To replace the battery, open the battery compartment located at the back of the unit. Remove the old battery and insert a new AAA battery, ensuring the polarity is correct. Close the compartment securely.
Check if the battery is inserted correctly and has sufficient charge. If the problem persists, try replacing the battery or resetting the device by removing and reinserting the battery.
For better FM reception, fully extend the antenna and adjust its position. Try changing your location to reduce interference from electronic devices or structures.
To preset stations, tune to the desired station, press and hold the preset button, and then select the preset number you wish to assign. Release the button to save the station.
Use a soft, dry cloth to gently wipe the exterior of the device. Avoid using solvents or abrasive materials that could damage the surface.
Use the volume control knob located on the side of the device to increase or decrease the volume to your desired level.
Check if the volume is set too high, which can cause distortion. If necessary, try repositioning the antenna or moving to a different location to improve signal clarity.
To switch between AM and FM bands, use the band selector switch located on the device. Slide it to the desired band position.
To reset all settings, remove the battery and leave it out for a few minutes before reinserting it. This will clear any customized settings.
Plug your headphones into the headphone jack located on the side of the device. Adjust the volume to a comfortable level using the volume control.
