Alarm clock TechnoLine WT 590 — radio-controlled projection, silver, AAA battery

TechnoLine WT 590 is a compact radio-controlled alarm clock designed for precise timekeeping and convenient bedside visibility. Housed in a silver casing measuring 123 x 42 x 91 mm, the unit receives atomic time signals (DCF77) with the option for manual time setting. The display shows 24-hour time, calendar (month, date, weekday) and indoor temperature in Celsius, and the built-in projector casts the time onto ceilings or walls for easy reading at night. The device is powered by AAA batteries and features an LED backlight, alarm with snooze and selectable time zone setting—making it suitable for home or travel use where accurate, readable time is required.

Advantages

The radio-controlled reception ensures consistently accurate time without frequent manual adjustment, while the manual setting option provides flexibility when needed. Projection of the time onto a ceiling or wall offers quick visibility in the dark without having to look directly at the device. The compact silver housing is lightweight and portable for travel, and the long battery life (when using recommended AAA cells) reduces maintenance. Additional functions such as indoor temperature readout, calendar display and LED backlight increase everyday usability.

Suitable for

• Bedroom bedside clock with projection for night-time readability

How to use

Set the alarm time and enable Snooze as required. To project the time, aim the clock toward a flat surface such as a ceiling or wall and activate the projector; adjust the housing angle until the projected time is clear and correctly oriented. Use the LED backlight for brief illumination of the display when needed.

For reliable atomic reception, position the clock away from large metal objects and electronic devices that may cause interference. Replace batteries before significant depletion to maintain projection brightness and continuous time synchronization. Clean the projection lens gently with a soft, dry cloth to keep the projected image sharp. If traveling across multiple time zones, switch to manual mode or adjust the time zone setting to maintain correct local time.
