Ch-899 Chouchin Radio Controlled Clock Manual -

The CH-899 is a self-setting digital or analog clock (typically a large display digital model) that synchronizes with a national time signal (e.g., DCF-77 in Europe, WWVB in the US, or MSF in the UK). It automatically adjusts for daylight saving time (DST) and leap years.

  • Manual Signal Search: Press and hold the UP (+) button for 3–5 seconds. The clock’s second hand should jump to a position indicating it’s searching (often “RX” or the clock icon will flash).
  • Walk away. It takes 2 to 10 minutes to catch the signal. Do not press buttons during this time.

    • If the clock displays the wrong time or the antenna icon is flashing continuously, force a manual sync.

    Q: Does the CH-899 work worldwide? A: No. Radio-controlled clocks are region-specific. The CH-899 typically receives the WWVB signal (60 kHz) for North America or DCF77 (77.5 kHz) for Europe. Check your user manual or product listing for your region. Manual Signal Search: Press and hold the UP

    Q: Why is there no "CH-899 Chouchin radio controlled clock manual" paper in the box? A: Many manufacturers now provide a QR code on the packaging leading to a digital manual. This guide contains the essential information from that manual.

    Q: Can I silence the second hand? A: Most CH-899 models have a continuous sweep second hand (silent). If yours ticks loudly, look for a "Silent" switch on the back. Not all models support this.

    Q: What does it mean when the clock hands spin continuously? A: This is the "fast forward" mode, usually triggered after a RESET or new battery insertion. The clock is calibrating its gear positions. It will stop at 12:00 automatically.
