Charge
Gently separate the strap from the module and plug the USB end into a standard charger or computer port.
Quick start
Charge the module before first use. Remove it from the strap, insert its built-in USB plug into a standard 5 V USB port, then reinstall it after charging. The band works without pairing it to a phone app.
Set the time
Show the clock with one press of the lower button, then hold the upper button for three seconds.
Explore
Press the lower button to cycle through steps, calories, distance and your three alarm screens.
Operation video
Watch the original C3Plus demonstration for a visual walkthrough. This video is hosted by YouTube and plays in an embedded player; YouTube may process viewing data under its own terms.
If the player is unavailable, open the tutorial on YouTube. The written instructions below work without the video.
Know the controls
A short press means press and release immediately. A long press means hold for about three seconds. The lower button changes the displayed function and confirms certain actions; the upper button opens settings and advances between fields.
| Presses | What appears |
|---|---|
| 1 | Current time; date appears shortly afterward |
| 2 | Step count |
| 3 | Estimated calories burned |
| 4 | Estimated distance in kilometers |
| 5–7 | Alarm A1, A2, then A3 |
| 8 | Sleep tracking status |
Button counts are based on the display being off. If you lose your place, let the screen turn off and begin again.
Time, date & 12/24-hour format
- Press the lower button once so the time is visible.
- Hold the upper button for about three seconds until the hour flashes.
- Short-press the lower button to change the flashing value.
- Hold the upper button to move through hour, minute, month, day, year and 12/24-hour format.
- When finished, stop pressing buttons. The band exits setting mode automatically.
Because this model does not sync to an app, you set its clock directly on the band.
Steps, timer & sleep setting
Reset your steps
Open the step-count screen with two lower-button presses, then hold the lower button for three seconds. The daily count also resets automatically at midnight. The maximum displayed count is 99,999.
Use the timer
On the clock screen, hold the lower button to enter timer mode. Short-press to start or pause; hold again to leave timer mode.
Check the sleep setting, if present
The supplied instructions describe an “S OF / S ON” screen after eight lower-button presses from the resting screen. If your band shows it, hold the lower button to change the displayed setting.
The factory's C3Plus product listing does not promise sleep analysis. The presence of this setting does not establish that your batch records or reports sleep data. Steps and calorie figures are general wellness estimates, not medical measurements.
Set one of three silent alarms
From the resting screen, press the lower button five times for A1, six for A2 or seven for A3. Hold the lower button to enable the selected alarm. An alarm must be enabled before its time can be changed.
- While the enabled alarm is displayed, hold the upper button until the hour flashes.
- Short-press the lower button to change the hour.
- Hold the upper button to select minutes, then short-press the lower button to adjust.
- Leave the buttons untouched to save and exit. Hold the lower button on an enabled alarm screen to switch that alarm off.
Charge without damaging the connector
Pull the strap away from the module carefully to expose the built-in USB connector. Insert the connector in the correct orientation into a standard 5 V USB port. A flashing red light indicates charging; a steady green light indicates a full charge.
Do not force the plug or leave the band charging long after the green light appears. Wipe moisture from the module after washing your hands or exercising. Use a normal USB power source rather than a fast-charge-only interface.

Common questions
Does the C3Plus need an app?
No. Time, alarms and activity screens are controlled with the wristband's two buttons.
Why does the time need to be set manually?
This model does not rely on phone pairing, so set the clock directly on the band after first use or if it loses time.
Why are my steps back to zero?
The daily count resets automatically at midnight. Holding the lower button on the steps screen also resets it manually.
Where can I get help if the band will not charge?
Check connector orientation and try another standard USB port. See the troubleshooting guide for a fuller checklist.
Find the right next step
If a control does not behave as expected, begin from the screen-off state and repeat the relevant button sequence above. For charging, display, time, steps, alarms and sleep problems, use the symptom-by-symptom troubleshooting guide; it separates checks you can do safely from issues that need seller support.
