What’s in the Box
Getting Started
Setting up Your Watch
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
Letsfit 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 ID205L.
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.
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.

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.
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 bar on the screen and you can press
the function button to check the battery level.
Remove the watch from the power supply once fully charged.
● USB charger requirement: DC USB port (5V-500mA)
● Charging time: 2-3 hours

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.

All-day Wear and Exercise
Wearing Your Watch
- 4 -
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.
