The internal battery will operate from –20 °C to +50 °C (–4 °F to +122 °F). The internal battery charger will
operate from 0 °C to 40 °C (32 °F to 104 °F).
2
Accuracy may be subject to degradation by multipath interference, obstructions, satellite geometry and
atmospheric conditions. Always follow recommended survey practices.
3
Depends on WAAS/EGNOS system performance.
4
Alloy limited to 1,000 m RTK baseline length.
5
Networked RTK PPM values are referenced to the closest physical base station.
