YIER BB-02 Portable Wireless Speaker
Matters Needing Attention
To use the player correctly and ensure that it performs well, please read and observe:
- Do not hit the host severely.
- Do not touch benzene, thinners, and other chemicals. Please keep away from strong magnetic and electric fields.
- Please avoid direct light or heating appliances.
- Do not disassemble, repair, or modify by yourself.
- Please sort and properly dispose of waste packaging, batteries, and old electronics.
- Do not expose the product to rain or damp surroundings to prevent fire or electric shock.
Precautions for the Charger
- Insert one end of the power cord into the [5V] socket of the machine, and insert the other end of the USB into a matching plug or computer. The “red light” is on when charging, and it goes out when it is fully charged.
- It is recommended that the product not be played while charging, so as not to charge for a long time and shorten the battery life.
- Do not put water containers next to the charger to avoid water splashing and causing a short circuit of the charger, resulting in overheating, leakage, and malfunction.
- Do not put heavy objects on the power cord or try to modify the power cord; otherwise, it may cause electric shock or fire.
- It is forbidden to use other types of chargers, as they will affect the battery life or damage the machine.
- The machine has a built-in charging protection circuit, which can be connected to a computer or charger for a long time. About 3–4 hours to fully charge the battery; the battery’s lifetime will vary depending on the light usage time or the volume level.
- When the battery power is low, the system will automatically shut down. Please charge it at least once a month to protect the battery and prolong its life.
Speaker Connection
- Wireless speaker connection: Turn on the speaker device, turn on the wireless connection function of the mobile phone, and search for the wireless device “BB-02” (no need to enter a password, connect directly).
- TWS connection: When the new machine is dual-connected for the first time, long-press the TWS button for both machines. When you hear “TWS cleared,” it means pairing is in progress. When the pairing is successful, you will hear “TWS paired.” (Under normal circumstances, the pairing is successful within 6 seconds, but the greater the environmental interference, the longer the pairing time.)
- If the two devices have been connected, turn them off and on again. The machine will automatically interconnect; no need to reconnect.
- When TWS is disconnected or reconnected, the host needs to be operated (the host means: the one that can be controlled by Bluetooth is the host, and the one that needs to be paired is the slave).
- Other connections: The machine automatically detects and recognizes the external device when it is turned on, and enters the wireless connection AUX mode after it is turned on. When the TF card or USB is inserted, it automatically recognizes the playback. The latter has the priority principle, and the playback mode can also be switched manually. The audio signal line does not switch automatically; use the [M] key to switch to play in AUX mode.
