Revo REHVDPTZ22-1 INSTRUCTION MANUAL - Manual (Page 10)

CAUTION: Before installing mounting bracket to surface pre-adjust the four mounting
screws "A" on the base of the dome camera to best match the mounting
bracket locked position. Unscrew the locking screw on the side of the dome's
base and fit the tab of the mounting bracket into the locking slot. Screws "A"
should not be too tight or too loose when the dome is in the locked position.
After setting the proper positions of screws "A" remove the mounting bracket
and install it to the proper surface. If it is too difficult to lock the dome in
position after the mounting bracket has been installed readjust the screws "A"
by unscrewing them a small amount and try to install dome camera again.
