I have a JVC kd-r210 cd receiver installed in a motrohome outdoor entertainment center that I need to replace a fuse, as it has no power. I need to get at the back of the unit to do this-replace the 15 A fuse. I have the control panel and trim plate removed. I need to remove the unit to get at the fuse but I do not have the handles--is the another way to do this. I am presently at a campground with this problem.
