Large Green Digits for Bedroom Use

This digital clock shows 2-inch numbers in green on a black case, making the time readable from across the room. Front-facing buttons keep every control visible without turning the unit around. It suits anyone who wants a clear, plug-in bedside clock with a simple layout.

Adjustable Brightness and Battery Backup

Five brightness levels are cycled with a single tap on the top button, so the display stays comfortable day or night. The clock runs on AC power and uses two AAA batteries (not included) to preserve the time and alarm settings during outages; the display stays dark on battery power while the alarm still sounds.

Loud Alarm Options for Heavy Sleepers

Five selectable tones include Birds Chirping, Beep, Soft Music, Ode to Joy and Siren, with four volume steps reaching 110 dB. The alarm rings for up to 15 minutes if ignored, and a 9-minute snooze gives a short extra rest. Buyers who want a silent vibrating alert or a second independent alarm time will not find those features here.

Questions about this item

What power connection does the AuroraCalm U2-1-Green use and what happens during a power cut?

It plugs into mains power for daily use; two AAA batteries (not included) keep the time and alarm settings alive and still sound the 110 dB alarm if the mains fails, though the display stays dark on battery backup.

How much space does the 5.5 in wide clock need on a bedside table?

The unit measures 5.5 in wide, 1.5 in deep and 4.0 in high, so allow at least that footprint plus a little clearance for the front-facing buttons and top brightness control.

How do I set the alarm and which step do people miss?

Press the alarm-set button, choose one of the five sounds and a volume up to 110 dB, then confirm the time; the step often missed is pressing the final confirm or "save" button so the setting actually sticks.
