4. Operating Instructions
4.1 Setting Daily Alarms
The watch supports up to 15 discrete vibrating alarms per day. To set an alarm:
- Access the alarm setting mode (consult the watch's specific button sequence).
- Select an alarm slot (e.g., Alarm 1, Alarm 2).
- Set the desired time for the alarm (e.g., 8:00 AM, 9:35 AM).
- Confirm the setting. The watch will vibrate silently for 60 seconds at the set time.
4.2 Using the Timer Function
The timer function provides repetitive vibrations at set intervals. This is useful for regular reminders like hydration or focus tasks.
- Enter the timer setting mode.
- Choose your desired interval: 1 min, 5 min, 10 min, 15 min, 30 min, 45 min, 60 min, 90 min, 120 min, or 180 min.
- Activate the timer. The watch will vibrate at the selected interval throughout the day until deactivated.
4.3 Power-off Memory
The e-vibra GU15 watch is equipped with power-off memory. All your alarm and timer settings are saved automatically, so there is no need to reconfigure them if the watch powers off or runs out of battery.
5. Maintenance
5.1 Cleaning
To clean your watch, wipe it gently with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials, as these can damage the silicone strap and display.
5.2 Water Resistance
The e-vibra GU15 watch is water-resistant. This means it can withstand splashes, rain, and brief immersion in water, making it suitable for daily wear and activities like hand washing. It is not recommended for swimming, showering, or prolonged submersion.

5.3 Battery Care
To maximize battery life, avoid fully discharging the watch frequently. Charge it when the battery indicator is low. Store the watch in a cool, dry place when not in use for extended periods.
6. Troubleshooting
- Watch not vibrating: Ensure alarms or timers are correctly set and activated. Check the battery level and charge the watch if necessary.
- Watch not holding charge: Verify that the USB charging cable is securely connected to both the watch and the power source. Try a different USB port or adapter. If the issue persists, the battery may require service.
- Incorrect time display: Re-enter the time setting mode and adjust the time. Ensure the 12/24-hour format is set correctly for your preference.
- Buttons unresponsive: Ensure the watch is sufficiently charged. If the issue persists, try restarting the watch by allowing the battery to fully discharge and then recharging it.
