Modification Procedure

1. Remove radio.

2. Remove spring contact with harness and discard.

3. Exchange the radio chassis bottom cover for one equipped with a spade connector at its rear center, if not already so equipped (Figure 8).
4. Affix installation note label directly below existing label reading "2 X 20 Watt..." to top cover of radio chassis.

Note: Exchange radios manufactured after 10/86 already have the new cover and label. For these radios, disregard steps 2 and 3.
