Radio-controlled clocks offer unparalleled timekeeping accuracy by synchronizing with atomic clock radio signals. The CH-899 Chouchin clock movement is a popular, reliable mechanism used in many wall and desk clocks globally. However, losing the physical manual can make setting up or troubleshooting this precise device frustrating.
The clock will spend the next 10–15 minutes trying to acquire the radio signal.
The CH-899 movement is designed for high energy efficiency, often lasting up to 1 year on a single AA battery. It is highly recommended to use high-quality alkaline batteries to avoid leakage, which can damage the delicate radio circuitry.
Once the batteries are installed, the display will light up, and the clock will display 12:00 or a default time, immediately attempting to search for the radio signal. 2.2. Automatic Time Setting (RCC)

Before you look for the atomic signal, let’s get the clock physically ready.
When you first receive your clock, you might notice the hands are not all pointing at 12 o’clock. Before you do anything else, rotate the hands on their shaft until they are all pointing precisely at 12. This ensures the internal gears are correctly aligned.
Here are some frequently asked questions about the CH-899 Chouchin Radio Controlled Clock:
(or sometimes 4:00 or 8:00) while the clock searches for a signal. This process typically takes 3–10 minutes but can take up to several days in poor reception areas. School Fix Manual Time Setting The clock will spend the next 10–15 minutes
Press and hold the button for about 3 seconds to enter manual mode. Hold the button down to make the hands advance quickly. Release the button when you are close to the correct time.
: A physical switch on the back allows users to select between Pacific (P), Mountain (M), Central (C), and Eastern (E) time zones. TLC Electrical Supplies Key Features and Performance Atomic Clock Instructions - School Fix
1.5V AA Alkaline batteries (Typically 1 or 2 required)
This indicates the clock has successfully received the time signal, but the internal time zone setting is incorrect. If your specific version of the CH-899 features time zone switches, ensure it matches your region (e.g., PT, MT, CT, ET). The clock loses a few minutes every day Once the batteries are installed, the display will
Once batteries are inserted, you will observe one of two behaviors:
The back of the CH-899 movement features several tactile buttons. Understanding their layout replaces the need for a printed manual sheet.
Forces the clock to look for a radio signal immediately, rather than waiting for its scheduled nighttime sync.
