2. セットアップと初期操作
2.1 バッテリーの取り付け
- 目覚まし時計の背面にある電池ケースのカバーを見つけます。
- カバーを取り外します。
- Insert one (1) AA / LR6 battery, ensuring the correct polarity (+/-) as indicated inside the compartment.
- 電池収納部のカバーをしっかりと取り付けてください。
2.2自動時刻設定
Upon battery insertion, the alarm clock will automatically begin the time synchronization process.
- The clock hands will first perform a full rotation and then stop precisely at the '12' position.
- The alarm clock will then enter reception mode to synchronize with the DCF-77 time signal.
- 重要: This initial synchronization can take up to 20 minutes. During this period, the hands may not move. Do not interrupt this process, as it will restart if disturbed. Patience is required for successful initial setup.
- Once synchronized, the hands will automatically move to display the correct time.
3. 操作手順
3.1アラームの設定
- 時計の背面にあるアラーム設定ノブを見つけます。
- Rotate the knob to set the desired alarm time.
- To activate the alarm, slide the alarm switch (located on the right side of the casing) to the "ON" position.
- When the alarm is activated, the second hand will move to the '12' position after approximately 2 minutes and stop, enabling the "No Tick" silent function.
3.2スヌーズ機能
When the alarm sounds, press the large button located on the top of the alarm clock. This will pause the alarm for approximately 5 minutes. The alarm will sound again after this period.
3.3 Dial Illumination
To temporarily illuminate the dial, press the same large button on the top of the alarm clock. Release the button to turn off the illumination.
3.4 Automatic Daylight Saving Time (DST) Adjustment
The alarm clock automatically adjusts for Daylight Saving Time (summer/winter time) changes. This adjustment occurs unnoticed overnight between 2 AM and 3 AM.
4. お手入れとメンテナンス
- Clean the alarm clock with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- 時計を極端な温度、直射日光、高湿度にさらさないでください。
- Replace the battery annually or when the clock's functions (e.g., alarm, illumination) become weak. Always use a fresh AA / LR6 battery.
- Do not attempt to disassemble the alarm clock, as this may void any potential warranty and cause damage.
5。 トラブルシューティング
| 問題 | 考えられる原因 | 解決 |
