Digital alarm clock Hama RC 660

The Hama RC 660 is a compact digital alarm clock in white with a clear LED display and white backlight. It runs on AAA (Micro) batteries and has a compact footprint (118 × 65 × 40 mm), making it suitable for bedside use. The clock receives DCF time signals and adjusts automatically to the world's most accurate time source, simplifying setup and ensuring correct timekeeping.

Advantages

Two independently programmable alarm times allow different wake-up schedules for two people or for separate morning routines. The alarms can be configured as weekday-only (Monday to Friday). An integrated light sensor with an on/off option activates the backlight automatically in the dark, improving readability at night while preserving battery life when ambient light is sufficient.

Suitable for

• Bedside alarm clock for home bedrooms
• Travel use where compact size and battery power are needed
• Users who prefer automatic time synchronization via DCF
• Situations requiring two different alarm times or weekday-only alarms

Usage recommendations

For best DCF reception, position the clock away from large metal objects and electronic devices that can cause interference; near a window usually improves signal quality. Replace batteries when the display becomes dim or alarms sound weak to maintain reliable operation.
