Maintenance

• Clean the clock's display and casing with a soft, dry cloth. Avoid abrasive cleaners or solvents.
• Replace batteries when the display dims or functions become erratic. Always replace all batteries at once with new ones of the same type.

Troubleshooting

No Display or Erratic Behavior

Issue: The display is blank or showing incorrect information.

Solution:

• Check battery installation and ensure polarity is correct.
• Replace old batteries with new ones.
• If the clock stops working or buttons cease to function, perform a reset. Locate the small reset button (often a small recessed hole) on the back of the clock and press it with a toothpick or a thin, non-metallic object.

Atomic Time Signal Issues

Issue: The clock is not synchronizing with the atomic time signal or shows an incorrect time.

Solution:

• Ensure the clock is placed in an area with good signal reception, away from electronic interference (e.g., TVs, computers, large metal structures).
• Try repositioning the clock to a different location.
• Allow sufficient time (up to 24 hours) for the clock to receive the signal, especially during initial setup or after battery replacement.
• Verify the correct time zone is selected using the PMCE switch on the back.

Backlight Not Working

Issue: The backlight does not illuminate.
