3. Mounting the Clock
This clock is designed for wall mounting. Use a sturdy screw or hook appropriate for the clock's weight (approximately 9 pounds) and the wall material. The clock features a built-in mounting bracket on the back.
- Select a suitable location on a wall.
- Install a wall anchor and screw, leaving a small portion of the screw head exposed.
- Carefully hang the clock onto the screw using the mounting bracket. Ensure it is level and secure.
Operating Instructions
1. Setting the Time
- Gently turn the minute hand clockwise to set the correct time. Do not turn the hour hand directly.
- Allow the clock to chime at each hour or quarter hour as you advance the time.
2. Chime Settings
Your Seiko QXH039BLH clock offers dual chimes (Westminster and Whittington), volume control, and an automatic nighttime silencer.
- Chime Selection: A switch or dial on the clock's movement (often accessible from the back or by opening the front door) allows you to select between Westminster and Whittington chimes. Refer to the markings near the control for specific options.
- Volume Control: A volume dial or slider is provided to adjust the chime loudness. Turn the dial to increase or decrease the volume to your preference.
- Nighttime Silencer: The clock features an automatic nighttime silencer, which typically mutes the chimes between 11:00 PM and 5:45 AM to ensure quiet during sleeping hours. This feature is automatic and generally does not require manual adjustment.
- Quarter Hour Chimes: This model chimes on the quarter hour, with hourly strikes following the hourly chime. Please note that there is no option to disable the quarter-hour chimes independently while keeping the hourly chimes active.
Maintenance
1. Cleaning
To clean the clock, wipe the wooden case with a soft, dry cloth. For the glass, use a glass cleaner sprayed onto a cloth, not directly onto the clock, to avoid liquid seeping into the mechanism.
2. Battery Replacement
Replace the C battery annually or when the clock's timekeeping becomes inaccurate, the chimes weaken, or the pendulum stops swinging. Follow the battery installation steps outlined in the Setup section.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Clock not running / Pendulum not swinging | Dead or incorrectly installed battery; Pendulum mechanism obstructed. | Replace battery, ensuring correct polarity. Check if any shipping material is still attached to the pendulum. Ensure pendulum is properly hooked. |
| Chimes are too loud or too quiet | Volume setting is incorrect. | Adjust the volume control dial/slider. |
| Chimes not sounding at night | Automatic nighttime silencer is active. | This is normal operation. Chimes will resume in the morning. |
| Chimes are incorrect or out of sync with time | Time was set incorrectly or clock was moved. | Advance the minute hand clockwise to the correct time, allowing the clock to chime naturally. |
| Clock loses or gains time | Weak battery; Environmental factors. | Replace the battery. Ensure the clock is not exposed to extreme temperatures or humidity. |
