2. Initial Setup and Radio Control Signal Reception

After battery installation, the clock will automatically begin searching for the radio control signal (MSF for UK and Ireland). This process may take several minutes. During this time, the radio control icon will flash on the display.

• Place the clock near a window for optimal signal reception.
• Avoid placing the clock near electronic devices that may cause interference (e.g., TVs, computers, microwaves).
• Once the signal is received, the time and date will set automatically, and the radio control icon will become solid.
• The clock automatically checks the time daily to ensure accuracy.

If the signal is not received after a few hours, try relocating the clock to a different position or manually setting the time (see "Manual Settings" section).

  • Allow several hours for the clock to receive the signal.
  • Manually set the time if the radio signal is consistently unavailable.
  • Verify you are in an MSF signal reception area (UK/Ireland).
• Temperature Reading Inaccurate:
  • Ensure the clock is not exposed to direct sunlight or heat sources, which can affect the sensor.
  • Allow time for the sensor to stabilize after moving the clock to a new environment.
• Alarm Not Sounding:
  • Check if the alarm is activated (alarm icon visible on display).
  • Ensure the alarm time is set correctly.
