Operation
1. Adjusting the Head Strap

2. Using the Magnetic Battery Packs
The T3 Plus includes two 8000mAh hot-swap battery packs. To attach a battery, simply align it with the magnetic connection points on the back of the head strap. It will snap into place. When one battery is depleted, you can easily swap it with a fully charged one from the charging dock without interrupting your VR experience. This provides over 4 extra hours of gameplay per battery.

3. Lightweight Mode
For a lighter experience, the battery packs can be detached. The head strap can be used independently without the added weight of the batteries. This is ideal for shorter sessions or when maximum mobility is desired.

4. Charging Mode (while in use)
When a battery pack is attached to the head strap and the headset is in use, the battery pack will automatically begin charging the Meta Quest 3/3S. This ensures your headset remains powered for extended periods.

Maintenance

To clean the head strap and battery packs, use a soft, dry cloth. For stubborn dirt, a slightly damp cloth with mild soap can be used, ensuring no moisture enters the electronic components. Do not use abrasive cleaners or solvents.

Store the head strap and battery packs in a cool, dry place away from direct sunlight and extreme temperatures. Ensure battery packs are partially charged (around 50%) before long-term storage to preserve battery health.
