How do i enter the code.
once i enter in the four digit
code do i have to push enter or another
button.

I don't know what i did but now i have
"wait" displayed on my screen.

I don't know but i may have the wrong
code.

 

After you have correctly entered your 4 digit code press the signal seek switch, it's the rocker switch on the far right, or to the right of the "0"
