A) The diagram below should be used as a guide for cutting and drilling the mounting and buttonholes in the
instrument panel. The dimensions shown are for the final cutouts. Allow extra clearance for any panel finish such as
powder coat. The plastic button caps are removable by grasping and pulling each off. The EDM-930 mounts in a
6x4.5 cutout. Mount the indicator using the figure below as a guide. If the panel has too many holes for a clean
installation, it is recommended that an .10” aluminum overlay panel be constructed and installed over the original
instrument panel and the EDM be installed into this overlay panel.
B) The Remote Alarm Display PN-790749 mounts in a 5/8 inch hole in the panel immediately above the Attitude
Gyro / D.G. / HSI +/- 0.5 inches from their centerline directly in front of the pilot.
