AUDIO TEST PROCEDURES
Functional Tests
Equipment Required
Audio Signal Generator
Notes:
1. Begin the test with no power applied.
2. Confirm the Audio Signal Generator output is set to zero volts before connecting.
1. Twiddler Air Leak Test
1.1 Connect the audio signal generator to the mini jack AUX input on the back of SoundDock 10.
1.2 Set the signal generator output to:
A. Voltage = 0V
B. Frequency = 250Hz +/- 10%
1.3 Apply power to the SoundTouch 30 and select AUX. Set volume to 60% by using the volume control.
1.4 Set the Signal generator output to:
A. Input Voltage = 1.0Vrms +/- 10%
B. Frequency = 250Hz +/- 5Hz
1.5 Listen for air leaks around all the cabinet seams, joints, and wire harness throughholes.
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 distance less than 1ft (0.3M) from any exterior surface of the enclosure.
2. Woofer Air Leak Test
2.1 Set the signal generator output to:
A. Input Voltage = 0.570 Vrms +/- 10%
B. Frequency = 44Hz +/- 5Hz

FAIL if any air leaks can be heard at a distance less than 1ft (0.3M) from any exterior surface of the enclosure.
3. Left / Right Driver Test
3.1 Apply an input signal to the SoundTouch 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.
3.2 Reduce generator output to zero volts
3.3 Repeat step 3.1 for the right channel.
3.4 Reduce input signal to zero volts and reconnect the right channel.

AP COMMAND SET UP
TAP command set up
Equipment Required
Hardware
Computer w/serial port
RS232 to TTL converter
Lifestyle ETAP Cable, P/N 264565
Soundlink ETAP adapter P/N 347062-0005
Software
TeraTerm terminal emulator
(Download at sourceforge.jp/projects/ ttssh2/)
Notes: TAP commands can be sent to the SoundTouch 30 system by connecting a PC to the AUX IN connector. An ETAP cable, ETAP Cable adapter and RS232 to TTL Converter are required for this communication. Both ETAP cables are available from Bose (see part numbers above). The RS232 to TTL Converter is made by B+B electronics, model number 232LPTTL.
TAP commands are needed for the following
procedures:
A. WiFi Link Test
B. Serial Number Programing
C. Setting WiFi Country Code
1. Tera Term Terminal USB set up
Tera Term is a terminal emulator and can be downloaded at sourceforge.jp/projects/ ttssh2/. It is the interface used to send commands to the SoundTouch 30 product.
1.1 Connect the SoundTouch as shown in the diagram below.

2. Teraterm set up
2.1 Launch a Tera Term terminal window and select serial communicaton.
2.2 Select setup, then serial port to set the baud rate to 115,200 data to 8 bit, parity to none, stop to 1 bit and flow control to none.
2.3 Connect power to the SoundTouch 30. The product will boot, and the Tera Term window will display the boot information
WI-FI TEST PROCEDURE
1. Wi-Fi Functional Test Set Up
This test uses TAP commands to connect the product to a Wi-Fi network and stream audio from a Bose URL. The Bose SoundTouchTM application can be used in place of this test.
Note: Do not download the audio file from the test URL. Determine the security type for your router and select the appropriate TAP command for Connecting to a Wi-Fi Router. (WEP, WPA, or no security)
2. Connecting to a Wi-Fi Router
2.1 Enter the following TAP command for your router security type setting. Do not enter parentheses.
2.1.1 WEP Security Type airplay wep profile (SSID) (Password)
2.1.2 WPA Security Type airplay wpa profile (SSID) (tkip or aes)
(Password)
2.1.3 No Security
airplay Wi-Fi profile (SSID)
2.2 Wait for the Wi-Fi indicator on the product’s display to turn solid white. This may take up to a minute. If the indicator does not turn white, enter the TAP command again.
3. Testing the Wi-Fi Module.
3.1 Enter the following TAP commands. sys configuration DemoAudioURL worldwide.bose /downloads/assets/audio/take5.mp3 sys configuration DemoNetworkEnabled true demo enter
3.4 The song “Take 5” should play. Listen for clean undistorted audio.
3.5 Enter the following TAP command to exit the Wi-Fi test. demo exit
Note: A Tera-Term macro that includes these TAP commands is available for download on the product’s repair information page. Place the macro file in the same folder as your Tera-Term program. Open Tera-Term, select Control, Macro, wifi_test.ttl. Once the macro runs, follow the prompts.
4. Factory Reset.

HI-POT TEST
1. Hi-Pot Test
CAUTION - All units that are disassembled as part of a repair MUST be Hi-Pot tested before being returned to the customer. This test applies a high voltage to the AC line cord and measures the current leakage to the chassis and/or other metal parts on the outside of the unit to check for potential shock hazards.
If the unit fails Hi-Pot test, it must be rerturned to the technician for troubleshooting and repair of the problem, after which it must be Hi-Pot tested again to ensure that it now passes the test.
Hi-Pot Tester Settings:
Type of product: 120 VAC 2-wire Class II
Test Voltage: 1500 VAC
Trip Current Limits: 2mA min, 6mA max
Ramp: 1 sec
Dwell: 2 sec
Type of product: 220 VAC 2-wire Class II
Test Voltage: 2500 VAC
Trip Current Limits: 2mA min, 6mA max
Ramp: 1 sec
Dwell: 2 sec
2. Hi-Pot Test Procedure
2.1 Connect the positive side (hot) of the HiPot tester to both terminals of the AC mains input.
2.2 Connect the return of the Hi-Pot tester to all connections on the 3.5mm audio jack, ground shell on either USB connector and all points on the Ethernet connector.
2.3 Connect the continuity check terminal of the Hi-Pot tester to the shell of the USB. (all grounds are connected to the same point internal to the product, so only a single connection point is required). This test must be performed only after the system has been completely assembled.
Failure of this test indicates a faulty transformer, defective or incorrectly dressed primary wiring, improperly attached leads, surface contamination of either the power supply board or the I/O connector board, or incorrectly adjusted trip point on tester.
