4. メンテナンス
Proper care of your Fitbit Blaze ensures its longevity and maintains skin comfort.
4.1 クリーニング
- 特に運動後や発汗後は、バンドと手首を定期的に清潔にしてください。
- バンドを水で洗い流すか、少量の消毒用アルコールで拭いてください。
- 使ってはいけません hand soap, body soap, dish soap, hand sanitizers, cleaning wipes, or household cleaners, as these can irritate skin or damage the device.
- バンドを再び装着する前に必ず完全に乾かしてください。
4.2 Keeping it Dry
While Fitbit devices are water-resistant (IPX4 rating), it is not recommended to wear a wet band for extended periods. If your elastomer band gets wet, rinse and dry it thoroughly before re-wearing. Ensure your skin is dry before putting the band back on.
4.3 適切なフィット
- Do not wear the band too tightly. It should be loose enough to move back and forth on your wrist.
- For accurate PurePulse Heart Rate readings during exercise, wear the band securely (but not too tight) and higher on your wrist (about 2-3 finger widths above your wrist bone). Lower and loosen the band after exercise.
4.4 皮膚刺激
Prolonged rubbing and pressure may irritate the skin. Give your wrist a break by removing the band for an hour after extended wear. If you experience redness or skin irritation, remove your device. If symptoms persist for more than 2-3 days of not using your device, consult a dermatologist.
5。 トラブルシューティング
If you encounter issues with your Fitbit Blaze, consider the following common solutions:
- 同期の問題: Ensure Bluetooth is enabled on your smartphone/computer and the Fitbit app is open. Check that your device is within the syncing range (up to 6.1 meters).
- バッテリー寿命: If battery life is shorter than expected, ensure notifications are not excessively frequent and that the device is fully charged.
- 心拍数の不正確さ: Ensure the device is worn correctly (snug but not too tight, higher on the wrist during exercise). Clean the sensor regularly.
- 画面の応答性: Restart the device if the touchscreen becomes unresponsive.
