5. Amplifier PCB Assy Removal
5.1 Remove the four Phillips-head screws
securing  the Amplifier  PCB Assy  to  the
speaker housing as shown in figure 6.0.
5.2 Using the heatsink fins and FF cable,
carefully  lift  the Amplifier  PCB Assy  away
from the speaker  housing.
5.3 Disconnect the IR Receiver PCB FF
cable and the Left & Right driver cables from
the Amplifier  PCB.
5.4 Amplifier PCB, see figure 6.1.
5.5 Position the left and right driver harness
as shown in figure 6.2. This will ensure that
you don’t confuse the phasing of the drivers
when reconnecting them to the PCB.

6. Infrared Receiver PCB Removal
6.1 Peel back the foam tape concealing the
IR Receiver PCB. See figure 7.0 for details
6.2 Remove the Phillips-head screw secur-
ing the PCB in place
6.3 Disconnect the four conductor FF cable
from the IR PCB.
Note: This cable provides signals to the
DSP IC via the Amplifier PCB.
7. Driver removal
7.1 Remove four phillips-head screws
securing the driver to the speaker housing.
See Figure 8.0.
7.2 Note the routing of the driver harness
before fully extracting the driver. See figure
8.0.
7.3 Ensure acoustic foam is positioned
behind the driver. See figure 8.3.

							242.2Reduce generator output to zero volts.
2.3Repeat step 2.1 for the Right channel.
2.4Reduce Input signal to zero volts and
reconnect SoundDock’s right channel.
3. Frequency Sweep Test
3.1Set audio signal generator to:
A. Voltage = 750mV 
+10%.
B. Sweep Range = 40HZ - 5KHz 
+10%.
3.2Execute the sweep for a minimum of five
seconds up and then down the range.
3.3Listen for any extraneous noises such as
buzzes, rattles, ticks, and distortion.
PASS if no noise can be
heard at a distance 
> 1ft 0.3M).
FAIL if any noise can be
heard at a distance of 
> 1ft (0.3M).
3.4Reduce the input signal to zero volts.
4. Button & Remote Control Test
4.1Set Audio Signal generator to:
A. Voltage = 100mV 
+10%.
B. Frequency = 100Hz
4.2Using the Volume Down button, momentarily
press & hold the Volume Down button.
Verify that the SoundDock responds to the
commands.
4.3Using the Volume Up button, momentarily
press & hold the Volume Up button.
Verify that the SoundDock responds to the
command.
4.4Using the Remote control, turn the
volume down. Verify that the SoundDock
responds to the command.
4.5Adjust the generator to zero volts and
disconnect it from the SoundDock.
TEST PROCEDURES
SoundDock Functional Tests
Equipment Required
Digital Multi-meter
Audio Signal Generator
iPod Eliminator PCB, P/N 287089
Notes:
1.Begin the test with no power applied to
the SoundDock.
2. Confirm the audio signal generator output
is set to zero volts before connecting it to
the SoundDock.
3. Remove the input signal before removing
power from the SoundDock.
1. Air Leak Test
1.1Install the iPod Eliminator board into
SoundDock’s docking cradle and connect
the audio signal generator to the eliminator
board via a 3.5mm minijack cable.
1.2Apply power to the SoundDock.
(Note: This will cause SoundDock to ramp
to a suitable volume level for the test.)
1.3Set the signal generator output to:
A. Voltage = 750mV 
+10%.
B. Frequency = 80Hz 
+10%
1.4Listen for potential air leaks around all
the cabinet seams, joints, and wire harness
through-holes.
PASS if no audible air leaks can be heard at a
distance
>1ft 0.3M) from any exterior surface of
the enclosure.
FAIL if any air leaks can be heard at a distance
>1ft (0.3M) from any exterior surface of the
enclosure.
1.5Reduce the input signal to zero volts.
2. Left Right Driver Test
2.1Apply the input signal to SoundDock’s left
channel only. Set Generator as in step
1.3, except set the frequency to 800Hz and
confirm that only the left driver plays.
