Digital alarm clock TFA-Dostmann 60.4523.01 Black LCD

The TFA-Dostmann 60.4523.01 digital alarm clock is a wall- or counter-mounted timepiece designed for waiting areas, receptions, offices and public buildings. Its large black rectangular LCD shows the time in a very large format with second-accurate display and automatic summer/winter time adjustment. A distinguishing feature is the dual temperature readout: the clock displays both indoor temperature and outdoor temperature received from a small wireless transmitter with up to 100 m range. The device runs on AA batteries and supports a 433 MHz transmission frequency.

Advantages

The clock provides an extremely clear, high-contrast display that is readable from a distance and allows the user to choose whether the outdoor temperature or the time should be shown in large characters. Its compact, unobtrusive black design fits various interiors, and the automatic daylight saving time switching ensures correct time without manual adjustments. The included wireless temperature transmitter enables separate outdoor temperature monitoring up to 100 m away.

Suitable for

• Waiting rooms and reception areas
• Office walls and desks

How to use

Install AA batteries in the clock and in the outdoor transmitter according to the polarity markings. Place the small transmitter outdoors within line-of-sight or typical operating distance (up to 100 m) from the clock, avoiding metal obstructions where possible. Mount the clock on a wall or place it on a counter; the display will synchronise and show the time and indoor temperature automatically. Use the device buttons to select whether the outdoor temperature or the time is shown in the large display area and to set the alarm if needed.

Recommendations

For reliable outdoor temperature reception, position the transmitter in a sheltered but ventilated location and keep it within the specified range. Replace batteries before they are fully depleted to maintain accurate time and temperature updates. Avoid placing the clock or transmitter near large metal objects or strong radio sources that may interfere with the 433 MHz signal.
