- Power On/Off & Volume (VOL/POWER): Rotate the left knob to turn the system on and adjust the overall volume.
- Microphone Blend & Phase (MIC/PHASE): Rotate the right knob to blend the internal microphone signal with the piezo pickup. Press the knob to toggle the phase.
- Effects Control (DELAY/REVERB/CHORUS): The center knob controls the built-in effects. Rotate to select and adjust the intensity of Delay, Reverb (Metal/Hall), and Chorus.
- Electro-Acoustic Mode: To use the system as an electro-acoustic pickup, connect a standard instrument cable from the output jack to an amplifier or PA system.
Battery Charging
The Skysonic R3 uses a dedicated 3.7V rechargeable battery. When the battery level is low, the system's performance may degrade, or it may cease to function.
- Remove Battery: Carefully open the battery compartment on the integrated output terminal and remove the rechargeable battery.
- Connect to Charger: Insert the battery into the provided battery charger.
- Charge: Plug the charger into a suitable power source. The charger will indicate when the battery is fully charged (refer to charger instructions for specific indicators).
- Reinstall Battery: Once fully charged, remove the battery from the charger and reinsert it into the battery compartment, ensuring correct polarity.
Note: The provided charger is specifically designed for this battery. Do not use other chargers unless explicitly stated as compatible.
Maintenance
- Cleaning: Wipe the control panel and output jack with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Battery Care: For optimal battery life, avoid fully discharging the battery frequently. If storing the system for an extended period, ensure the battery is partially charged (around 50%) and remove it from the unit.
- Connections: Periodically check all internal and external connections to ensure they are secure.
