Ch-899 Chouchin Radio Controlled Clock Instructions
The CH-899 is sensitive to interference. If it hasn't set after 15 minutes, move the clock.
Even with perfect instructions, problems happen. Here’s how to fix them:
If you live outside a signal coverage area or have persistent interference:
The CH-899 Chouchin radio-controlled clock is a precision timekeeping device designed to synchronize automatically with long-wave radio signals (such as the MSF in the UK or WWVB in the US) to maintain accuracy within one second in ten million years. Below are the comprehensive setup and operation instructions for this model. 1. Initial Setup and Automatic Synchronization
To begin, locate the controls on the back of the clock movement.
Select Settings: Before inserting the battery, set the Time Zone switch to your region (P for Pacific, M for Mountain, C for Central, E for Eastern). Ensure the DST (Daylight Savings Time) switch is in your preferred position.
Power On: Insert one fresh 1.5V AA Alkaline battery, observing the correct +/- polarity.
Auto-Calibration: Once powered, the hands will quickly advance and typically stop at the 12:00 position. The clock will then begin searching for the radio signal. This process can take between 3 to 10 minutes, though in some environments, it may take up to 24 hours to find a stable connection. 2. Manual Time Setting
If a radio signal is unavailable or you prefer a manual override:
Enter Manual Mode: Press and hold the M. SET button for approximately 3 seconds.
Adjust Time: Hold the button to make the hands advance quickly. For fine adjustments, a single press will advance the time by one minute.
Exit: Release the button once the correct time is reached. If no buttons are pressed for about 7 to 10 seconds, the clock will exit manual mode and resume normal operation. 3. Forced Signal Reception (REC)
If the clock is displaying the incorrect time, you can manually trigger a search for the atomic signal: ch-899 chouchin radio controlled clock instructions
Trigger Search: Press and hold the REC button for at least 3 seconds.
Scanning: The hands will return to 12:00 while the clock attempts to receive the signal. If successful, the hands will automatically adjust to the correct time. 4. Reset and Troubleshooting
If the clock becomes unresponsive or fails to sync, a factory restart may be necessary:
Resetting: Remove the battery for at least 15 minutes to clear the memory. Some variants may allow resetting by short-circuiting the pins in the upper-left corner of the movement.
Placement: For the best signal, place the clock near an exterior wall or window. Keep it at least 2 meters away from electronic interference like TVs or computers.
Low Battery Indicator: If the second hand begins advancing in 2-second increments, the battery is low and should be replaced immediately.

CH-899 Chouchin is a common radio-controlled (atomic) clock movement designed to synchronize automatically with time signals like Quick Setup Guide Insert Battery
: Place a fresh 1.5V AA alkaline battery into the compartment. Wait for 12:00
: Once powered, the hands will spin quickly and stop at the 12:00 position. Signal Search
: The clock will remain at 12:00 while it searches for a radio signal. This typically takes 3 to 10 minutes but can take up to 24 hours depending on signal strength. Automatic Set
: Once the signal is received, the hands will automatically advance to the correct time.

Are you the proud owner of a CH-899 Chouchin radio controlled clock? Congratulations on making a great choice! This atomic clock is designed to provide you with accurate timekeeping and a sleek, modern design. However, to get the most out of your clock, you need to understand how to set it up and use it properly. In this article, we'll provide you with a step-by-step guide on CH-899 Chouchin radio controlled clock instructions, so you can enjoy the benefits of this fantastic device.
Understanding the CH-899 Chouchin Radio Controlled Clock
Before we dive into the instructions, let's take a brief look at the features and benefits of the CH-899 Chouchin radio controlled clock.
CH-899 Chouchin Radio Controlled Clock Instructions
Now that we've covered the basics, let's move on to the instructions.
On many CH-899 clocks:
The CH-899 combines traditional analog or digital timekeeping with modern radio-controlled (RC) technology. It automatically synchronizes with a government radio time signal (like WWVB in the US, DCF77 in Europe, or MSF in the UK) to ensure perfect accuracy.
Once batteries are inserted, the CH-899 immediately attempts to receive the radio time signal. Here’s what happens:
Note: The CH-899 uses WWVB (60 kHz) in North America. In Europe, it uses DCF77 (77.5 kHz). The model is region-specific.
Many CH-899 models include an indoor thermometer (°C or °F). To toggle:
