Insert blanking plugs into screw holes in internal

Using the 4-way
locking system
Your PetSafe ® pet door is fi tted with the red 4-way locks on
the inside of your house.
The 4-way locks allow you to control your pet’s access in and out of
your home.
It is a good idea not to use the 4-way locks until your pet is thoroughly
familiar with using the door. Your pet may become confused as to why
you have installed it.
