IMPORTANT:
 When the door of the cab is fully open, the door
appears in the image from left side camera (5). If the
field of vision is insufficient, ensure visibility using
the operator seat mirror.
 If there are any problems with the image on main
monitor (1), consult your authorized dealer.
 It may be necessary to reconfigure the camera
composition if work is done that affects camera
installation position (such as removing/installing
camera brackets, counterweights or replacing a
camera). Make sure camera images are displayed
properly via the inspection methods indicated in the
section "Checking Aerial Angle Camera Images" on
page 7-168. If any camera images are not displayed
properly, contact your authorized dealer.
