Control Cover Removal and Reinstallation

The cover panel is secured with two (2) captive coin-slotted screws. Coin-slot- ted screws allow a coin edge to be used as a screwdriver to remove the panel.

Multi-Position Mounting Feet

The mounting feet are designed to slide in both directions to clear installa- tion obstructions on the mounting surface.

WARNING! Before driving the mounting screws through any surface, be sure of what is behind that surface. Check for the gas tank, brake lines, and any vehi- cle wiring harness.

Vents (Side and Rear)

The cooling vents must be kept clear of obstructions once the amplifier is installed. Failure to do this could lead to premature thermal shutdown or ampli- fier failure.
