Product Overview
The Seiko Clocks QHR201S is a compact, modern analog alarm clock designed for clarity and ease of use. Its radio wave control feature ensures precise timekeeping.

Key components include the analog dial for time display, control knobs/buttons (typically on the back or side) for setting time and alarm, and a top button for backlight activation and snooze function.
Setup
1. Battery Installation
- Locate the battery compartment cover on the back of the clock.
- Remove the cover by sliding or lifting it.
- Insert one AA battery, ensuring the positive (+) and negative (-) terminals align correctly with the markings inside the compartment.
- Replace the battery compartment cover securely.
2. Initial Time Setting (Radio Wave Control)
Upon battery installation, the clock will automatically attempt to receive the radio time signal. This process may take several minutes to an hour, depending on your location and signal strength. During this time, the hands may move rapidly until the correct time is set.
- Place the clock near a window for better signal reception.
- Avoid placing the clock near electronic devices that may cause interference.
- Once the signal is received, the clock will automatically adjust to the correct local time, including daylight saving time changes.
Operating Instructions
Setting the Alarm
- Locate the alarm setting knob, usually on the back of the clock.
- Rotate the knob to move the alarm hand to your desired alarm time.
- Locate the alarm ON/OFF switch (often a small slider or button). Set it to the ON position to activate the alarm.
Using the Backlight
Press the button located on the top right of the clock casing to activate the backlight. The backlight will illuminate the dial for a few seconds, allowing you to read the time in low-light conditions.
Snooze Function
When the alarm sounds, press the top button to activate the snooze function. The alarm will temporarily stop and sound again after a few minutes (typically 5-10 minutes).
Stopping the Alarm
To completely stop the alarm, move the alarm ON/OFF switch to the OFF position.
Maintenance
Cleaning
Wipe the clock's casing with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the finish.
Battery Replacement
Replace the AA battery when the clock's display becomes dim, the backlight weakens, or the clock stops functioning. Follow the battery installation steps outlined in the Setup section.
Troubleshooting
- Clock not displaying correct time: Ensure the battery is correctly installed and has sufficient power. Allow time for the radio wave signal to be received. Try moving the clock to a different location, preferably near a window.
- Alarm not sounding: Check that the alarm ON/OFF switch is in the ON position. Verify that the alarm time is set correctly.
- Backlight not working: Replace the battery if it is low. Ensure the top button is being pressed firmly.
- No radio signal reception: Ensure the clock is not near sources of interference (e.g., TVs, computers, large metal objects). Try repositioning the clock.
