With the control head face down, gently remove the PCB (13), along with the key-
pad (8) and lightspreader (7).
Do not disturb the positioning or height of the LEDs, as this is critical for reas-
sembly.
Carefully remove the LCD (6) and lens (12).
Lay the front panel (3) on a horizontal surface, with the light spreader (7) in place.
Remove the volume knob (1) and volume knob nut (5) to access the lightspreader
and keypad (8).
Before reassembly, the LCD and PCB edge connectors should be wiped with alco-
hol.
Take care to ensure the alcohol does not come in contact with the coating on the
light spreader, as this will dissolve on contact with alcohol.
