SAFETY INFORMATION
1. Parts that have special safety characteristics are identified by the symbol on schematics
or by special notes on the parts list. Use only replacement parts that have critical characteristics
recommended by the manufacturer.
2. Make leakage current or resistance measurements to determine that exposed parts are
acceptably insulated from the supply circuit before returning the unit to the customer.
Use the following checks to perform these measurements:
A. Leakage Current Hot Check-With the unit completely reassembled, plug the AC line cord
directly into a 120V AC outlet. (Do not use an isolation transformer during this test.) Use a
leakage current tester or a metering system that complies with American National Standards
Institute (ANSI) C101.1 "Leakage Current for Appliances" and Underwriters Laboratories (UL)
UL6500 / UL60065 / IEC 60065 paragraph 9.1.1. With the unit AC switch first in the ON position
and then in OFF position, measure from a known earth ground (metal waterpipe, conduit, etc.)
to all exposed metal parts of the unit (antennas, handle bracket, metal cabinet, screwheads,
metallic overlays, control shafts, etc.), especially any exposed metal parts that offer an electrical
return path to the chassis. Any current measured must not exceed 0.5 milliamp. Reverse the
unit power cord plug in the outlet and repeat test. ANY MEASUREMENTS NOT WITHIN THE
LIMITS SPECIFIED HEREIN INDICATE A POTENTIAL SHOCK HAZARD THAT MUST BE
ELIMINATED BEFORE RETURNING THE UNIT TO THE CUSTOMER.
B. Insulation Resistance Test Cold Check-(1) Unplug the power supply and connect a jumper
wire between the two prongs of the plug. (2) Turn on the power switch of the unit. (3) Measure
the resistance with an ohmmeter between the jumpered AC plug and each exposed metallic
cabinet part on the unit. When testing 3 wire products, the resistance measured to the product
enclosure should be between 2 and infinite MOhms. Also, the resistance measured to exposed
input/output connectors should be between 4 and infinite MOhms. When testing 2 wire products, the resistance measured to exposed input/output connectors should be between 4 and
infinite MOhms. If it is not within the limits specified, there is the possibility of a shock hazard,
and the unit must be repaired and rechecked before it is returned to the customer.
CAUTION: The Bose® ControlSpace® ESP-88 System, CC-16 and CC-64 Controllers
contains no user-serviceable parts. To prevent warranty infractions, refer servicing

ControlSpace® CC-16 zone controller is an elegant wall-
CC-64 Control Center
The Bose ControlSpace CC-64 control center is an
elegant, programmable, networked controller that
provides users with a simple and logical interface to
their ControlSpace system. Because the controller is
completely programmable, you can customize the
ControlSpace system, making only certain controls
available, and simplifying user interaction with the
system.
The CC-64 provides four rotary encoders with
circular LED arrays for a userfriendly method of
managing gain settings or scene selections. A fifth encoder provides control over programmed
“scenes” or presets. Four bank switch buttons redefine the four Gain/Selector control knobs,
providing quick access for up to 16 system gain controls or selectors. A large, 2-line by 40character backlit LCD provides the user with the names of the system elements they are controlling (gains, presets, etc.).
Using custom programming, the CC-64 can manage a variety of system elements, including
audio sources, scene selection settings, and specific system configurations. Each gain control
can be ganged so that a single control can be mapped to as many as sixteen system gains. The
CC-64 also supports a “custom mode” – intended for installers, not end users – in which any
parameter in the system can be viewed and changed using the LCD display and control knobs.

Test Setup Procedures
1. Ensure that the PC has valid IP address
[192.168.0.1 – 192.168.0.99]. To set your IP
address, click on START go to the CONTROL PANEL and click on NETWORK &
DIAL UP CONNECTIONS. Click on MAKE
NEW CONNECTION. Make a LAN connection. Click on PROPERTIES, then click on
INTERNET PROTOCOL TCP/IP. Set the IP
address to be between 192.168.0.1 and
192.168.0.99. The subnet mask will remain
255.255.255.0 and leave DNS settings
window blank. Click OK.
Once you open the ControlSpace software,
you should see a blank project window like
the one shown below.
d. Click on “Scan”.
2. Connect the ESP-88 chassis under test to
the AuBit switcher and the ATS-2 test station
as shown in Figure 7.
3. If not installed on the PC, install the Bose
ControlSpace Designer software. Once the
software is installed, click on the icon to start
the program.
4. Once the software opens, load the ESP88
TEST connection.csp file. This is a test file
that is has the ESP-88 chassis pre-configured as a straight pass-through to allow test.
If you don’t have this file, perform the following steps to set up the software and hardware for test.
e.The connected ESP will appear on
“Project view”. This case has no Technic.

TEST PROCEDURES
If there is no CC-16 or CC64 controller
connected, connect it now. You will also
need the power supply for the controller.
Click on the Properties view
.
This setup is a straight-through connection
for this test. Click the connect icon.
When the connection is completed, the
background color will change.
Check Firmware Version on properties
dialog box. Select ESP 1 view.
Click the connect icon again. At this point
the ESP is settled to the proper configuration
for this test.
After disconnect, the ESP-88 chassis must
be powered off and powered on again.
This power off sequence is needed by the
time test. It is recommended to use same
PC that set this configuration and to run the
ATS2 macro that will be described later.
This will avoid the time difference between
the two PC’s.
