Clock radio SENCOR SRC 3100 B — digital tuner FM, LED display, projection, AC/battery power

SENCOR SRC 3100 B is a compact clock radio with an FM digital tuner and a 0.9" (2.29 cm) amber monochrome LED display. Designed for bedside or desk use, it combines time projection, dual alarm functions and a range of user controls in a small black housing. The unit supports PLL FM reception across the 87.5–108 MHz band with up to 10 preset stations, and offers both mains operation and a CR2032 battery backup to preserve time and alarm settings during power interruptions.

Advantages

The clock radio provides a clear FM reception with preset memory for fast station access and a dimmable LED display for low-light environments. A red projection of the clock with a 180° rotating lens and adjustable focus allows viewing the time on a wall or ceiling. Dual alarm settings with selectable wake-up by buzzer or radio, plus sleep and snooze functions, make it suitable for typical household wake routines. Low power consumption and compact dimensions make it easy to place on a nightstand or small shelf.

Suitable for

• Bedroom bedside clock and alarm
• Home office or study desk clock
• Small apartments and travel where compact radio is needed
• Users who prefer FM radio wake-up or simple alarm features

How to use

Connect the unit to AC mains to power the radio and display. Set the time using the front-panel controls and tune the FM band to a desired station, saving it into one of the 10 preset slots for quick recall. Configure the two alarm times and choose whether each alarm should use the buzzer or the radio; enable snooze and sleep timer as needed. Insert a CR2032 battery in the backup compartment to keep time and alarm settings during power outages; the battery does not power normal operation.

Usage recommendations

Place the clock radio on a stable, level surface near an AC outlet and away from strong electromagnetic interference for best FM reception. Aim the projection lens toward a flat surface such as a wall or ceiling and adjust the lens rotation and focus to obtain a clear time image. Use the dimmer to reduce display brightness at night and check the CR2032 battery periodically to ensure alarm settings are retained during power loss.
