52 +The GPS antenna is at the top and center of the unit, and will (usually) only receive signal with a clear sky view directly above. The signal is able to penetrate plastic and terracotta planters and a thin layer of soil, but may struggle if the soil layer is too thick. The BD3C will not start recording without first attaining a GPS lock.

65 +* **Charging Duration**: Both types of nodes take approximately 6-8 hours to fully charge from a flat state.
66 +* **Pre-Deployment Charging**:
67 +** Although the nodes hold their charge well, it's beneficial to give them a "top up" charge right before deployment.
68 +
69 +* **Operational Duration**:
70 +** When recording at 250 Hz, with GPS on and Bluetooth disabled, the instruments are expected to last about 30 days per charge cycle.
71 +
72 +* **Post-Retrieval Charging**:
73 +** Do not store the instruments with completely drained batteries.
74 +** After retrieval, charge the instruments to about 50-60% (indicated as "orange" level) for optimal battery health.
75 +
76 +* **Storage and Shipping Charge Level**:
77 +** Maintain a battery charge level of around 50-60% for both storage and shipping purposes.
78 +** This charge level is recommended to prevent battery damage and is safe for transportation.

101 +
102 +* **Environmental Responsibility**: Ensure that the node placement and the materials used are environmentally responsible and adhere to local regulations.
