SERVICE NOTES
1) Remove the grille.
2) Access to the woofer is accomplished by gently prying the trim ring out of the counterbore, which is attached with a friction fit, using a small, flat-blade screw
2) Access to the woofer is accomplished by gently prying the trim ring out of the counterbore, which is attached with a friction fit, using a small, flat-blade screw
driver or similar tool. The four Phillips screws will then be visible.
3) Access to the HF/UHF sections and crossover network is accomplished by first extracting the upper four rubber grille retainers; this can be accomplished by
carefully pulling them out of their cavities with long-nosed pliers or a similar tool. Phillips screws will then be visible (power tools are not recommended here).
Remove the four screws, and then pull off the faceplate w/UHF driver attached to it.
