6.0 SERVICING

6.1 Cabinet finish

To remove marks and scuffs use a soft brush. If necessary, a little warm water and detergent can be
used but under no circumstances use a solvent or abrasive cleaner. 

6.2 Driver removal

Lay the cabinet on its back. Remove the six hexagonal screws and set aside. Ease the driver from
the front of the cabinet taking care not to mark the front surface. Remove the driver, note the polarity
of the internal connections and disconnect the internal wiring. Take care not to damage the moving
parts of the LF driver. To refit the driver, connect the cables from the crossover to the LF terminals.
Fit the driver into the mounting hole, making sure that the internal connecting cables are not trapped
or able to touch the LF cone. Fasten the screws finger tight and then progressively tighten them
down with the appropriate Allen key.
Repeat the same procedure for the HF driver.

6.3 Crossover

The crossover is mounted on the rear of the terminal panel. To inspect it, remove the panel by
releasing the hexagonal screws. Take care to avoid undue stress on the cables and components.
To remove the crossover completely the cables must be disconnected from the drive unit. Please
proceed as above to remove the drive unit.
