?
nothings wrong..

it's called a warning tone.. it will do it everytime you turn ur ign. off... you can turn off the worning tone buy turning off the radio. press and hold function button and go threw the menu till you see it.. then turn it off..
