Quick start guide
What’s in this Document
This manual gets you started quickly with setting up your watch. Setup ensures that your
watch can synchronize its data with the Fitdock app, where you can get detailed
information on your stats, view historical trends, log sleep, and more. As soon as setup is
complete, you’re ready to start moving. The remainder of the manual walks you through
every function on your IW1 Lite.
Setting up Your Watch
Charging Your Watch
Please fully charge your watch before initial use.
1. Insert the USB plug of the charging cable into the USB port on your computer or a
UL-certified USB wall charger.
2. Hold the other end of the charging cable near the port on the back of the watch until
it attaches magnetically.
2
3. Make sure the pins on the charging cable lock securely with the port. The connection
is secure when the watch vibrates and the battery icon with percent charged appears
on the screen.
When the watch shows that the battery is low,
connect the watch to a USB port with 5V-
500mA.
While the watch charges, there is a battery
progress circle on the screen and you can
check the battery level at any time.
4. Remove the watch from the power supply once fully charged.
USB charger requirement: DC USB port (5V-500mA)
Charging time: Approximately 2 hours
Disassembling / Assembling Your Watch
Disassembly
1. To remove the wristbands, turn over the watch and find the quick-release lever.
2. While pressing the quick-release lever inward, gently pull the wristband away from
the watch to release it.
3
3. Repeat on the other side.
Assembly
1. To reattach the wristbands, slide the pin (the side opposite the quick-release lever)
into the notch on the watch. Attach the wristband with the clasp to the top of the
watch.
2. While pressing the quick-release lever inward, slide the other end of the wristband
into place.
3. When both ends of the pin are inserted, release the quick-release lever.

Wearing Your Watch
All-day Wear and Exercise
For all-day wear when you’re not exercising, wear the device on your wrist horizontally, a
finger’s width below your wrist bone and lying flat, the same way you would put on a
watch.
For optimized heart rate tracking, keep these tips in mind:
1. Experiment with wearing the watch higher on your wrist during exercise. Because
the blood flow in your arm increases the farther up you go, moving the watch up a
couple of inches can improve the heart rate signal. Also, many exercises such as
bike riding or weight lifting require you to bend your wrist frequently, which is more
likely to interfere with the heart rate signal if the watch is lower on your wrist.
2. Do not wear your watch too tight. A tight band restricts blood flow, potentially
affecting the heart rate signal. This being said, the watch should also be slightly
tighter (snug but not constricting) during exercise than during all-day wear.

Pairing the Watch with Your Phone
Please pair the watch with your phone in the Fitdock app, NOT in the Bluetooth
settings of your phone.
1. Enable the Bluetooth of your smartphone.
2. Open the Fitdock app on your smartphone and go to the "Device" page, tap "Pair

Notes:
You can also search this device in the app to pair (Go to the "Device" page → "Pair
device" → "IW1 Lite").
Once the watch is connected to your app, the watch will automatically search and
reconnect itself if the connection is lost or when Bluetooth is restarted after manual
disconnection.
If the watch is unbound from the app, the information on the watch will be reset and
the watch will be restarted. Please do not unbind the connection unless there is an
issue that will require a reset.
The watch can only pair with one smartphone at a time. When pairing, please ensure
the watch and your smartphone is within 0.5 meters distance.
