2. Setting Time and Date
Refer to the watch's on-screen interface for specific button presses to enter time setting mode. Typically, this involves pressing and holding a specific button (often labeled 'M' or 'Set') until the time display flashes. Use the adjustment buttons to set hours, minutes, and date, then confirm each setting.
Operating Instructions
1. Setting Alarms
The e-vibra RL16 supports up to 15 individual vibrating alarms. To set an alarm:
- Enter alarm setting mode (consult the watch's interface or quick start guide for button sequence).
- Select an alarm slot (e.g., AL1, AL2).
- Set the desired hour and minute for the alarm.
- Enable or disable the alarm.
- Repeat for additional alarms as needed.
Tip: For wake-up alarms, consider setting multiple alarms a few minutes apart for increased effectiveness.
2. Timer Function (Interval Reminders)
The watch also features a fixed interval timer for repeating reminders:
- Access the timer setting mode.
- Choose from preset intervals: 1min, 5min, 10min, 15min, 20min, 30min, 45min, 60min, 90min, 120min, or 180min (3 hours).
- Activate the timer. The watch will vibrate at the selected interval until manually stopped.
This feature is useful for regular reminders such as potty training or hydration.
3. Lock Function
To prevent accidental changes to time and alarm settings, the watch includes a lock function:
- To activate the lock, press and hold the designated lock button (refer to your watch's specific button layout).
- A lock icon will typically appear on the display.
- To unlock, repeat the same button press and hold sequence.
The lock function is particularly useful for children or individuals who might inadvertently alter settings.
Maintenance
1. Cleaning
- Wipe the watch and band with a soft, damp cloth.
- Avoid using harsh chemicals or abrasive cleaners.
- Ensure the charging port is dry before charging.
2. Battery Care
- Charge the watch regularly to maintain battery health.
- Avoid fully depleting the battery frequently.
- If storing the watch for an extended period, charge it to about 50% and store in a cool, dry place.
3. Water Resistance
The e-vibra RL16 is designed for daily use and is resistant to splashes and sweat. However, it is not waterproof. Do not submerge the watch in water, wear it while swimming, or expose it to heavy rain or showers. Water ingress can damage the internal components.
Troubleshooting
