Chevrolet blazer 2000 用户手册

The pegs inside the
compartment door are used
to make sure the button on
the compartment door will
contact the control button
on the garage door opener.

Add one peg at a time until the garage door opener
operates with the compartment door closed when you
press the button.

Now, with the compartment
door closed, press the
button again to make sure
the garage door opener
operates properly.

With the garage door opener positioned properly and the
right number of pegs in place, you should only have 
to press the button slightly to operate the opener. 
Adjust the position of the garage door opener and 
add or remove pegs, as needed, until the opener 
operates properly.
