Important: If the LED indicator doesn`t light up red while charging, follow the troubleshooting steps below:
1) Clean the charger cord "head" and the charging port on the speaker with a small soft brush to remove debris.
2) Try to charge the speaker for at least 3 hours with another charging cable/another power source/another adaptor (if available).
3) Try to turn ON your HD7 by pressing and holding the POWER button for 3 seconds.
4) Check if the speaker works via LINE-IN mode.
If the issue was resolved with another charging cable, please check another section "Defective charging cable".
Note 1: High humidity and extreme temperatures can cause the deformation of the device and affect its battery performance.
Note 2: If your speaker is more than 1 year old, its battery life may be reduced due to the natural lifecycle of the Li-ion battery.
