Setup Guide
1. Charging the Speaker
- Locate the USB Type-C charging port, usually protected by a rubber flap on the side of the speaker.
- Open the rubber flap and connect the provided USB Type-C cable to the speaker.
- Connect the other end of the USB cable to a standard USB power adapter (5V/1A recommended, not included) or a computer's USB port.
- The digital display will indicate charging status. A full charge typically takes approximately 2-3 hours.
- Once fully charged, disconnect the cable and ensure the rubber flap is securely closed to maintain IPX7 waterproofing.
2. Powering On/Off
- To Power On: Press and hold the Power / Play / Pause button for 3-5 seconds until the display lights up and you hear an audible prompt.
- To Power Off: Press and hold the Power / Play / Pause button for 3-5 seconds until the display turns off and you hear an audible prompt.
3. Bluetooth Pairing
- Ensure the speaker is powered on and in Bluetooth pairing mode. The Bluetooth icon on the display will typically flash, indicating it's ready to pair.
- On your smartphone, tablet, or other Bluetooth-enabled device, go to the Bluetooth settings.
- Search for available devices. You should see "Q90" or "PRSCFUM Q90" in the list.
- Select "Q90" to connect. Once connected, the Bluetooth icon on the speaker's display will stop flashing and remain solid, and you will hear a confirmation sound.
- The speaker will automatically attempt to reconnect to the last paired device when powered on.
4. Setting the Time
The speaker features a digital time display. Specific instructions for setting the time are usually found in the included user guide. Generally, this involves a combination of pressing the 'M' (Mode) button and volume buttons. Refer to the physical user guide for precise steps.

Stereo Pairing (TWS Function)
If you have two PRSCFUM Q90 speakers, you can pair them together for a true wireless stereo (TWS) experience. Specific instructions for TWS pairing are typically:
- Ensure both speakers are powered on and not connected to any other Bluetooth device.
- On one speaker (this will be the primary speaker), double-press the Power / Play / Pause button (or a dedicated TWS button if present, refer to your physical manual).
- The speakers will search for each other and automatically pair. A confirmation sound will indicate successful TWS connection.
- Once paired, connect your device to the primary speaker via Bluetooth as described in the "Bluetooth Pairing" section. Audio will now play through both speakers in stereo.

- Cleaning: Wipe the speaker with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Waterproofing: Always ensure the rubber flap covering the charging port is securely closed when using the speaker near water to maintain its IPX7 waterproof rating.
- Storage: Store the speaker in a cool, dry place away from direct sunlight and extreme temperatures.
