You’ll want to take special care with your battery pack. It powers your headgear’s network connection, sensors, and reporting channels, and maintains appropriate electrode tension against your vertebra and soft palate.
Your spare battery should remain in the charging cradle at all times; be sure to carry it and its AC adapter with you when you leave the house. Once your battery discharges fully or is removed, mechanical backups will activate progressively stronger measures until it is changed. This will also happen if any part of your headgear is exposed to water, so be very careful in the shower.
Your headgear also features a Webcam, which may be accessed by anyone who holds one of the remote controls. You’ll hear an alarm tone if the camera is blocked or otherwise disabled; as above, progressively stronger measures will be applied until the camera is seeing clearly again.
