3. Setup and Assembly

This kit requires soldering for assembly. Basic soldering tools (soldering iron, solder, desoldering wick/pump, safety glasses) are necessary and not included.

3.1 Assembly Steps

1. Component Identification: Before starting, identify all components using the provided component list and circuit diagram.
2. Solder Smallest Components First: Begin by soldering smaller components like resistors and diodes, followed by capacitors, IC sockets, and then larger components such as buttons, LED displays, and the rotary encoder.
3. Observe Polarity: Pay close attention to the polarity of components like diodes, LEDs, and integrated circuits. Incorrect orientation can damage components or prevent the device from functioning.
4. Solder Joints: Ensure all solder joints are clean, shiny, and form a good connection without bridging adjacent pads.
5. Install ICs: Once all soldering is complete, carefully insert the integrated circuits into their respective sockets, ensuring correct orientation.
6. Assemble Casing: Mount the assembled PCB into the acrylic casing using the provided screws and standoffs.

4.1 Control Buttons and Knob

• SW1-SW5 Buttons: Used to switch between the six main display modes (Time, Date, Weekday, Alarm, Timer, Brightness Control).
• Rotary Knob: Used for setting time/wake-up time, starting/pausing timers, and adjusting LED brightness/flashing speed.

4.2 Display Modes

The device supports six distinct display modes, accessible via the SW buttons.

• Time Display: Shows current hours, minutes, and seconds.
• Date Display: Shows current year, month, and day.
• Weekday Display: Shows the current day of the week.
• Alarm Mode: Allows setting and activating the alarm. When the alarm triggers, the 7-color LEDs will light up and flash, accompanied by an audible alert.
• Timer Mode: Offers both count-up (stopwatch) and countdown functionalities. Preset countdown options include 5, 15, 30, and 60 minutes.
• Brightness Controller: Adjusts the brightness and flashing speed of the 7-color LEDs.

4.3 Setting Time and Date

Specific instructions for setting time and date are typically provided in the detailed product manual. Generally, this involves entering a setting mode using one of the SW buttons and then using the rotary knob to adjust values.

4.4 Using Timer Functions

Navigate to the Timer Mode using the appropriate SW button.

• Countdown: Select a preset countdown (5, 15, 30, or 60 minutes) or set a custom time using the rotary knob. Press the knob to start/pause.
• Count-up (Stopwatch): In this mode, the display will count upwards. Press the knob to start/pause.

5. Maintenance

To ensure the longevity and proper functioning of your PEMENOL GY21863 Digital Alarm Clock, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the exterior of the device. Avoid using abrasive cleaners or solvents, which can damage the acrylic casing or electronic components.
• Power Source: Always use a stable 5V USB power source. Avoid connecting to power sources with incorrect voltage or current.
• Environment: Keep the device in a dry environment, away from direct sunlight, extreme temperatures, and high humidity.
• Handling: Handle the device with care to prevent physical damage to the circuit board or components.

6. Troubleshooting

If you encounter issues with your PEMENOL GY21863 Digital Alarm Clock, consider the following troubleshooting steps:

• Device Not Powering On:
  • Ensure the USB power cable is securely connected to both the device and a functional 5V USB power source.
  • Verify the ON/OFF switch is in the 'ON' position.
  • Check all soldered connections for cold joints or bridges if the device was recently assembled.
• Incorrect Display:
  • If the display shows incorrect characters or segments are missing, check the soldering of the LED display modules and the integrated circuits.
  • Ensure ICs are correctly seated in their sockets and oriented properly.
• Buttons/Knob Unresponsive:
  • Check the soldering of the buttons and rotary encoder.
  • Ensure no debris is obstructing the button mechanisms.
• Alarm Not Sounding/LEDs Not Flashing:
  • Verify the alarm settings are correctly configured and activated.
  • Check the soldering of the buzzer and the 7-color LEDs.
