Setup
1. Power Connection
- Unpack the alarm clock and its power adapter.
- Insert the small end of the power adapter into the DC IN port located on the back of the alarm clock.
- Plug the other end of the power adapter into a standard electrical outlet. The display will illuminate.
2. Initial Setup and Radio Control Time Synchronization
Upon initial power-up, the clock will attempt to synchronize with the radio-controlled time signal (DCF77). This process may take several minutes. Ensure the clock is placed away from electronic interference for best reception.
- A radio signal icon will flash on the display during synchronization.
- Once synchronized, the icon will become solid, and the time, date, and day of the week will be automatically set.
- If synchronization fails, you may need to manually set the time (see "Operating" section).
Operating Instructions
1. Display Brightness Adjustment
The display features adjustable brightness. Press the LIGHT/SNOOZE button (usually located on top) to cycle through different brightness levels or to turn off the display backlight for undisturbed sleep.
2. Setting the Alarm
- Press the ALARM button to enter alarm setting mode.
- Use the +/- buttons to adjust the hour, then press ALARM again to confirm.

4. Projection Feature
The WT 537 can project the time and indoor temperature onto a wall or ceiling. The projection lens is located on the side of the unit.
- To activate/deactivate the projection, press the PROJECTION button.
