While your CH-899 is designed to set itself automatically, there are scenarios where you might want (or need) to set the time manually. For example, you might be in a remote location with weak radio signal, or you might want to use the clock immediately.
Dust the exterior casing with a dry microfiber cloth. Never spray liquid cleaners or water directly onto the back movement housing.
The is a high-precision timepiece designed to synchronize automatically with atomic clock signals. Whether you are setting it up for the first time or troubleshooting a signal issue, this manual provides the necessary steps for both automatic and manual operation. Quick Setup Guide (Automatic Setting)
What the clock is showing right now (e.g., hands not moving, wrong time zone)? Does your clock have additional switches on the back? ch-899 chouchin radio controlled clock manual
If the clock fails to receive a signal during one of these scheduled times, it will try again during the next scheduled window. If the clock has not received a signal for a prolonged period, it may also attempt to sync during the day.
The hour and minute digits will flash. Adjust them to your current local time, pressing after each entry to save.

The clock will now remain stationary at 12:00 while it searches for the atomic radio broadcast. during this time. Signal acquisition can take anywhere from 3 to 15 minutes .
Do not hang the clock on metal walls or inside structures with heavy steel framing, as this acts as a Faraday cage and blocks radio waves.
Radio signals can be disrupted by electronics or structural obstacles. For the best connection:
