Setup

1. Battery Installation

  1. Open the battery compartment cover on the back of the clock.
  2. Insert 2 x AA (LR6) batteries, ensuring correct polarity (+ and -).
  3. Close the battery compartment cover securely.

2. Initial Radio Signal Reception

Upon battery insertion, the clock will automatically attempt to receive the MSF radio time signal. This process may take a few minutes (typically less than 3 minutes). During this time, an antenna symbol will usually appear on the display, indicating it is searching for the signal. Once the signal is received, the clock will automatically set the correct time, date, and adjust for Daylight Saving Time (DST) if applicable.

If the clock does not set itself within a few minutes, try placing it near a window for better signal reception. Radio-controlled clocks can sometimes struggle to pick up signals in certain rooms or locations due to interference or building materials.

3. Radio Control Systems

This clock is designed for the UK and Ireland market, utilizing the MSF signal. For other regions, different radio control systems may be in use.

4. Manual Time/Date Adjustment (if needed)

In rare cases where the radio signal cannot be received, or if you wish to manually adjust certain settings, follow these steps:

  • To change 12h/24h display format: Press and hold the [Set] button until the display shows either '12h' or '24h'. Use the [▲] (Up) or [▼] (Down) buttons to toggle to your desired setting. Press [Set] again to confirm. Continue pressing [Set] a few more times until the clock returns to displaying the time.
  • Other manual settings (e.g., time zone, specific time/date) may be available by repeatedly pressing the [Set] button. Use the [▲] and [▼] buttons to adjust values.

Operating

Time Display

The clock displays hours, minutes, and seconds. It can be set to either a 12-hour format (with AM/PM indicator) or a 24-hour format.

Date and Day Display

The lower section of the display shows the current date (day and month) and the day of the week.

Temperature and Humidity Display

Maintenance

Cleaning

Antenna symbol is flashing or not displayed.Clock is searching for or has lost the radio signal.Ensure the clock is placed in an optimal location for signal reception (e.g., near a window, away from electronic interference). Allow several minutes for synchronization.
Temperature/Humidity readings seem inaccurate.Environmental factors or general indication.The temperature and humidity displays provide general indications and are not calibrated for scientific precision. Ensure the clock is not in direct sunlight or near heat/cold sources.
Alarm does not sound.Alarm is not activated or volume is too low (if adjustable).Ensure the alarm function is turned on (check for alarm icon on display). This model has a fixed alarm volume.
