Data Summary
A new feature being introduced with the wGT3X+ and wActiSleep+ is data summary. This feature
provides a wireless mean to rapidly tell information about the subject data. Daily and cumulative totals
are provided for counts, steps, and cut points. Additionally, a non-sedentary value is presented in order
to allow the researcher to rapidly gain insight into subject wear time/compliance.

Battery
All ActiGraph devices use a lithium ion rechargeable battery that has a maximum voltage of
approximately 4.20 volts. At 3.1 volts the devices enter a low voltage mode state (HALT mode).
approximately 4.20 volts. At 3.1 volts the devices enter a low voltage mode state (HALT mode).
In order to slow the aging of the Lithium Ion battery, it is recommended that devices be stored in a
partially charged state (40 – 60% battery capacity) in low ambient temperatures. Table 4 demonstrates
the impact of storage temperature and charge state on battery long term capacity.
