3. Setup

3.1 Battery Installation

1. Open the battery compartment cover located on the back of the clock (refer to Figure 2.2).
2. Insert two (2) AA alkaline batteries, ensuring correct polarity (+/-).
3. Close the battery compartment cover securely.

3.2 Initial Time Setting and Radio Reception

This clock is equipped with a radio reception function to automatically synchronize the time. For optimal reception, place the clock near a window or in an area with good signal strength.

Figure 3.1: Radio Wave Reception Feature
This diagram visually represents the 'Wave Ceptor' technology, indicating the clock's ability to receive radio signals for accurate time synchronization. It also shows the ON/OFF control for this feature.

• Automatic Reception: After battery installation, the clock will attempt to receive radio signals and set the time automatically. This process may take several minutes.
• Manual Reception: If automatic reception fails or you wish to initiate it manually, press and hold the 'RECEIVE' button (if present, or refer to specific button on back, typically labeled with a signal icon) until the hands start moving.
• Radio Wave Reception ON/OFF: Use the dedicated switch on the back of the clock to enable or disable the radio reception function. Disabling it will prevent automatic time synchronization, and you will need to set the time manually.
• Manual Time Adjustment (if radio reception is off or unavailable): Rotate the time setting knob (refer to Figure 2.2) to adjust the hour and minute hands to the correct time.

4. Operating Instructions

4.1 Setting the Alarm

1. Locate the alarm setting knob on the back of the clock (refer to Figure 2.2).
2. Rotate the alarm setting knob to move the small alarm hand to your desired alarm time.
3. Ensure the alarm ON/OFF switch (usually a small lever on the side or back) is in the 'ON' position.
4. The twin-bell alarm will sound at the set time.

4.2 Snooze Function

When the alarm sounds, press the large button located on the top of the clock (often integrated with the light button) to activate the snooze function. The alarm will temporarily stop and sound again after a few minutes (typically 5-10 minutes, depending on the model).

4.3 Using the Light

Press the light button (usually the same as the snooze button on top) to illuminate the clock face. The light features an afterglow function, meaning it will remain lit for a short period after the button is released, allowing you to read the time in the dark.

4.4 Second Hand Stop Function

When setting the alarm, the second hand will automatically stop moving. This feature helps in precisely setting the alarm time without distraction and conserves battery power during the alarm setting process.

5. Maintenance

• Cleaning: Wipe the clock with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the finish.
• Battery Replacement: Replace batteries promptly when the clock's functions (e.g., alarm, light) become weak or stop working. Always replace both batteries at the same time with new AA alkaline batteries.
• Storage: If storing the clock for an extended period, remove the batteries to prevent leakage and potential damage.

6. Troubleshooting

• Clock not keeping accurate time:
  • Check if the radio reception function is enabled.
  • Ensure the clock is in an area with good radio signal reception.
  • Replace batteries if they are low.
  • If radio reception is consistently poor, manually set the time.
• Alarm not sounding:
  • Verify that the alarm ON/OFF switch is in the 'ON' position.
  • Check battery level and replace if necessary.
  • Ensure the alarm hand is correctly set to the desired time.
• Light not working:
