cellular communications tower.
 Do not set up the base station close to the sources of electromagnetic
interference, include alternators and generators, electric motors,
equipment with DC-to-AC converters, etc.
 Do not operate the receiver outside the specified operating
temperature range -40°C to +60°C (-40°F to +140°F).
 Take reasonable care to keep the GNSS receiver equipment dry, which
could prolong their life and reduce the effects of corrosion on ports and
connectors.

3. Mount the tribrach onto the tripod.
4. Insert the tribrach adaptor into the tribrach.
5. Level and plumb the receiver over the known (control) point.
6. Measure the height of the base station GNSS antenna by measuring the
slant height from the known (control) point to the end of auxiliary H.I.
tool.
Note –After entered the vertical height from the known (control) point to the
bottom of receiver that you calculated by adding the height of the extension
pole to the height from the known (control) point to the auxiliary H.I. tool,
LandStar 7 will calculate the height to the Antenna Phase Center (APC)
automatically.
7. If required, connect the receiver to an external 12 V power supply.
