This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
Caution: Changes or modifications to this unit not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
—Consult the dealer or an experienced radio/TV technician for help.
MPE caution
To satisfy FCC RF exposure requirements, a separation distance of 20 cm or more should be
maintained between the antenna of this device and persons during device operation.
To ensure compliance, operations at closer than this distance is not recommended
User Safety
WARNING:
Carefully read the Safety Instructions and Product Manual before using this
product. The person responsible for the instrument must ensure that all
users understand and adhere to these instructions.

1. Use of instrument
The total station is such an instrument that measures the azimuth
and distances to destination and can calculate the destination point
coordinates automatically. It plays an important role in the economic
construction and national defense construction. General Survey,
exploration and mining of minerals, the construction of railways,
roads, bridges, irrigation, urban planning and construction is driven
by electronic total station measurements. In the building of national
defense, such as battlefield preparations, harbor, forts, airfields, bases
and military construction projects, and so on, must be based on a
detailed and accurate geodetic. In recent years, electronic total station
is a large precision engineering, shipbuilding and aviation industries
and other aspects of effective tools for precise positioning and
installation.
The series total station is equipped with absolute code dial
system, integrated-circuit-control-board ranging item and
microcomputer for measurements of angle and distance and for
calculation, display, depositing and etc. It can exhibit horizontal and
vertical angle, slope and horizontal distance and altitude difference
simultaneously. Furthermore, it can be set to measure under different
mode (e.g. Angle mode, Distance mode).It is even designed for you
specializing in construction projects with non-prism ranging. The
non-prism ranging can be comprehensively used in measuring
three-dimensional coordinates, position determination, remote
elevation measurement (REM), verticality, pipeline positioning,
cross-section measurement etc. It also meets requirements for
trigonometrical control survey, topographic survey, cadastre and real
estate survey.

or damage due to unauthorized service repairs made by someone
other than Northwest or other Northwest authorized service personnel.
Circumstances beyond Northwest Instrument s control cannot be
warranted.
B. This warranty does not apply to regular required maintenance such
as cleaning, adjusting, lubricating or calibrating unless required as a
result of a defect in workmanship or materials. If, upon examination
of the instrument, NWI determines that additional repair services are
required and not covered under this warranty, NWI shall notify the
Buyer of such repair charges and proceed only after authorization has
been received.
C. This warranty does not apply to instruments damaged in transit to
or from Northwest Instrument or any authorized repair center.

2.3.4 Explanation of saving data
If you have never selected the measurement file and your first
time to use the [Save] soft key, a dialogue box of ‗Select file‘ would
appear to the screen. Mention that this is a good chance for you to
select all files that the instrument may use.
When finishing single measurement, a dialogue box asks you to
save the measured point and you may rename and code the points or
set target height. The key ‗ENT‘ will save the coordinates into
measurement files, and the key [★] save the coordinates in the
measurement file and coordinate file at the same time (according to
the mention of the display).
If you choose not to edit points, the points would be saved with
the present name, elevation and code .After saving, the name of the
point is added by one.
