- Auxiliary Cable Operation: Music can be played by connecting an Aux-in audio cable from a device to the Nomad Alpha.
- Bluetooth Pairing:
- Switch on the main power switch.
- Press the power button for approximately three seconds; the LED will flash blue/red.
- Enable Bluetooth on your mobile device.
- Select 'Nomad Alpha' from the list of available devices.
- A "Bluetooth connected" audio prompt confirms successful pairing.
- If the LED is not flashing, hold the UNISYNC button for 5 seconds to initiate pairing.
- The speaker stores the last paired device and will automatically search and pair if within range.
- Controls:
- Play/Pause/Answer: A dedicated button for playing/pausing music and answering calls.
- Volume Control: Short presses of '-' decrease volume, and '+' increase volume.

- Main Power Switch: Located on the side panel, this switch must be in the 'ON' position for the Nomad Alpha to be operational and for the power standby function to work.
Maintenance Features
Proper care and maintenance are essential for the longevity and performance of the Nomad Alpha:
- Waterproofing and Dustproofing: The IP67 rating ensures the speaker can withstand submersion up to 1 metre for 30 minutes and is dustproof. However, it is not intended for constant underwater use.
- Side Panel Cap: Always ensure the side panel cap is clean, free of debris, and properly fitted and locked before use to maintain its waterproof and dustproof integrity. Water ingress due to an improperly closed cap will void the warranty.
- USB Cables: The included USB cables are NOT waterproof and should not be exposed to water.
- Post-Submersion Care: If audio is muffled after submersion, gently shake the Nomad Alpha to clear excess water.
- Saltwater Exposure: If exposed to saltwater, thoroughly clean the speaker with fresh water immediately after use. Avoid applying excessive force to any surfaces when the device is wet.
- Rubber Seal Inspection: Periodically check the rubber seal for wear and tear. Clean the Nomad Alpha with a soft, moist cloth, ensuring no dirt, hair, or sand is on the rubber seal ring.
- Cleaning Agents: Do not use oily solvents or chemicals for cleaning, as these can damage the device.
Adhering to safety guidelines is crucial for preventing damage to the device and ensuring user safety:
- Charging When Wet: Never attempt to charge the Nomad Alpha if it is wet or if water is suspected to have seeped in. Thoroughly dry the device and all connections before opening the side panel cap and connecting to a power source. Failure to do so can result in electrical shock, fire, or damage, voiding the warranty.
- Charging and Use: Do not use the Nomad Alpha while it is charging.
- Heat Sources: Keep the Nomad Alpha away from open flames, heat sources, or excessive heat.
- Modification/Repair: Do not open, modify, repair, or remove any original components. Repair work must be carried out by a qualified technician. Removing the built-in battery or grill cover can damage the device and compromise its water resistance.
- Sound Levels: Ensure sound levels are appropriate for your environment and comply with local regulations. Be aware of your surroundings and potential hazards while enjoying your Nomad Alpha.
