If the clock does not immediately seek the signal, it may need a manual orientation.

| Icon | Meaning | |------|---------| | Flashing tower | Searching for signal | | Solid tower | Connected / last sync successful (usually within 24h) | | No tower | No recent reception (manual setting needed) |

Once the clock is at 12:00, the clock should automatically begin searching for the signal.

CHOUCHIN CH-899 is a precision radio-controlled (RC) clock movement designed to synchronize with atomic time signals (like MSF in the UK, WWVB in the US, or DCF in Europe). TLC Electrical Supplies Initial Setup (Automatic Setting) Preparation ch-899 chouchin radio controlled clock instructions

: If your clock has a back cover, remove it to access the movement. Time Zone/DST : If your model has switches, set your (P, M, C, E) and

(Daylight Saving Time) to the "ON" position before inserting the battery. Battery Insertion : Insert one fresh 1.5V AA alkaline battery , observing the correct polarity (+/-). Calibration : The hands will automatically spin and stop at (this can take 1–6 minutes). Signal Search

: Once at 12:00, the clock stays still while searching for a radio signal. This usually takes 4–10 minutes

. If a signal is found, the hands will fast-forward to the correct time. TLC Electrical Supplies Manual Time Setting Use this if you are out of range of a radio signal: Press and hold the button for about until the hands start moving. Fast Forward : Continue holding the button to advance the hands quickly. Fine Adjustment

: Release the button near the desired time, then press it momentarily for 1-minute increments. : Stop pressing the button. If no buttons are pressed for 7–8 seconds , the clock exits manual mode and starts running. TLC Electrical Supplies Manual Signal Reception (Forced Sync) If the time is inaccurate, you can force a new search: Press and hold the (or Wave) button for

The hands will return to 12:00 and begin searching for a signal again. TLC Electrical Supplies Troubleshooting Tips MSF Radio Controlled Wall Clock - TLC Electrical Supplies Radio controlled clocks need a clear path to the transmitter

To set up your Chouchin CH-899 radio-controlled clock, follow these standard steps for both automatic and manual synchronization. Automatic Setup

For the most accurate results, let the clock find the radio signal automatically:

Configure Switches: Before inserting the battery, set the Time Zone switch to your location (P-Pacific, M-Mountain, C-Central, E-Eastern) and ensure the DST (Daylight Savings Time) switch is set to "ON".

Insert Battery: Place one fresh 1.5V AA alkaline battery into the compartment.

Wait for 12:00: The hands will quickly advance and stop exactly at 12:00. The clock is now in "reception mode" and searching for the WWVB signal.

Signal Search: It can take from a few minutes up to a few days to catch the signal. It is best to place the clock near a window, preferably facing Colorado (the signal source), overnight. Manual Time Setting Solutions: Solutions: If the clock does not immediately

If you are in a weak signal area and the hands remain at 12:00:

Enter Manual Mode: Press and hold the M. SET button for approximately 3 seconds. Advance Hands: Hold the button to make the hands advance quickly.

Press and release the button to move the minute hand forward by exactly one minute.

Save Settings: Once you reach the correct time, release the button. If no buttons are pressed for about 7 seconds, the clock will exit manual mode and begin running as a standard quartz clock. Troubleshooting & Forced Signal Search

Forced Reception: If the clock shows the wrong time, press and hold the REC button for 3 seconds. The hands will return to 12:00 and start a fresh signal search.

Low Battery Signal: If the hands start spinning randomly or move in 2-second jumps, it usually indicates the battery is low and needs replacement.

Hard Reset: If the clock is unresponsive, remove the battery and wait at least one minute (some experts suggest pressing the reset button 20 times while the battery is out) before reinserting it. MSF Radio Controlled Wall Clock - TLC Electrical Supplies
