CentrePoint Insight Watch Technical Manual
1.0 Introduction
The ActiGraph CentrePoint Insight Watch (CPW01) activity monitor provides objective measurement of
human activity and is used in many research and clinical applications. ActiGraph understands that
patients may be the intended operators of the ActiGraph CPW01 which is why it was designed to be
easy to use with no formal training required for use. This Technical Manual will describe all the
regulatory symbols, technical specifications, unique functionality, and safety statements are required for
regulatory purposes.
2.0 Specifications and Functionality of the CentrePoint Insight Watch
(CPW01)
2.1 Sensors
The CentrePoint Insight Watch includes one primary 3 axis accelerometer. It should be noted that data
will not be negatively affected by lint, dust, or direct sunlight.
2.1.1 Acceleration
Acceleration is measured using a digital MEMs accelerometer that is utilized for all historical and
standard data collection efforts.
Acceleration data from the primary sensor is sampled at 32 Hz, 64 Hz, 128 Hz, or 256 Hz (user
selectable). Outputs are stored in a raw, non-filtered format in the units of LSB’s. This data is stored
directly into a non-volatile flash memory. Table 1 lists some key specifications for the accelerometers
utilized in the CPW01 device.

2.1.1.2 Axis orientations
2.1.2 Operating the device
ActiGraph supplies a companion software application, CentrePoint Software, to communicate with the
device for the purposes of initiating data collection, sending configuration instructions, and downloading
the collecting data.
2.1.2.1 Starting and Stopping the Device
Initiation and stopping of data collection will be handled through CentrePoint Software. Users will be
trained on the CentrePoint Software to be able to use the CPW01 device.
2.2 Battery
The ActiGraph CPW01 device uses a lithium polymer rechargeable battery that has a maximum voltage
of approximately 4.20 volts and a total life expectancy of two to five (2-5) years. Batteries are to be
serviced by ActiGraph authorized personnel only. In order to slow the aging of the lithium polymer
battery, it is recommended that devices be stored in a partially charged state (40 – 60% battery capacity)

in low ambient temperatures. Also, every three (3) months devices need to be plugged in to monitor
their voltages and charged in order to extend the life expectancy of the battery. Using the backlight on
the device screen will impact the battery capacity.
Table 2 demonstrates the impact the storage has on the long term capacity of the battery.

IMPORTANT: ActiGraph’s devices do not come fully charged from the manufacturer and are
recommended to be charged fully before their initial use. If the battery performance is not performing
as expected, call ActiGraph’s Customer Service immediately.
2.3 Device Storage and Life Expectancy
The CPW01 is recommended to be stored at 20°C to achieve the maximum life expectancy and battery
life performance. The minimum/maximum storage temperature range is between -20℃ and 55℃. For
optimal battery life performance, routinely charge the device as described above.
The only limiting factor of an ActiGraph device when calculating life expectancy is the battery. The
battery has a life expectancy of five (5) years but can be replaced by ActiGraph personnel thus extending
the life of the device. The performances of the components inside the device do not degrade over time
so the life expectancy of a device is immeasurable.
2.3.1 Low Voltage Mode (HALT)
CPW01 will enter a “Low Voltage Mode” (or HALT) state when the battery discharges beyond 3.1 volts.
In this mode, all important variables and data are stored in flash memory to secure the device
download. The device can be downloaded via the CentrePoint system. Once the device’s battery has
been charged to an acceptable level the CentrePoint system can restart/resume the devices data
collection.

3. Miscellaneous Device Information
3.1 Device Irritation
If irritation of the skin occurs due to wearing the device, discontinue wearing the device and consult a
doctor for treatment. Although the copolymer materials are not known to be irritating to the skin, some
irritation to individuals with sensitive skin may occur. If this happens, consult your doctor for treatment
and stop wearing the device.
3.2 Degradable Components
ActiGraph’s devices are made with high quality components that are not subject to deterioration over
time. However, if a device seems to be underperforming, call ActiGraph’s Customer Service immediately
at [phone] so they problem may be resolved.
3.3 Other Possible Negative Effects
Pets have the potential to destroy a device. Keep devices away from pets and other animals that may
chew, bite, urinate on, swallow, and/or destroy a device in any other method imaginable.
3.3.1 Household Interference
Within a household environment many different factors can negatively affect the device. Putting a
device close to hot sources such as a fireplace or baseboard heater will melt the housing of a device and
destroy it. Putting a device in the freezer for extended periods of time will reduce the capacity of the
battery’s lifespan and negatively affect its performance. Putting a device in a microwave will destroy
various parts of the device and potentially destroy it. Wireless internet connections, wireless television
service, and other wireless services will not negatively affect the performance of the device. As a rule of
thumb, do not put the device in extreme cold or hot temperatures and do not apply any electrical
sources to the device unless explicitly approved by ActiGraph.
3.4 Wear Locations
The ActiGraph CPW01 is designed to be worn on the wrist. Other wear locations would have to be
selected in the CentrePoint system and ActiGraph should be contacted if other wear locations are
desired.
3.5 Button Operation
The button can be used to enable a backlight on the display for viewing in low light areas. Simply press
the button to activate the light.
3.6 Device Serial Number Label
Each device is equipped with a label stuck to it with pertinent device information inside the serial
number. For example the serial number (01)00853048008039 (21)CPW1E24180001 means:
●(01) = GS1 Application Identifier for GTIN

solution. For optimal results, apply isopropyl alcohol to the cloth, clean the device for 15-20 seconds,
and let air dry. The ActiGraph CPW01 devices are not to be sterilized because damage may occur.
Although the ActiGraph CPW01 devices are not required to be cleaned on any predetermined schedule,
it is advised that the devices be cleaned after each use by a user.
3.8 Device Maintenance
The ActiGraph CPW01 devices do not require routine maintenance or calibration. Calibration is
performed during manufacturing of the device and will last for the life of the device. If maintenance is
required on a device, or a piece of a device has gone missing, call ActiGraph Customer Support or visit
the support section on the ActiGraph website www.actigraphcorp.com and initiate an RMA for your
device.
Any critical components that require maintenance are to be performed by trained ActiGraph personnel
only. All necessary training manuals, schematics, parts listings, and other necessary documentation, are
only made available to trained ActiGraph service technicians.
3.9 Unexpected operations and events
If a device performs in an unexpected manner and does not collect data, or it is not performing as long
as expected, will not download data, or acts in any other manner that is unexpected, notify ActiGraph
immediately. ActiGraph’s Customer Service can be contacted at the phone number [phone] and
is available every week, Monday through Friday, 8 A.M. to 5 P.M. Central Standard Time. Customer
Service may also be contacted through email at [email protected].
