The CH-899 utilizes a radio receiver to pick up time signals, typically MSF (UK) or DCF (Germany/Europe), to update the time automatically. It includes a radio-controlled movement designed for stability and accuracy. 1 x AA / LR6 Alkaline battery (1.5V).
Radio-controlled clocks offer perfect timekeeping by synchronizing with atomic time signals. The CH-899 Chouchin clock movement is a popular, reliable mechanism used in many wall clocks.
If the time is wrong and you want it to try syncing again right now , press and hold the [REC] or [WAVE] button for 3 seconds. The hands will return to 12:00 and begin a fresh search.
Closing note The CH-899 Chouchin is intended for low-maintenance, accurate timekeeping when placed where it can receive the regional time signal. If you need a copy of the original manual, check the sellerβs website or request a PDF from the manufacturer.
Press and hold the [REC] button for at least 3 seconds . ch-899 chouchin radio controlled clock instructions
The hands will stop exactly at the 12:00 position (or 4:00 / 8:00 on certain sub-versions) to enter signal reception mode.
The hands will automatically stop at exactly 12:00, 4:00, or 8:00. This is the baseline positioning phase.
Use the reset function if the clock hands become desynchronized from the actual time, or if the internal microprocessor locks up:
The 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 The CH-899 utilizes a radio receiver to pick
Hanging the clock on metal surfaces or inside buildings with heavy steel reinforcement will severely degrade radio signal reception.
Wait up to 15 minutes. If it does not move, the signal strength is too weak. Move the clock near a window and press the RESET button. The clock displays the wrong hour (Time Zone Issue)
As the night deepened, the storm broke. The clouds tore apart, revealing a bruised, purple sky. The moonlight filtered through the window, striking the face of the Chouchin.
Although your CH-899 is a radio-controlled clock, there are times when you might need to set the time by hand, such as when replacing batteries or if the radio signal is temporarily unavailable. This process varies slightly between models: The hands will return to 12:00 and begin a fresh search
The hands are moving to their start position.
If the clock fails to find a signal within 15 minutes, it will start running from the 12:00 position like a standard quartz clock. If this happens, leave it overnight, as radio signals are stronger in the dark. Manual Time Setting
The CH-899 is designed to set itself once the battery is inserted.
: If no buttons are pressed for about 7β10 seconds , the clock will save the time and resume normal operation. Advanced Functions
The "CH-899" is not the model of a single clock, but rather the identifier for the quartz movement inside. "Chouchin" (ζη―) is a Japanese word for a traditional paper lantern, and the CH-899 movement is often used in beautifully designed clocks that blend modern functionality with aesthetic appeal.
It uses standard batteries but relies on microprocessors to spin the hands automatically to the correct position. Step-by-Step Initial Setup Instructions
