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.

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.

72 -* **Post-Retrieval Charging**:
73 -** Do not store the instruments with completely drained batteries.

76 -* **Storage and Shipping Charge Level**:
