Chase Street Pensacola, FL 32502 tel (850) 332-7900 fax (850) 332-7904 TAS14DOC07 User’s Manual Page 10 of 21 Introduction The ActiGraph Link activity monitors provide objective measurements of human activity and are used in many research and clinical applications. They include a microelectromechanical system (MEMS) based accelerometer, gyroscope, magnetometer, and a capacitive touch based wear sensor as data collection end points. No formal training is required to use the ActiGraph Link and patients may be the intended operator. This document will serve as the only necessary training guide needed to get full functionality from the device. Specifications and Functionality of the ActiGraph Link Data The Link includes two accelerometers, gyroscope, and magnetometer sensors. Data will not be negatively affected by lint, dust, or direct sunlight. Acceleration Acceleration is measured by two accelerometers; a primary that is utilized for all historical and standard data collection efforts and a secondary which is used in very specific use cases where a higher dynamic range is necessary. Parameter Primary Secondary Units Axis 3 3 Sensitivity 0.5 4 mg/LSB Dynamic Range +/-16 +/- 8 g Table 1 – Accelerometer Key Specifications Acceleration data from the primary sensor is sampled at rates ranging from 30 Hz to 100 Hz (user selectable) and the secondary accelerometer data is sampled at a fixed 100 Hz. Output from both devices are stored in a raw, non-filtered/accumulated format in the units of gravity (g’s). This data is stored directly into a non-volatile flash memory. The accelerometer is very sensitive and is accurate within +/- 0.5% of the data collected. Gyroscope A three axis gyroscope collects angular velocity in units of degrees/sec. Data is sampled at 100 Hz. Parameter Value Units Axis 3 Sensitivity 0.06 Deg/LSB

Data is sampled at 100 Hz. Parameter Value Units Axis 3 Sensitivity 0.6 µT/LSB Dynamic Range +/- 4800 υT/LSB Table 3 – Magnetometer Key Specifications Steps Step counts are accumulated on a per-epoch basis and are based on accelerometer data collected on the vertical axis. An algorithm present in the device firmware filters out the accelerometer’s baseline noise level to help accurately accumulate the steps-per-epoch. Inclinometer The inclinometer feature can help users identify the orientation of the device and, more importantly, when the device itself was taken off. Each epoch is flagged with a number (1 through 4) to indicate the orientation of the device during that epoch. For ActiGraph Link devices, this is done within the ActiLife software when converting the *.gt3x file to *.agd format. As noted, the inclinometer feature is only valid when the device is worn vertically on the point of the hip. More details are available in the Inclinometer Whitepaper. Important The inclinometer feature is only valid if the device is worn on the hip with Axis 1 upward facing. Inclinometer Code (Stored with each Epoch) Interpretation 0 Device Off (Not Being Worn) 1 Subject Standing 2 Subject Lying Horizontal 3 Subject Sitting Table 4 - Inclinometer Definitions

Chase Street Pensacola, FL 32502 tel (850) 332-7900 fax (850) 332-7904 TAS14DOC07 User’s Manual Page 12 of 21 Off Indication on ActiGraph Link versus other devices The Inclinometer feature offers researchers the ability to detect periods of time during which the device was not worn. For devices other than the wGT3X+, wActiSleep+, GT3X+, and ActiSleep+, the inclinometer algorithm makes this prediction by examining the angle at which the device is placed. In the wGT3X+, wActiSleep+, GT3X+, and ActiSleep+ devices, off detection is performed by analyzing both the angle at which the unit is placed as well as the length of time the device remains still. Absolute stillness for three (3) minutes indicates that the unit is likely in an “off” condition regardless of orientation. As such, epochs that follow three motionless minutes of activity are flagged as “off,” i.e., the inclinometer code is equal to zero. These values are not retroactive. That is, the first three minutes of zero activity are not flagged as “off.” In addition, 30 minutes in the “off” orientation will cause the inclinometer value to indicate off after that time period has elapsed regardless of motion. At this time, the inclinometer feature is being validated by the research community. Low Frequency Extension The Low Frequency Extension (LFE) option, though not a mode or channel, is another data collection option during post-processing for the ActiGraph Link. The Normal proprietary filter algorithm used in ActiGraph products is used to eliminate any acceleration noise outside of the normal human activity frequency bandwidth. This filter is customized to work with ActiGraph’s Energy Expenditure Algorithms. The LFE option, when enabled, extends the lower end (baseband) of the filter cutoff, effectively expanding the bandwidth of the accumulated data. This option is useful when measuring actigraphy data for subjects who move slowly or take very light steps (for example, the elderly). For more details, contact ActiGraph at support@theactigraph.com. Data Collection During initialization, the user chooses the raw data sample frequency (30Hz up to 100Hz in 10Hz increments). The ActiGraph Link collects data from all on-board sensors in raw data format. Data recorded includes: • Vertical Axis Activity Acceleration Data (Axis 1) • Horizontal Axis Activity Acceleration Data (Axis 2) • Perpendicular Axis Activity Acceleration Data (Axis 3) • Ambient Light (Lux) Although Steps and Inclinometer are not directly measured during data collection, these values can be derived from the 3-axis data during *.gt3x file decompression. Unlike previous ActiGraph products, the ActiGraph Link does not filter or accumulate data into epochs. Raw data is collected at the selected sample rate and is post-processed in the ActiLife. Because these devices collect data from all sensors at all times, users can generate native ActiLife *.agd files containing any desired combination of parametric data at a later time. This helps facilitate backward compatibility

Figure 1 – Raw Data Collection and Processing Water Resistance ActiGraph Link devices are water resistant in accordance with IEC 60529 IP27, or immersion in one (1) meter of water for up to 30 minutes Wireless In addition to the standard features and functionality of their predecessor devices (wGT3X+ and wActiSleep+), ActiGraph Link provides a wireless interface by way of Bluetooth 4.0TM wireless communication protocol. This 2.4 GHz based interface allows for interoperability with millions of already fielded nodes as well as provides a means of rapidly gathering device and/or subject information. The wireless functionality can be disabled when not needed in order to increase battery life. Heart Rate By way of Blue Tooth Smart chest straps, the ActiGraph Link is capable of measuring and storing both standard heart rate in Beats Per Minute (BPM) format as well as providing R-to-R measurements thus enabling the researcher to better understand heart the subject’s activity profile. Wireless Reporting and Control In addition to enhancing and increasing the sources for data collection, the wireless functionality of the ActiGraph Link enables the user to perform many functions that previously required USB connection or weren’t possible before. Many functions can now be performed in the field rather than requiring the researcher to be tethered to a computer in the lab. Initialization The ActiGraph Link can be fully initialized wirelessly. This can be performed with ActiGraph’s new ActiLife Mobile available on the iPhone and Android platforms. Device Status Device specific status information can be obtained. Some of the items retrieved include; firmware version, battery voltage, current mode, subject name, and device serial number.

Chase Street Pensacola, FL 32502 tel (850) 332-7900 fax (850) 332-7904 TAS14DOC07 User’s Manual Page 14 of 21 Stopping the device In order to stop the device from collecting data, the device needs to be plugged into a computer with the ActiLife Software running. One easy way to stop the device from collecting data is to set a stop time during initialization. Once a device is told to stop, it will go into HALT mode and go into a low power stopped state. Another way to get a device to stop collecting data is to plug it into a computer with the ActiLife Software running and update the firmware on the device. This also will put it into HALT mode and have the device go into a lower power stopped state. Unexpected operations and events If a device performs in an unexpected manner and does not collect data, does not perform 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 (877) 497-6996 and is available every week, Monday through Friday, 8A.M. to 5P.M Central Standard Time. Customer Service may also be contacted through email at support@theactigraph.com. 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 and 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 possibly completely 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 and described by ActiGraph. Battery All ActiGraph devices use a lithium polymer rechargeable battery that has a maximum voltage of approximately 4.20 volts and have a total life expectancy of five (5) years. Even though these batteries are replaceable, only ActiGraph personnel are to replace the batteries. At 3.1 volts the devices enter a low voltage mode state (HALT mode). 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. Every three (3) months plug the devices in to monitor their voltages and to extend the life expectancy of the battery. Table 5 demonstrates the impact of storage temperature and charge state on battery long term capacity.

ActiGraph Link Sample Rate (Hz) Battery Life (Days) Memory Limit (Days) 30 10 120 Table 7 – Battery life based on no sleep (24 hrs active). Low Voltage Mode (HALT) ActiGraph devices enter a “Low Voltage Mode” (or HALT) state when the battery discharges beyond a point of being able to power the device. In this mode, all important variables and data are stored in flash memory to secure the device download. Because the device’s internal clock stops in HALT mode, the device cannot be recharged and redeployed; the device must be downloaded and reinitialized to continue use. Recharging Recharging is automatic and is accomplished by connecting the device to ActiGraph’s charging station. Charging time will depend on the battery life, but typically will not exceed three hours for a fully depleted battery to become fully charged. If the battery voltage drops below 3.1 volts while in use, the device will not have sufficient power to collect data and will display a warning to the user. The battery level, reported in volts, can be viewed at any time by starting the ActiLife software and plugging in the device. Important: ActiLife will not allow initialization if the voltage is below 3.85 volts.

Chase Street Pensacola, FL 32502 tel (850) 332-7900 fax (850) 332-7904 TAS14DOC07 User’s Manual Page 17 of 21 Wearing the Device All ActiGraph activity monitors are designed to monitor activity and record energy expenditure (calories spent during normal activity, METs, everyday activity, and exercise). Additionally, these devices can also function as a very accurate sleep assessment tool2. While collecting day-to-day energy expenditure data, the device should be affixed securely to the body’s center-of-mass to ensure the most accurate caloric measurements. Wrist worn (non-validated) EE for kids is now available for 3-axis ActiGraph devices. When being used for sleep assessment, ActiGraph devices may be worn anywhere on the body: wrist, waist (hip), arm, or ankle. It is recommended that children under 12 years of age wear ActiGraph devices on the elastic belt (versus the adhesive belt clip) as it is the most secure way to wear the device. Belt loop pouches, wrist and ankle straps are also available. If irritation of the skin occurs due to wearing the device, discontinue wearing the device and consult a doctor for treatment. Although the Polycarbonate and Polyvinyl Chloride 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. Also, notify the individual that issued the device to you that you have taken the device off since data collection will be effected. Miscellaneous Device Information Degradable Components ActiGraph’s devices are made with high quality components that are not subject to deterioration over time. The battery within each device is the only component that has a determined life expectancy (5 years). If a device seems to be under-performing, call ActiGraph’s Customer Service department immediately so the problem may be resolved. Batteries are only to be changed by ActiGraph trained personnel. Other Possible Negative Effects Pets have the potential to destroy a device. Keep devices away from pets and other animals that may chew on, bite, urinate on, swallow, and destroy a device in any other method imaginable. Wear Locations ActiGraph’s devices can be worn in 6 different locations; the ankle, thigh, in a pants pocket, on the waist, wrist, or on a lanyard around the neck. When initializing the ActiGraph Link within ActiLife, choose the appropriate wear location to ensure accurate data collection. 2 Sleep analysis can also be performed by purchasing ActiGraph’s ActiSleep analysis program, which is part of the Virtual Trainer, web-based, analysis software. Formulas for this tool were developed by Dr. Avi Sadeh. Department of Psychology, Tel Aviv University.

For example the serial number MRA3A29120016 means: • MRA3 = device model • A = device model version • 29 = week of the year it was manufactured (29th week) • 12 = year it was manufactured (2012) • 0016 = number of device manufactured that week Cleaning the Device ActiGraph devices are approved to be cleaned with a non-abrasive cloth and isopropyl alcohol. For optimal results, apply isopropyl alcohol to the cloth, clean the device for 15-20 seconds, and let air dry. ActiGraph devices are not to be sterilized because damage may occur. Though ActiGraph 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. Device Storage and Life Expectancy There is no specific requirement for storing ActiGraph devices but a dry location with temperature limitations between 0°C and 50°C is suggested. For optimal battery life expectancy, routinely charge the device according to Table 5. 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 performance of the components inside the device does not degrade over time so the life expectancy of a device is immeasurable. Device Maintenance ActiGraph’s 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, will be made available to the trained ActiGraph service technicians.
