Setup

1. Battery Installation

  1. Locate the battery compartment cover on the back of the clock.

  4. Replace the battery compartment cover securely.

Note: An LR44 battery is typically included with your purchase.

2. Initial Power On and Radio Wave Reception

Upon battery installation, the clock will power on and automatically attempt to receive the time signal from the nearest atomic clock transmitter. This process may take several minutes to several hours depending on your location and environmental conditions.

  • Place the clock near a window, away from electronic devices that may cause interference.
  • The radio wave indicator on the display will flash during reception and become solid once synchronized.
  • If reception is poor, try repositioning the clock. Manual time setting is available if automatic synchronization is not successful.
