Select 'Initialize 1 Device' . A progress bar in the devices grid will indicate when the initialization process is
completed.
After initialization is complete, unplug the wGT3X-BT and replace the USB cap by turning clockwise with the
triangle tool. Be careful not to overtighten.
The device will begin collecting data when the selected start time elapses and will continue to collect data
until the stop time occurs (if selected), the battery is depleted, or the device is downloaded and reinitialized.
Note: If the start time elapses before the initialization process is complete, an error message will appear. Simply select
the 'Default' button in the Start Time section to reset the default start time and then select 'Initialize 1 Device' .
Note: Multiple devices can be initialized simultaneously using one or more ActiGraph approved charging hubs. In
this case, all devices will be programmed with the same initialization parameters and the Subject Info grid will
display serial numbers of all connected devices for assignment.
