3. Setup and Installation

3.1 Battery Installation

1. Remove the battery compartment cover on the back of the clock.
2. Insert one (1) AA 1.5V battery, ensuring the correct polarity (+/-).
3. Replace the battery compartment cover.

3.2 Initial Time Synchronization (DCF77)

After inserting the battery, the clock will automatically attempt to receive the DCF77 radio signal. The hands will move to the 12 o'clock position and then begin searching for the signal. This process can take several minutes, or up to 24 hours in areas with weak reception.

• Place the clock near a window or in an open area for best reception.
• Avoid placing it near electronic devices that may cause interference (e.g., TVs, computers, microwaves).
• Once the signal is received, the clock will automatically set itself to the correct time.

To manually initiate a signal search, press the 'REC' (Forced Reception) button on the back of the clock (see Figure 2.2).

3.3 Mounting the Clock

The clock features a central universal hanging system for easy installation.

1. Choose a suitable location on a wall, ensuring it is sturdy enough to support the clock's weight (approx. 1.07 kg).
2. Install a screw or hook into the wall at the desired height.
3. Hang the clock securely using the hanging slot on the back.

4. Operation

4.1 Automatic Time Adjustment

The Perel Radio-Controlled Wall Clock automatically adjusts its time based on the DCF77 signal. This includes automatic switching between summer and winter time (Daylight Saving Time and Standard Time).

Figure 4.1: The clock automatically adjusts for summer and winter time changes via the DCF77 radio signal.

4.2 Reading the Display

• Time: Read the time using the large hour, minute, and second hands on the main dial.
• Temperature: The left small dial indicates the ambient temperature in degrees Celsius.
• Humidity: The right small dial indicates the relative air humidity in percentage (%).

4.3 Manual Time Setting (If Needed)

In rare cases where the DCF77 signal cannot be received (e.g., outside the reception range), you can manually set the time:

1. Press and hold the 'SET' (Manual Setting) button on the back of the clock (see Figure 2.2).
2. The hands will start to move. Release the button when the hands reach the desired time.
3. Note: Manual setting will be overridden once the DCF77 signal is successfully received.

5. Maintenance

5.1 Cleaning

• Wipe the clock's surface with a soft, dry cloth.
• Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the finish.

5.2 Battery Replacement

When the clock hands stop moving or the time becomes inaccurate, it is likely time to replace the battery.

1. Remove the old battery from the compartment.
2. Insert a new AA 1.5V alkaline battery, observing polarity.
3. The clock will automatically attempt to re-synchronize with the DCF77 signal after battery replacement.
