e. Slide the left or right side of the back-bar into the wall as shown in
Figure 8

f.
Center the mounting bracket in the wall and tighten the screws until the bracket is firmly held in the wall.
Over tightening will distort the bracket and prevent the Keypad from snapping tight against the wall.
Under tightening will cause the Keypad to be loose against the wall.
g. If there is not enough room to slide the keypad in as described above, you can hold the back-bar in
place as you run the screws through the mounting plate and into the back-bar. TIE A LONG STRING
TO THE BACK-BAR so that you can easily retrieve it in case you drop the back-bar into the wall!
