^{* Measurement accuracy depends on various factors. This value is obtained under normal conditions with an unobstructed view, good satellite distribution, low ionospheric activity, and no electromagnetic interference or multipath effects.

** Base station calibration coordinate accuracy depends on various factors. For surveying, high-precision flight paths, etc., it is recommended to calibrate during periods of low ionospheric activity, in open, unobstructed environments with no electromagnetic interference or multipath effects, using a Network RTK mountpoint supporting four or more satellite systems.}

Actual power draw may be higher when accounting for losses in the power supply. ** Low-power mode is not recommended for use at temperatures of -40° to -20° C (-40° to -4° F).}
Supported Power Supply	1. DJI Dock 3 PoE Output Port 2. Third-party PoE Power Supplies: IEEE 802.3bt Type 4 (PoE++): 52 V to 57 V output, max 99.9 W per port; operating range -40° to 55° C (-40° to 131° F) IEEE 802.3bt Type 3 (PoE++): 50 V to 57 V output, max 60 W per port; operating range -30° to 55° C (-22° to 131° F) IEEE 802.3at Type 2 (PoE+): 50 V to 57 V output, max 30 W per port; operating range -20° to 55° C (-4° to 131° F) ^{Non-standard PoE or Type 1 power supplies are not supported; the device will show a solid red indicator light if an unsupported supply is connected. Type 2 supports Gateway Mode only.}
Backup Battery	LiPo Capacity: 3250 mAh Energy: 23.4 Wh
Backup Battery Operating Time (at room temperature)	Battery preservation mode is enabled by default when powered via PoE. In the event of a sudden power loss, estimated runtime is: Gateway Mode: approx. 45 min Relay Mode: approx. 30 min ^{Battery preservation mode: when powered via PoE, the system keeps battery voltage between 7.0 V and 7.4 V. If the battery voltage at insertion exceeds 7.5 V, the system will discharge it to the safe threshold before entering preservation mode; the battery will not charge to full capacity. Battery discharge performance may decrease in low temperatures, reducing actual operating time.}
Backup Battery Charging	Supports 9V or 12V PD charging. DJI 65W Portable Charger is recommended before deployment. When fully charged, estimated runtime in Gateway Mode is approx. 2 hours. Charge time (65W PD): approx. 2.5 hours ^{Charging with a 5V charger is only supported when the device is powered off. Charging is only supported when the battery cell temperature is between 0° and 55° C (32° and 131° F).}

Ethernet Port Surge Protection	WAN/LAN Ports: Ethernet interface supports up to 10kA (total discharge current) surge protection, meeting EN/IEC 61643-21 Category C. ^{RJ45 surge protection capacity is 1.5kA (8/20μs waveform), meeting the Category C protection level of EN/IEC 61643-21. Surge protection capability depends on the capacity and reliability of grounding. To minimize the risk of surges, please make sure that grounding is done properly during installation.}
Operating Temperature	IEEE 802.3bt Type 4 (PoE++): -40° to 55° C (-40° to 131° F) IEEE 802.3bt Type 3 (PoE++): -30° to 55° C (-22° to 131° F) IEEE 802.3at Type 2 (PoE+): -20° to 55° C (-4° to 131° F) ^{The 55° C (131° F) upper limit accounts for solar radiation. At -40° C (-40° F), the device requires a windless environment; auto-restart after shutdown is not supported in windy conditions. Cold-weather heating startup requires IEEE 802.3bt Type 3 (PoE++) or above. After storage or operation in extreme temperatures, allow the internal backup battery to return to between 0° and 45° C (32° and 113° F) before charging.}
PoE Auto Wake-Up	When connected to a Type 2 or higher PoE power supply, the device supports automatic wake-up on cable insertion or power restoration.
Cold-Weather Heating Startup	In environments from -40° to -20° C (-40° to -4° F), the device can start up via cold-weather heating mode when powered by a PoE supply of 60 W or above. ^{Requires PoE supply of IEEE 802.3bt Type 3 (PoE++) or above.}
