To power on the speaker, press and hold the power button for a few seconds until you hear an audible prompt or see an indicator light. To power off, repeat the process.
Operating Instructions
1. Bluetooth Pairing
- Ensure the speaker is powered on and in Bluetooth pairing mode. It will usually emit a sound or have a blinking LED indicator.
- On your device (smartphone, tablet, computer), enable Bluetooth and search for available devices.
- Select "JINSERTA Speaker" or a similar name from the list of found devices.
- Once connected, the speaker will provide an audible confirmation, and the LED indicator will typically become solid.

- Ensure both speakers are powered off.

- On one of the speakers, double-press the power button (or designated TWS button, if available) to initiate TWS pairing. The speakers will search for each other.
- Once successfully paired, you will hear a confirmation sound, and one speaker will act as the master (left channel) and the other as the slave (right channel).
- Now, connect your device to the master speaker via Bluetooth as described in the "Bluetooth Pairing" section.
3. TF Card Playback
The speaker supports TF card playback for MP3 format audio files (up to 32GB, card not included).
- Insert a TF card with MP3 music files into the designated TF card slot on the speaker.
- The speaker should automatically switch to TF card playback mode. If not, press the mode button (if available) to switch.
- Use the speaker's controls to play, pause, skip tracks, and adjust volume.
4. Hands-Free Calling
When connected to your smartphone via Bluetooth, the speaker's built-in microphone allows for hands-free calls.
- To answer an incoming call, press the multi-function button (usually the play/pause button).
- To end a call, press the multi-function button again.
- To reject an incoming call, press and hold the multi-function button.
Maintenance
Cleaning
Wipe the speaker with a soft, dry cloth. Do not use abrasive cleaners or solvents. For stubborn dirt, a slightly damp cloth can be used, ensuring no liquid enters the ports.
Water Resistance (IP65)
The speaker has an IP65 rating, meaning it is protected against dust ingress and low-pressure water jets from any direction. It is not designed for submersion. Ensure all port covers are securely closed before exposure to water.

No Sound
Check the volume levels on both the speaker and your connected device. Ensure the speaker is properly paired via Bluetooth or that the TF card is correctly inserted and functioning.
Bluetooth Pairing Issues
Make sure the speaker is within the effective range (up to 10 meters) of your device. Turn off and on both the speaker and your device's Bluetooth. Forget the speaker from your device's Bluetooth list and attempt to pair again.
Short Battery Life
Battery life can vary based on volume level and usage. Ensure the speaker is fully charged before use. If battery life significantly degrades, contact support.
