The CH-899 handles DST automatically if you are in a region that observes it. But you must ensure:
If your clock changes at the wrong time (e.g., shifts at 1 AM instead of 2 AM), you may have the wrong time zone or DST offset setting.
Tips and Troubleshooting
Conclusion
Congratulations! You have successfully set up and configured your CH-899 Chouchin radio controlled clock. With its atomic accuracy and user-friendly interface, you'll never have to worry about keeping accurate time again. If you have any questions or issues, refer to the instructions or contact the manufacturer's customer support team. Enjoy your clock and experience the benefits of precise timekeeping!
To set up your Chouchin CH-899 radio controlled clock , you must first select your time zone and DST preference on the back of the movement, insert a fresh 1.5V AA battery, and then allow the hands to automatically fast-forward to the 12:00 position while the device searches for a time signal. The CH-899 movement, often identified as a sweep radio controlled mechanism, is designed to sync with atomic time signals like MSF or WWVB, ensuring accuracy within one second over millions of years. Initial Setup Instructions
Select Your Time Zone: Use the switches on the back to set your local time zone (e.g., P for Pacific, M for Mountain, C for Central, E for Eastern).
Toggle DST: Ensure the Daylight Savings Time (DST) switch is set to "ON" or "OFF" based on your local requirements.
Insert Battery: Place one new 1.5V AA alkaline battery into the compartment, noting the correct +/- polarity.
Automatic Synchronization: The hands will automatically advance to 12:00, 4:00, or 8:00 and stop. The clock is now in "set-up mode" and will search for a radio signal, which may take anywhere from a few minutes to several days. Manual Setting Procedures
If the clock cannot receive a signal in your location, you can set the time manually to use it as a standard quartz clock:
Entering Manual Mode: Press and hold the [M. SET] button for approximately 3 to 5 seconds until the hands begin to move. Adjusting Time:
Rapid Advance: Keep pressing the button to make the hands spin quickly.
Fine-Tuning: Release the button near the correct time, then press it repeatedly to advance the minute hand one minute at a time.
Saving Settings: Stop pressing the button for at least 7 seconds. The clock will exit manual mode and begin normal timekeeping. Force Signal Reception
If the clock is displaying the wrong time, you can manually trigger a search for the atomic signal: Press and hold the [REC] button for at least 3 seconds. ch-899 chouchin radio controlled clock instructions
The hands will return to the 12:00 position and begin a new search for the radio signal. Troubleshooting Tips
Signal Blockage: Place the clock near a window, preferably facing towards the signal source (e.g., Colorado for WWVB or Anthorn for MSF).
Interference: Keep the clock at least 6 feet (2 meters) away from electronic devices like TVs, computers, or microwaves.
Low Battery: If the hands spin randomly or the second hand moves in two-second increments, the battery is low and should be replaced.
Reset: For a hard reset, some CH-899 models have two pins on the movement that can be short-circuited with a metal object to clear the memory. MSF Radio Controlled Wall Clock - TLC Electrical Supplies
Setting up a Chouchin CH-899 radio-controlled (atomic) clock
ensures your timepiece is accurate to the second. This guide breaks down the simple steps to get your clock running perfectly, whether you're letting it sync automatically or need a quick manual adjustment. How to Set Your Chouchin CH-899 Clock
Setting up a radio-controlled clock is designed to be a "set it and forget it" process. Here is how to get started: 1. Initial Setup (Automatic Mode)
models are built to find the signal on their own once powered.
Select Your Time Zone: Before inserting the battery, locate the time zone switch on the back. Set it to P (Pacific), M (Mountain), C (Central), or E (Eastern).
Toggle DST: Ensure the Daylight Saving Time (DST) switch is set to ON if you want the clock to adjust itself twice a year.
Insert Battery: Pop in a fresh 1.5V AA alkaline battery (avoid rechargeables).
Wait for 12:00: After the battery is in, the hands will spin quickly and stop at the 12:00 position. The clock will stay there while it searches for the radio signal from Fort Collins, CO (WWVB).
Final Sync: This can take anywhere from a few minutes to a few days. It is highly recommended to set the clock near a window overnight, as the signal is strongest then. 2. Manual Time Setting
If you are in an area with poor reception or simply don't want to wait for the signal, you can set the time yourself: The CH-899 handles DST automatically if you are
Activate Manual Mode: Press and hold the M. SET button for about 3–5 seconds until the hands begin to move. Adjust the Time: Hold the M. SET button to make the hands spin rapidly.
Press and release the button to advance the minute hand by exactly one minute.
Save and Exit: Once you reach the correct time, release the button. If you don't press anything for about 7 seconds, the clock will lock in the time and start running normally. 3. Using the REC (Force Sync) Button
If your clock is showing the wrong time and you want it to try finding the signal immediately: Press and hold the REC button for 3 seconds.
The hands will return to the 12:00 position and begin searching for the atomic signal. If it fails, it will revert to the previous time. Troubleshooting Common Issues
Weak Signal: If the clock won't sync, move it away from electronics like TVs, computers, or microwaves, which can cause interference.
Wrong Time Zone: If the clock is exactly one or more hours off, double-check that your Time Zone switch on the back is in the correct position.
Stuck Hands: If the hands are twitching or not moving, try a Reset. Some models have a small reset hole you can press with a paperclip, or you can perform a "hard reset" by removing the battery for 10 minutes before trying again.
Need a replacement?If your movement has failed, you can find
replacement movements at retailers like Alibaba or through institutional suppliers like School Fix. If you’d like, let me know: Is your clock digital or analog? Are you having trouble with reception specifically? What state or region are you in? MSF Radio Controlled Wall Clock - TLC Electrical Supplies
The Chouchin CH-899 radio-controlled clock is designed to set itself automatically once a battery is inserted. It synchronizes with atomic time signals (such as MSF in the UK or WWVB in the US) to maintain high accuracy. Initial Setup (Automatic Mode)
Select Time Zone & DST: Before inserting the battery, set the Time Zone switch to your local zone (e.g., P, M, C, or E for Pacific, Mountain, Central, or Eastern) and ensure the DST switch is in the ON position if you live in an area that observes daylight saving.
Insert Battery: Place one fresh 1.5V AA alkaline battery into the compartment, noting the correct polarity (+/-).
Synchronization: The clock hands will quickly advance and stop at 12:00. The clock will then search for a signal, which can take a few minutes up to a few days depending on signal strength.
Tip: For best results, place the clock near a window overnight. Manual Time Setting If your clock changes at the wrong time (e
If you cannot receive a radio signal, you can set the time manually:
Press and hold the M. SET button for approximately 3 seconds.
Hold the button to trigger the hands into a fast-advance mode.
Release the button as you approach the correct time, then press it momentarily for 1-minute increments.
Exit: The clock will exit manual mode automatically if the button is not pressed for 7–8 seconds. Forced Signal Search To manually trigger a fresh search for the atomic signal: Press and hold the REC button for at least 3 seconds.
The hands will return to the 12:00 position and begin searching for a signal again. Troubleshooting
Wrong Time: If the clock shows the wrong time, ensure the Time Zone and DST switches were set before inserting the battery.
Interference: Keep the clock at least 2 meters away from TV sets, computers, or air conditioners that may cause signal interference.
Reset: To restart completely, remove the battery, wait at least 1 minute (or short-circuit the reset pins if available), and reinsert it.
Note for WiFi Versions: Some newer CH-899 movements use WiFi instead of radio signals. These require connecting to a mobile phone and entering a configuration page (typically 192.168.4.1) to set the SSID and password. MSF Radio Controlled Wall Clock - TLC Electrical Supplies
