System 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.
2. Confirm the Audio Signal Generator out-
put is set to zero volts before connecting.
1.1 Air Leak Test
1.1 Connect the audio signal generator to the
mini jack AUX input on the back of Sound-
Dock ® Portable.
1.2 Set the signal generator output to:
A. Voltage = 0V
B. Frequency = 80Hz +10%
1.3 Apply power to the SoundDock Portable,
the system will default to the AUX input if
there is nothing connected to the dock.
Press and hold the volume plus button for 15
seconds, this should set the system to max
volume.
1.4 Set the Signal generator output to:
A. Voltage = 100mV +10%
B. Frequency = 65Hz +10%
1.5 Listen for 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 of less than 1ft (0.3M) from any
exterior surface of the enclosure.
FAIL if any air leaks can be heard at a dis-
tance less than 1ft (0.3M) from any exterior
surface of the enclosure.

TEST PROCEDURES

2. Left Right Driver Test
3. Frequency Sweep Test
29
2.1 Apply the input signal to SoundDock
Portable left channel only. Set generator as in
step 1.3 and 1.4, except set the frequency to
800Hz and confirm that only the left driver
plays.
2.2 Reduce generator output to zero volts
2.3 Repeat step 2.1 for the right channel.
2.4 Reduce input signal to zero volts and
reconnect the right channel.
3.1 Set audio signal generator to:
A. Voltage = 100mV +10%
B. Sweep range = 40 HZ - 5KHz +10%
3.2 Execute the sweep for a minimum of five
seconds up and then down the range.
3.3 Listen for any extraneous noises such as
buzzes, rattles, ticks, and distortion.
PASS if no noise can be heard at a distance
of less than 1ft (0.3M).
FAIL if any noise can be heard at a distance
less than 1ft (0.3M).
3.4 Reduce the input signal to zero volts.
