Use a screw driver to tighten the attachment screws and secure the GP unit in
place.
A torque of only 0.5~0.6 N•m is required to tighten an attachment screw.
Be careful not to use too much force, since it may damage the GP unit.
Insert each of the fasteners into its slot as shown below. Be sure to pull the fas-
tener back until it is flush with the rear of the attachment hole.
