Maintenance

• Keep the radio dry and clean. Wipe with a soft, dry cloth.
• Avoid exposing the device to extreme temperatures, direct sunlight, or high humidity.
• Do not attempt to disassemble or repair the radio yourself, as this will void the warranty.
• When not in use for extended periods, store the radio in the provided storage bag.

Troubleshooting

• Poor Radio Reception: Extend the telescopic antenna fully. Try repositioning the radio or connecting the external antenna. Interference from other electronic devices can also affect reception.
• Charging Issues: Ensure you are using a standard 5V/2.1A USB power adapter or a computer's USB port. High-power PD chargers may not be compatible. Check the USB-C cable for damage.
• No Sound/Low Volume: Check the volume level. Ensure the correct mode (Radio, Bluetooth, MicroSD) is selected. If using earphones, ensure they are properly plugged in.
• Bluetooth Pairing Failure: Ensure the radio is in Bluetooth mode and discoverable. Turn off and on Bluetooth on both devices. Make sure no other devices are connected to the radio.
• MicroSD Card Not Recognized: Ensure the MicroSD card is inserted correctly. Check if the card is formatted to a compatible file system (e.g., FAT32) and contains supported audio formats (MP3, WAV, WMA, APE, FLAC).
• Fragile Antenna: Handle the telescopic antenna with care, especially the thinnest section, to prevent bending or breaking.
• Mono Audio on Radio: The radio's output for broadcast reception is mono. If using stereo headphones, you may only hear sound from one earbud for radio broadcasts.
• Accidental SOS Alarm Activation: The SOS alarm is very loud. Be careful when pressing the flashlight button, as a long press activates the alarm.
