If the clock is showing wrong time after a battery change:
| Problem | Likely Cause | Solution | |--------|--------------|----------| | Clock does not set automatically | Weak signal | Move near a window, away from electronics. Force reception at night. | | Hands spin continuously | Batteries low or interference | Replace with new alkaline batteries. | | Clock is 1 hour fast/slow | DST setting incorrect | Check DST switch. If no switch, manually set and allow overnight sync. | | Second hand stops but others move | Low battery | Replace batteries immediately. | | Clock shows wrong time after battery change | Internal reset failed | Remove batteries for 10 minutes, then reinstall. |

To set up your Chouchin CH-899 radio controlled clock , follow these steps for automatic or manual synchronization. Automatic Setup
This is the recommended method to ensure your clock remains perfectly synchronized with the atomic signal. Set Time Zone & DST
: Before inserting the battery, locate the switches on the back. Slide the switch to your location ( -Mountain, -Eastern). Set the
switch to "ON" if you want the clock to adjust for Daylight Savings automatically. Insert Battery : Place one fresh AA alkaline battery into the compartment, observing the correct polarity (+/-). Synchronization Phase : The hands will quickly advance to the 12:00 position and stop. The clock will now search for the radio signal. : Signal reception typically takes 3 to 15 minutes
but can take up to several hours or overnight in areas with poor reception. Place the clock near a window, preferably facing Colorado (for the WWVB signal), to improve success. School Fix Manual Time Setting If the clock cannot find a signal, you can set it manually: Enter Manual Mode : Press and hold the button for approximately 3 seconds. Adjust Time : Continue holding the
button to make the hands move rapidly. Release the button as you approach the correct time, then press and release it repeatedly to advance the hands one minute at a time for precise adjustment.
: Stop pressing the button for about 6–10 seconds to save your setting and return to normal timekeeping. TLC Electrical Supplies Troubleshooting Force Signal Search : If the time is incorrect, press and hold the
(or WAVE) button for 3 seconds. The hands will reset to 12:00 and begin a fresh signal search. Hard Reset
: If the clock is unresponsive, remove the battery and wait at least 10 seconds (or insert the battery backward for 10 seconds to clear the memory) before reinserting it correctly. Low Battery
: If the minute hand starts moving in 2-second increments, it is time to replace the battery.

The Chouchin CH899 radio-controlled clock is designed to automatically sync with the atomic time signal. Most issues with these clocks arise during the initial setup or from signal interference. Quick Setup Guide
Set Your Time Zone: Locate the time zone switch on the back. Choose your region (P = Pacific, M = Mountain, C = Central, E = Eastern).
Toggle DST: Ensure the DST (Daylight Saving Time) switch is set to "On" if you want the clock to adjust itself twice a year.
Insert Battery: Use one fresh 1.5V AA Alkaline battery. Avoid rechargeable batteries, as they often lack the consistent voltage needed for the signal receiver.
Wait for Sync: Once the battery is in, the hands will usually fast-forward to 12:00 and stop. It will stay there while it searches for a signal, which can take anywhere from 5 minutes to several days. Manual Time Setting
If you are in an area with poor reception (like a basement or metal building), you can set the time yourself:
Manual Mode: Press and hold the M.SET button for about 3 seconds.
Adjusting: Once the hands start moving, hold the button to advance them quickly. Tap the button for one-minute increments.
Locking In: Stop pressing and wait about 7–10 seconds; the clock will exit manual mode and begin running normally. Troubleshooting & Tips Atomic Clock Instructions - School Fix

Unfortunately, I couldn't find a free, downloadable instruction manual for the CH899 Chouchin radio-controlled clock. However, these general guidelines should help you set up and use your clock.
If you're still having trouble, you can:
The CH899 Chouchin radio-controlled clock is designed to synchronize automatically with atomic time signals (such as MSF in the UK or WWVB in the US) to maintain extreme accuracy. Initial Setup (Automatic Setting)
Select Time Zone: Set the Time Zone switch on the back to your local zone (e.g., P for Pacific, M for Mountain, C for Central, E for Eastern).
DST Setting: Ensure the Daylight Savings Time (DST) switch is set to "ON" unless you live in an area that does not observe it.
Insert Battery: Place one fresh 1.5V AA alkaline battery into the compartment, noting the correct polarity (+/-).
Wait for 12:00: Upon battery insertion, the hands will fast-forward and stop at the 12:00 position. The clock will stay here for 3–10 minutes while searching for a signal. | Problem | Likely Cause | Solution |
Signal Acquisition: Once the signal is found, the hands will automatically move to the correct time. Manual Controls
Manual Time Set: Press and hold the M.SET button for 3 seconds. Once the hands start moving, continue holding or pulse the button to advance the time by one minute per press.
Forced Signal Search: To manually trigger a search (e.g., if the time is wrong), press and hold the REC button for 3 seconds. The hands will return to 12:00 to begin searching.
Reset: If the clock becomes unresponsive, you can perform a hard reset by briefly short-circuiting the two small metal pins in the upper left corner of the movement. Tips for Best Performance
Placement: For the best signal, place the clock near a west-facing window or away from electronic interference like TVs and computers.
Nighttime Sync: Signals are often strongest at night. If the clock doesn't set immediately, leave it overnight near a window.
Low Battery Warning: If you notice the hands spinning randomly or the second hand moving in two-second jumps, it is time to replace the battery. MSF Radio Controlled Wall Clock - TLC Electrical Supplies
