Setup
1. Unpacking
- Carefully remove the clock from its packaging.
- Inspect the clock for any signs of damage.
- Retain all packaging materials for future transport or service.
2. Battery Installation
The clock requires batteries for operation (not included). Locate the battery compartment, typically on the back of the clock or behind the dial access panel. Insert the required number and type of batteries, ensuring correct polarity (+/-).
3. Mounting the Clock
This clock is designed for wall mounting. Choose a sturdy location on a wall, away from direct sunlight or extreme temperature changes. Use appropriate wall anchors and screws to securely hang the clock. Ensure the clock is level to allow the pendulum to swing freely.
4. Setting the Time
- Locate the time-setting knob or hand-setting mechanism, usually on the back of the movement or accessible from the front.
- Gently turn the minute hand clockwise to set the correct time. Do not move the hour hand directly.
- Allow the clock to chime at each quarter hour or hour as you advance the time.
5. Chime Settings
Your clock features a triple-chime Harmonic movement. Controls for chime selection, volume, and nighttime shut-off are typically located on the back of the movement or within the battery compartment area.
- Chime Selection: Use the selector switch to choose between Westminster, Ave Maria, or Bim Bam melodies.
- Volume Control: Adjust the volume dial or switch to your preferred chime loudness.
- Nighttime Shut-off: Activate the automatic nighttime shut-off feature to silence the chimes during specific hours (e.g., 10 PM to 7 AM). Refer to the specific markings on your clock's movement for exact settings.
Operating Instructions
Daily Operation
Once set up, the clock will operate continuously as long as the batteries provide power. The pendulum will swing, and the hands will advance, indicating the current time.
Chime Operation
The selected chime melody will play on the quarter-hour, half-hour, three-quarter hour, and on the hour. On the hour, the full melody will play, followed by the appropriate number of strikes for the hour. If the nighttime shut-off is activated, chimes will be suppressed during the programmed period.
Maintenance
Cleaning
- Wood Case: Dust the wood case regularly with a soft, dry cloth. For a deeper clean, use a furniture polish specifically designed for wood finishes, following the product instructions. Avoid abrasive cleaners.
- Dial and Glass: Gently wipe the dial and glass with a soft, lint-free cloth. If necessary, slightly dampen the cloth with water or a mild glass cleaner, but avoid spraying directly onto the clock.
- Metal Components: Polish nickel-finished components with a soft cloth. Avoid harsh chemicals that could damage the finish.
Battery Replacement
Replace all batteries annually or when the clock's operation becomes erratic, such as slowing down, chimes weakening, or stopping entirely. Always replace all batteries at the same time with new, high-quality batteries of the specified type.
Troubleshooting
- Clock Not Running:
- Check if batteries are installed correctly with proper polarity.
- Replace old batteries with new ones.
- Ensure the pendulum is swinging freely and not obstructed.
- Chimes Not Working:
- Verify that the chime volume is not set to minimum or off.
- Check if the nighttime shut-off feature is active during the current time.
- Ensure batteries are fresh.
- Incorrect Time or Chime Synchronization:
- Reset the time by advancing the minute hand clockwise until the correct time is displayed and the chimes synchronize with the hour.
- If the clock is consistently fast or slow, consult the manufacturer's support for potential adjustment instructions.
