Replacing the chassis
Following the disassembly instructions, fully
disassemble the radio. Discard both the
chassis and main seal.
Inspect a new main seal to determine orienta-
tion and top/bottom surfaces. The tab is locat-
ed at the top of the radio. Note that the seal is
not flat. Ensure that the orientation is such
that the bends follow the groove on the new
chassis.
Locate the tab in the hole at the top of the
chassis groove. Place top corners. Smooth seal
into position across the top of the chassis.
Place the seal in the groove at the bottom of the
radio and locate the corners.
Starting at the corners and moving towards
the middle, work the seal into place along both
sides of the chassis. Be careful not to stretch the
seal.
Ensure that the seal is fully inserted in the
groove all the way around the chassis. Ensure
that it is not pinched when the radio is
reassembled.
