3) Precautions
1. Before use, ensure the supply voltage matches the speaker's requirements and employ the
specified DC 12V power adapter.
2. Avoid using the speaker in high-temperature, humid, or dusty environments.
3. Do not leave the speaker near magnetic objects for extended periods to avoid compromising
sound quality and device performance.
4. When cleaning the speaker, first disconnect the power supply and gently wipe it with a soft, dry
cloth. Do not use chemical cleaners.
5. If the speaker is not used for an extended period, disconnect the power supply.
6.
When the device is playing music, do not charge external devices through its USB or
Type-C ports.
7. During operation, magnetic wireless charging generates normal temperature rise. When the
temperature reaches the preset threshold, the device automatically activates its overheating
temperature control protection and suspends charging to cool down.
8. During charging, ensure the magnetic adsorption is securely aligned to prevent misalignment
or displacement, which could reduce charging efficiency and cause localized abnormal heating.
9. The charging area must not contain metal objects, bank cards, magnetic components, or hard
debris to avoid interfering with magnetic positioning, obstructing charging, or posing
high-temperature risks.
10. When the phone/charging terminal has an excessively thick casing or its built-in magnetic
components do not meet specifications, the charging power will be reduced, potentially triggering
abnormal charging protection.
11. If Bluetooth cannot connect, check whether other devices are connected to the current system. If
so, restart the device and reconnect. The Bluetooth signal distance should be
≤
10 meters.
