TLC Electrical Supplies Troubleshooting & Maintenance Howard Miller Radio Controlled Clock Operating Instructions
Setting up and maintaining the Chouchin CH-899 radio-controlled clock (also known as an atomic clock) ensures you never have to manually adjust for daylight savings or drift again. This clock uses a high-precision radio signal (MSF in the UK or WWVB in North America) to synchronize its time. Initial Setup Instructions
For the most accurate results, perform the setup near a window, ideally at night when radio signals are strongest.
Select Your Time Zone: Before inserting batteries, locate the Time Zone switch on the back. Choose your zone: P (Pacific), M (Mountain), C (Central), or E (Eastern).
Toggle DST: Ensure the DST (Daylight Savings Time) switch is set to "ON" if your region observes it.
Insert Battery: Place one fresh 1.5V AA alkaline battery into the compartment, following the +/- polarity markings. Do not use rechargeable batteries.
Automatic Synchronization: Once powered, the hands will rapidly advance to the 12:00 position and stop. The clock will then search for a signal, which can take anywhere from a few minutes to several hours (and sometimes overnight). Manual Time Setting
If you are in an area with poor signal reception, you can set the time manually until the clock manages to sync.
Entering Manual Mode: Press and hold the M. SET (Manual Set) button for approximately 3 seconds. Adjusting Time:
Rapid Advance: Keep holding the M. SET button to make the hands move quickly. If you have lost your original printed manual,
Incremental Advance: Release the button and press it briefly to move the time forward by one minute at a time.
Exiting: Stop pressing the button for about 7–8 seconds. The clock will exit manual mode and begin running normally. Troubleshooting & Maintenance
Force Signal Search: If the clock displays the wrong time, press and hold the REC (Receive) button for 3 seconds. The hands will return to 12:00 to restart the search.
Full Reset: If the movement becomes unresponsive, use a paperclip to short-circuit the Reset pins (small holes located near the upper-left corner of the movement). This clears the clock's memory and restarts the 12:00 alignment.
Signal Interference: Keep the clock at least 2 meters away from electronics like TVs, routers, or computers, as these can block the radio signal.
Low Battery Warning: If the second hand begins jumping in 2-second increments, it is time to replace the battery.
Note on Wi-Fi Models: Some CH-899 variants use Wi-Fi instead of radio signals. For these, you must connect to the clock's internal network (often named "Accue_XXXXXX") via a smartphone and access the setup page at 192.168.4.1 in your browser to configure your home Wi-Fi.

To set up your Chouchin CH-899 Radio Controlled Clock, follow these steps according to the Atomic Clock Instructions and TLC Electrical Supplies data sheets. Automatic Setup
Set Time Zone: Slide the switch to your local time zone (P for Pacific, M for Mountain, C for Central, E for Eastern).
Insert Battery: Insert one fresh 1.5V AA Alkaline battery. Ensure the polarity (+/-) matches the markings. Need further assistance
Position the Clock: Place the clock near a window, ideally facing Colorado (for WWVB signals in the US) or towards the transmitter in your region.
