Sharp SPC483 Digital Alarm Clock Blue 4.0 x 3.81 x 2.3 in

Sharp SPC483 Digital Alarm Clock

The Sharp SPC483 is a compact digital alarm clock with a tactile rubberised blue finish. Battery power and top-mounted controls make it simple to set up on any bedside table, desk or shelf without needing a mains socket. Its large 1-inch LCD display remains clear across a room, suiting adults and children who want a straightforward wake-up device.

Check power and placement before ordering

The clock runs on two AAA batteries which are not supplied, so have a fresh pair ready for first use. Verify that the 4.0 by 3.81 by 2.3 inch footprint fits your chosen surface and that the blue colour matches your decor. Because there is no mains adapter, confirm you are comfortable replacing batteries periodically rather than relying on continuous wall power.

Thermals noise and power in normal use

Battery operation means the unit produces no audible fan noise and generates negligible heat during everyday use. The blue backlight activates only when the snooze button is pressed, illuminating the display for five seconds before switching off to conserve energy. Power draw is limited to the two AAA cells, so there is no measurable impact on household electricity consumption.
