2. The default working mode on power-up is Bluetooth mode.

7. Bluetooth Mode

1. Short-press the Bluetooth button to enter Bluetooth mode — the speaker will prompt "Bluetooth" and the indicator flashes blue.
2. Turn on Bluetooth on your phone, search for devices, and connect to "Dash 4." Once connected, the speaker prompts and the indicator turns solid blue.

4. Long-press the Bluetooth button to disconnect the current connection — the speaker prompts "Bluetooth pairing," so other devices can find and pair with it.

Note: if the speaker's Bluetooth pairing memory has been cleared, "forget"/ignore Dash 4 on your device and search again to re-pair.

8. Wireless Mic Mode

2. Long-press the microphone's Power button to turn it on — its indicator flashes white. The mic connects to the speaker automatically; once connected, the speaker prompts "ding," its indicator turns solid green, and the mic's indicator turns solid white.
3. Pairing a second microphone: short-press to pair, following the same steps as the first microphone.
4. Backing music mode: long-press to turn on/off — this removes vocals and retains accompaniment (final effect depends on the audio source).

Dash 4 supports one 2.4G wireless microphone out of the box, and the speaker itself can support up to 2 wireless microphones paired simultaneously.

Additional microphone: a separate wireless microphone can be purchased as an add-on (pricing around ₹1,000, varying by batch number). Contact Portronics support to check compatibility and pricing for your unit's batch before ordering.

9. Suppressing/Restoring Vocals in Music

Short-press the Vocal button to suppress the vocal track in a song, turning it into a backing track — the speaker prompts "voice canceling." Short-press again to restore it — the speaker prompts "voice back."

This only works when the speaker is paired with the included wireless microphone.

10. Headphone Mode

1. Power on the microphone and connect it to your device via Bluetooth.

19. Important Safety Instructions

1. Do not use the speaker in extreme cold or hot environments.
2. Avoid dropping or hitting the speaker with a hard object — this may cause hardware damage.
3. Avoid excessive, prolonged charging, as it will shorten battery lifetime; fully charge the speaker before first use.
4. If the battery is low, the indicator flashes and a voice prompt says "battery low" — charge the speaker promptly.
5. If not using the speaker for a long time, charge it at least once a month to prevent the lithium battery from degrading due to excessive discharge.
6. Adjust the volume to a reasonable level to avoid disturbing others.
