The appropriate wear location is dependent on specific research objectives and will be outlined in the study protocol.

Waist worn devices
Remove the clip at one end of the elastic waist belt.
1
Thread the belt through the wings on each side of the wGT3X-BT so the belt
2
lies flat against the back side of the device.
Replace the clip and adjust the length as needed.

The subject should be instructed to fasten the belt snugly around the waist
4
and position the wGT3X-BT in line with the armpit and knee with the USB
port cover facing up.
Wrist worn devices
From above the device, insert the thin end of the wear time wrist strap into
1
one of wGT3X-BT wings with the velcro side facing out. Pull until the thick end
of the wrist strap catches in the wing.
Insert the thin end into the opposite wing to create a loop. The strap should
2
not cover the back of the device.
Secure and adjust the wrist strap by folding the excess length outward and
3
fastening to the velcro.
The subject should be instructed to wear the device strapped securely to the
4
non-dominant wrist with the ActiGraph logo facing up when viewed like a
wrist watch.
Note: The wGT3X-BT can also be worn at the ankle, thigh, chest or other location for
specialized research applications. However ActiGraph does not offer specific wear
accessories for these locations at this time.
