DISASSEMBLY INSTRUCTIONS
1. Push to center of grille assembly to remove.
SERVICE ADVISORY
Do not power on or test amplifier section without
a load connected. For example, one should check
all speakers and speaker connections for open
conditions before applying power.
Note the orientation of the grille when installing.
2. Remove the 4 pcs screws at the back of aluminium ring.

5. Remove the 2 pcs screws at the back of the ring.
6. Split the ring apart allowing space to form between the ring and cabinet.
Push the ring toward the baffle and place two pieces of lint free cloth between
the ring and cabinet. Carefully remove the ring from the cabinet without
scratching the cabinet.
