1. Quick Reference Table

2. Speaker Won't Turn On

1. Long-press the Power button — check for the battery indicator lighting up.
2. Connect the included cable to the Type-C Charging Port and charge for at least 30–60 minutes.
3. While charging, the battery indicators should light up one at a time; if there's no indicator activity at all, try a different cable or a 5V/2A adaptor.
4. If it still won't turn on after charging, this may point to a hardware fault — contact support.

3. Won't Pair Over Bluetooth

1. Short-press the Bluetooth button to enter Bluetooth mode — the speaker prompts "Bluetooth" and the indicator flashes blue.
2. On your phone, search for Bluetooth devices and select "Dash 4."
3. If it doesn't appear or won't reconnect, the pairing memory may have been cleared (short-press the Bluetooth button twice to do this deliberately) — in that case, ignore/forget "Dash 4" on your phone and search again to re-pair from scratch.
4. To disconnect a current connection and let another device pair, long-press the Bluetooth button.

4. Wireless Microphone Won't Connect

1. Short-press the Bluetooth button on the speaker to enter Wireless Mic mode — its indicator flashes green.
2. Long-press the microphone's Power button — its indicator should flash white, then turn solid white once connected, alongside the speaker's indicator turning solid green and a "ding" prompt.
3. If it doesn't connect, power-cycle the microphone and repeat the steps.
4. Make sure the Mic Connect function hasn't been switched off — short-press the Mic Connect button on the speaker to toggle it back on if needed.

5. Pairing a Second (or Add-On) Microphone

1. Follow the same pairing steps as the first microphone — short-press to pair the second unit.
2. Dash 4 supports up to 2 wireless microphones connected simultaneously.
3. If you've purchased a separate/additional wireless microphone as an add-on (pricing is around ₹1,000, depending on batch number), check with Portronics support first to confirm it's compatible with your specific unit's batch before attempting to pair it.
4. If a compatible add-on mic still won't pair, power-cycle both the speaker and the microphone, then repeat the pairing steps from scratch.

6. Speaker Powers Off Unexpectedly

This is the intelligent power-saving function, not a fault:

• In Bluetooth mode, the speaker auto-powers off after 10 minutes of waiting to pair.
• In USB, FM, or AUX In mode, it auto-powers off after 10 minutes of playback being paused.

Long-press the Power button to turn it back on.

7. FM Radio Issues

1. Short-press the Mode button until the speaker prompts "FM mode."
2. Long-press the Next Track button to scan and automatically save available channels.
3. Use the previous/next track buttons to switch between saved channels.
4. For better reception, turn off the speaker's lights by long-pressing the Light button — the manual notes this can improve FM reception.

8. USB / AUX Playback Issues

USB:

1. Confirm the flash drive is 32GB or smaller and contains MP3, WAV, WMA, APE, or FLAC files.
2. Short-press the Mode button to select USB mode — the speaker should prompt "USB Mode."

AUX:

1. Connect a 3.5mm cable between your audio source and the AUX-In port.
2. Short-press the Mode button to select AUX In mode — the speaker should prompt "Auxiliary in."
3. Check the volume on the source device, since AUX is a passive connection.

9. Vocal Suppression / Backing Track Mode Not Working

This feature (suppressing or restoring vocals in a song) only works while the speaker is actively paired with the included wireless microphone — it won't do anything in plain Bluetooth playback without the mic connected. Pair the microphone first, then short-press the Vocal button.

10. Headphone Mode Issues

1. Power on the microphone and connect it to your device via Bluetooth first.
2. Insert 3.5mm headphones into the Headphone Port.
3. Remember that in this mode, audio plays through the headphones instead of the speaker — this is expected, not a fault.

11. Charging & Battery Issues

• Charge using a good-quality 5V/2A adaptor — an underpowered adaptor can charge slowly or not at all.
• Charge the speaker to full capacity before first use, and avoid excessive prolonged charging, which can shorten battery lifetime.
• If unused for a long period, charge the speaker at least once a month to prevent the lithium battery from degrading.
• When the battery is low, the indicator flashes and a voice prompt says "battery low" — this is your cue to charge soon, not a fault.

12. General Safety Reminders

• Do not use the speaker in extreme cold or hot environments.
• Avoid dropping or hitting the speaker.
• Keep the volume at a reasonable level to avoid disturbing others.
