- An external FM & SW antenna can be connected to the dedicated jack on the side for improved reception.
- Charging:
- Connect the USBMicroTypeC charging cable to the DC-IN 5V port on the side of the radio and to a USB power adapter (purchased separately) or a computer USB port.
- The radio can be operated while charging.
6. Operating Instructions
- Band Selection:
- Press the "FM/ST", "MW/LW", or "SW" buttons to switch between frequency bands.
- "FM/ST" cycles through FM stereo and mono modes.
- Tuning:
- Manual Tuning: Use the "TUNING" rotary knob on the top right side to adjust the frequency.
- Step Tuning: Use the "STEP" button to change the tuning step size.
- Direct Frequency Entry: Use the numerical keypad (0-9) to enter a desired frequency directly, then press "FM SET" or "MW/LW" or "SW" to confirm.
- ETM (Easy Tuning Mode): Press the "ETM" button to automatically scan and store stations into a temporary memory. This is useful for quickly finding active stations in a new location.
- ATS (Auto Tuning Storage): Press and hold the "ATS" button to automatically scan and store stations into permanent memory.
- Memory Functions:
- Store Station: Tune to a desired station, then press and hold the "MEMORY" button (M) until the display indicates storage. Use the numerical keys or tuning knob to select a memory address.
- Recall Station: Press the "MEMORY" button (M) briefly, then use the numerical keys or tuning knob to select a stored station.
- Favorite Stations: Use the "FAVOURITE" button to access frequently listened-to stations.
- Volume Control:
- Adjust the "VOLUME" rotary knob on the top left side to increase or decrease the sound level.
- Display:
- The LCD display shows the current frequency, time, signal strength, and other relevant information.
- The "DISPLAY" button may cycle through different display modes (e.g., time, signal-to-noise ratio).
- Timer Function:
- The "TIMER A" and "TIMER B" buttons are likely for setting alarm or sleep timer functions. Refer to the detailed Chinese manual for specific instructions or experiment with short presses/long presses.

8. Maintenance
- Cleaning: Wipe the radio with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Battery Care: If the radio will not be used for an extended period, remove the BL-5C battery to prevent leakage. Recharge the battery periodically to maintain its lifespan.
- Storage: Store the radio in a cool, dry place, away from dust and extreme temperatures.
9. Troubleshooting
- No Power:
- Check if the BL-5C battery is correctly installed and charged.
- Ensure the "POWER" button is pressed.
- Poor Reception:
- FM/SW: Extend the telescopic antenna fully. Try repositioning the radio or connecting an external antenna.
- MW/LW: Rotate the radio to find the best signal, as the internal ferrite bar antenna is directional.
- Check for local interference from electronic devices.
- No Sound:
- Adjust the "VOLUME" knob.
- If headphones are connected, ensure they are fully plugged in and functional.
- Display Not Working:
- Check battery level.
- Try turning the radio off and on again.
10. User Tips
- Charging: The radio does not come with a dedicated power adapter; you will need to use your own USB DC 5V adapter (at least 500mA) or a computer's USB port with the provided USBMicroTypeC cable.
- Manual Language: The included physical manual is in Chinese. This document provides English instructions.
- Battery Life: While specific battery life isn't provided, using a fully charged BL-5C battery is essential for optimal performance. Consider carrying a spare or a power bank for extended use.
- Reception: For optimal Shortwave and FM reception, ensure the telescopic antenna is fully extended. For Medium Wave and Long Wave, rotating the radio can significantly improve signal strength due to the directional nature of its internal antenna.
