Caution: Do not do any operation during the upgrade progress!!! Or the radio will be damaged! 5.Telescopic antenna assist Middle Wave An auxiliary middle wave receiving circuit is integrated in the radio, you can try to use the telescopic antenna to increase the MW signal strength and to improve the performance of SNR ,especially effective outdoor. 6.About MW(medium-wave): 1.This radio is equipped with a built-in ferrite bar MW antenna, and also has a telescopic antenna to assist in MW reception. When receiving medium waves, you can try to extend the telescopic antenna to improve the reception capability. 2.This radio can be connected to an external antenna. You can use a 3.5mm headphone jack and a longer wire to modify it into an external antenna, which helps in receiving medium and short waves and FM. It is important to note that any pin of the 3.5mm jack can serve as a signal pin, allowing you to design your own external antenna. However, it does not support connecting to active MW antennas. Q: Why is the medium-wave reception performance relatively weak? A:Due to the interference of LCD, the medium wave reception performance of this radio is indeed a bit weak. You can pull out the telescopic antenna to enhance the reception performance of MW (we have designed a circuit to enhance the reception of MW with telescopic antenna), or try it outdoors to see if the medium wave reception of this radio is really defective. Indoors, we still recommend connecting to Wi-Fi to listen to online radios. 7.How to adjust the meter band and bandwidth: 1.The first knob of the radio is used to adjust the meter band. In the SW playback interface, simply press the middle position of the first knob once. When you see the meter band value blinking, you can adjust the meter band by turning the knob. 2.The second knob of the radio is used to adjust the bandwidth. In the SW/MW playback interface, simply press the middle position of the second knob once. When you see the bandwidth value blinking, you can adjust the bandwidth by turning the knob.

The battery voltage of the radio you received is relatively low. I suggest you charge it for a while before using it. Due to the actual capacity of the battery being about 5400mAh, it will require a longer charging time.
