NOTE
Caution should be used while engaging the radio in the cassette the first few times until the cabling in the cassette mount assembly has had an opportunity to work into its permanent location. To insure proper first time engagement, the following procedure should be used:
Insert radio into cassette mount opening and slide in until you feel some spring resistance. Holding the handle, jiggle the radio a bit to give it a chance to find the connectors. Then engage the radio handle in the sheet metal hooks which protrude from the lower corners of the cassette mount casing. Rotate the handle upward to fully engage the radio. See Figure 30. DO NOT FORCE THE CONNECTOR ENGAGEMENT portion of the travel.
