All batteries discharge over time when not in use, and they discharge faster in colder temperatures.
Do not store the receiver at temperatures outside the range –40 °C to +70 °C (–40 °F to +158 °F).
Do not store the receiver at temperatures outside the range –40 °C to +70 °C (–40 °F to +158 °F).
Power over Ethernet (PoE)
The receiver is a PoE-capable device and can be powered using a single Ethernet cable from an
IEE802.3af capable network using one of the following cables/adaptors:
IEE802.3af capable network using one of the following cables/adaptors:
• 57168
• 65791-00, 78235-00
• 65791-00, 78235-00
Warning – This product is not intended to be used outdoors or in a wet location when it is powered by
the POE interface, or by the external power supply. The product should only be used in these types of
environments when operating on its own internal battery.

environments when operating on its own internal battery.
Warning – When this product is connected to a PoE connection, the source of the Ethernet power must
meet IEEE 802.11af, and its DC output (Ethernet power source) must be completely isolated from earth
ground (floating), or a shock hazard may exist.

External power
Sources of external power include:
• AC power
• 12 V car or truck battery
• Trimble custom external battery pack
• Generator power
• Solar panel
The GPS receiver uses an external power source in preference to its internal batteries. If the receiver
is not connected to an external power source, or if the external power supply fails, the internal
batteries are used.

While carrying out static measurements for postprocessed computations using the internal memory, if
no external power is supplied and the internal battery is drained, the receiver shuts down. No data is
lost and when power is restored, the receiver restarts in the same status as it was when power was
lost.

It is possible to turn off the internal battery using the web interface. In this case, when external power
is switched off, there is a limited time (30 seconds) before the unit turns off.
