3. Setup

3.1 Battery Installation

Open the battery compartment cover on the back of the alarm clock.
Insert two (2) AAA Micro LR03 batteries, observing the correct polarity (+ and - markings).
Close the battery compartment cover securely.

Upon battery insertion, the alarm clock will power on and automatically begin searching for the DCF-77 radio signal.

3.2 Automatic Time Synchronization (DCF-77)

The Technoline WT 235 is a radio-controlled clock, meaning it automatically synchronizes its time with the DCF-77 signal broadcast from Mainflingen, Germany. This ensures highly accurate timekeeping.

After battery installation, the clock will automatically attempt to receive the DCF-77 signal. This process may take several minutes.
A radio signal icon will flash on the display during signal reception. Once the signal is successfully received and synchronized, the icon will appear solid.
For optimal reception, place the alarm clock away from electronic devices that may cause interference (e.g., TVs, computers, mobile phones) and near a window.

3.3 Manual Time Setting (if needed)

If the radio signal cannot be received or if you are outside the DCF-77 reception area, you can set the time manually.

Press and hold the TIME button for approximately 3 seconds to enter manual time setting mode. The hour digits will flash.
Use the '+' or '-' buttons to adjust the hour.
Press the TIME button again to confirm the hour and move to minute setting. The minute digits will flash.
Use the '+' or '-' buttons to adjust the minutes.
Press the TIME button again to confirm the minutes and exit time setting mode.

3.4 Time Zone Setting

The clock allows for a time zone offset of ±12 hours from the DCF-77 signal.

In normal time display mode, press the TIME button once. The time zone offset will be displayed (e.g., '00' for no offset).
Use the '+' or '-' buttons to adjust the time zone offset. Each press changes the offset by one hour.
Press the TIME button again to confirm the setting and return to normal display.

4. Operating Instructions

4.1 Display Modes

The clock cycles through different display modes for time, date, and temperature.

In normal display mode, the time, date, day of the week, and indoor temperature are shown simultaneously.
Press the '+' button to toggle between 12-hour and 24-hour time formats.

4.2 Setting the Alarm

Press and hold the ALARM button for approximately 3 seconds to enter alarm setting mode. The alarm hour digits will flash.
Use the '+' or '-' buttons to adjust the alarm hour.
Press the ALARM button again to confirm the hour and move to minute setting. The alarm minute digits will flash.
Use the '+' or '-' buttons to adjust the alarm minutes.
Press the ALARM button again to confirm the alarm time and exit setting mode.

4.3 Activating/Deactivating the Alarm

In normal time display mode, press the ALARM button once. The alarm icon will appear on the display, indicating the alarm is active.
Press the ALARM button again to deactivate the alarm. The alarm icon will disappear.

4.4 Snooze Function

When the alarm sounds, gently touch the top surface of the alarm clock (the touch sensor) to activate the snooze function.

The alarm will pause for approximately 5 minutes and then sound again.
You can repeat the snooze function multiple times.
To stop the alarm completely, press any button on the front of the clock (TIME, ALARM, '+', or '-').

4.5 Backlight

To temporarily illuminate the display, gently touch the top surface of the alarm clock (the touch sensor).

The backlight will activate for a few seconds, making the display visible in low light conditions.
This function is separate from the snooze function, though both are activated by the same touch sensor.

5. Maintenance

5.1 Cleaning

Clean the alarm clock with a soft, dry cloth.
Do not use abrasive cleaners, solvents, or chemical agents, as these may damage the casing or display.
Avoid getting moisture into the device.

5.2 Battery Replacement

When the display becomes dim or the functions are erratic, it is time to replace the batteries.
