5. Factory Default
It is important to reset the unit to its factory default
setting after testing since the unit stores the last
volume setting. Some tests required the volume to be
set at full (100). Because the last volume setting was
100, when first turned on by the customer, the unit
would be at full volume.
Note: Factory default volume is 30.
5.1 Use the remote to turn on the unit or issue TAP
command “remote 0”
5.2 Issue TAP command “fd”
5.3 Turn the unit off with the remote or TAP com-
mand “remote 0”
5.4 Remove power from the unit.
Note: To check the volume setting, turn the unit on
with the remote or by issuing TAP command “remote
0”. Issue the TAP command “VO” to view the volume
setting. Response = 0/30/100. The middle number is
the volume level the unit will turn onto.
6. Hi-Pot Test, Mandatory Test
Important note: If the unit has been disassembled,
a Hi-Pot test must be performed before returning the
unit to the customer to ensure there is no potential
for a shock hazard.
6.1 Test points are from the AC power input (both
line and neutral) to all connectors on the rear of the
product.
6.2 Hi-Pot tester settings for all voltage variants.
Type of product: 200-240 VAC 2-wire Class II
Test Voltage: 3000 VAC
Trip Current Limits: 1.5mA min, 2.16 mA max
Ramp: 1 sec
Dwell: 3 sec
6.3 Connect the AC line cord into the rear of the
Bose
®
Solo TV Sound System. Connect the
other end of the AC line cord to the Hi-Pot tester.
6.4 With the tester set to the above settings,
perform the test. Failure of this test indicates a faulty
transformer, incorrectly dressed primary wires, or
incorrectly adjusted trip point on tester. Repair any
fault found.
Performance Verification Procedures
4. Auto Select
This is only needed if the input test is performed with
all inputs connected. Otherwise, the unit’s auto
select circuit will select just the Optical input - the
highest performance signal. The auto selection
sequence is Optical, Coax, Analog.
4.1 Issue the TAP command “remote 0” to turn the
unit on, or press the remote ON button.
4.2 Issue the TAP command “VO 100” to set the
volume to maximum level.
4.3 Issue TAP command “audio auto, 0” to disable
auto input selection.
4.4 Apply a 70 Hz, 50 mVrms signal to the left and
right analog input.
4.5 Issue TAP command “audio input, 0” to select
the Analog input.
4.6 Apply a 70 Hz, 50 mVrms signal to the left and
right input of the A/D converter.
4.7 Connect the A/D converter Coax output to the
unit’s Coax input.
4.8 Issue TAP command “audio input, 1” to select
the Coax input.
4.9 Connect the A/D converter Optical output to the
unit’s Optical input.
4.10 Issue TAP command “audio input, 2” to select
the Optical input.
4.11 Issue TAP command “audio auto, 1” to enable
auto input selection before returning the unit to the
customer.
