44 -
45 -* Conduct compass measurements away from the node and metallic structures, adjusting for inclination angle.
46 -* Take multiple photographs from various angles to document the site setup thoroughly.
47 -* Include a detailed site description in your notes, specifying distances and orientations from nearby landmarks (e.g. Richards garden, Te Mini steam field eastern side)

49 -=== **3- GPS Considerations** ===
50 -
51 -(% class="wikigeneratedid" %)
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.

64 -
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.
