Introducció
The Dykbcells Four-Band Radio Signal Generator is a professional device designed for radio enthusiasts, technicians, and educators. It covers Long Wave (LW), Amplitude Modulation (AM), Short Wave (SW), and Frequency Modulation (FM) broadcast bands. Featuring precise Digital PLL (Phase-Locked Loop) frequency synthesis, multiple internal modulation tones, and dual input options (Bluetooth and external audio), this generator is ideal for radio repair, alignment, educational demonstrations, and signal analysis.
Critical Warning: Use only standard 5V chargers. Fast chargers will damage the unit.

Consells per a l'usuari
- For optimal Bluetooth audio quality and to minimize interference, ensure your connected audio device's volume is set high, but not at its absolute maximum. Adjusting it one or two steps below maximum often yields the best results.
- When using the signal generator for radio alignment, ensure proper shielding and grounding to prevent external interference from affecting your measurements.
- Always double-check battery polarity before inserting the 18650 battery to prevent damage to the unit.
Resolució de problemes
- Sense alimentació / La unitat no s'encén:
- Ensure the 18650 battery is correctly installed with the right polarity and is sufficiently charged. If using a new battery, charge it fully before first use. Check the DC charging port and cable for damage.
- No Signal Output:
- Verify that the frequency is set correctly and within the supported bands. Check all cable connections, including the antenna interface. Ensure the receiving radio is tuned to the correct frequency and band.
- Poor Audio Quality / Noise on Bluetooth:
- Adjust the volume on your connected Bluetooth device as per the "Bluetooth Audio Optimization" tip in the Operation Guide. Ensure the Bluetooth connection is stable and there are no other interfering devices nearby.
- Frequency Adjustment Not Responding:
- Short press the encoder switch to ensure a digit position is selected for adjustment. If the issue persists, try powering the unit off and on again.
Manteniment
- Neteja: Feu servir un drap suau i sec per netejar l'exterior de la unitat. Eviteu utilitzar productes químics agressius o materials abrasius.
- Emmagatzematge: Store the signal generator in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the 18650 battery.
- Cura de la bateria: Always use a standard 5V charger. Avoid overcharging or completely draining the battery. Replace the battery if you notice a significant decrease in performance or capacity.
- Eviteu les gotes: Protect the unit from physical shocks and drops, which can damage internal components or the OLED display.
