Digital alarm clock TFA Twist — rectangular grey, LCD display, battery AA 1.5V, 71×117×37 mm

TFA Twist — rectangular grey digital alarm clock with LCD display, powered by a single AA 1.5 V battery. Compact dimensions (71×117×37 mm) and a matt rubberised surface provide a comfortable hand feel and stable placement on bedside tables or desks. The display shows the current time and, when set, the alarm time next to it. The display rotates automatically when the clock is turned, enabling quick activation or deactivation of the alarm by rotating the unit 180°.

Advantages

The TFA Twist combines a simple, flat design with practical features: a polarising low-glare LCD, an inverted backlight that produces bright digits on a dark background for five minutes, and an automatic night light activated by a light sensor. Alarm activation is intuitive — rotate the clock to switch the alarm on or off — and a large sensor button on top provides snooze and instant backlight control. Radio-controlled timekeeping ensures accurate time without manual adjustment, and settings allow selection of time zone and 12/24-hour format.

How to use

Insert a fresh AA 1.5 V battery into the battery compartment and place the clock on a stable surface. The radio-controlled mechanism will set the time automatically after reception of the signal. To set or deactivate the alarm, rotate the clock 180°; the display rotates with the housing and indicates the alarm time when active. Use the large sensor button on top to trigger the snooze function or to activate the inverted backlight for five minutes. Night backlight behaviour can be switched on or off via the settings menu and will activate automatically in low ambient light if enabled.

Usage recommendations

For reliable radio reception, place the clock away from large metal objects and electronic equipment that may cause interference. Replace the AA battery once display brightness diminishes or if the clock loses time; use an alkaline battery for longer life. If using during travel, disable the automatic night light when not required to conserve battery power.
