General Handling Precautions Before starting work or operation, be sure to check that the instrument is functioning correctly with normal performance. Do not submerge the instrument into water. The instrument can not be submerged underwater.
FOREWORD Rotating the instrument and telescope Rotation of the instrument or telescope is driven electronically in normal operation. Do not disturb the rotation. Storage in the case Keep the telescope horizontally and turn the instrument to align its mark with the lower base mark (Storage mark). Keep its objective lens side downward. Storing it in the case in any other way may cause damage.
FOREWORD Display for Safe Use In order to encourage the safe use of products and prevent any danger to the operator and others or damage to properties, important warnings are put on the products and inserted in the instruction manuals. We suggest that everyone understand the meaning of the following displays and icons before reading the “Safety Cautions” and text Display Meaning WARNING Ignoring or disregard of this display may lead to the danger of death or serious injury.
FOREWORD CAUTION Use of controls or adjustment or performance of procedures other than those specified herein may result in hazardous radiation exposure. Let the laser beam reach the aimed object or the target without anybody else in the laser beam path. In case you operate laser beam open, avoid radiating laser beam to the height of man's head.

3 AUTOMATIC TRACKING / AUTOMATIC COLLIMATION 3.2 Automatic Collimation The function enables to collimate automatically so that the instrument searches for the center of the prism when the telescopic is aimed a prism roughly. Use this mode for the object which is stable. l You can select Fine or Course mode for the distance measurement in auto-collimation. Operating procedure Option 1 Manually collimate the target prism roughly Display V : 87°55'45" HR: 180°44'12" using V/H jog/shuttle.
3 AUTOMATIC TRACKING / AUTOMATIC COLLIMATION 3.3 Range of Laser for Auto-tracking and Auto-collimating The range of laser at the long distance is within ±30' as shown in following. So you had better collimate the prism so that the prism may be located within this range of laser in the first step. As for it, rapid automatic collimating and automatic tracking becomes possible. If the target prism is out of this range, time for searching mode will be necessary.

9 CHECK AND ADJUSTMENT 9 CHECK AND ADJUSTMENT 9.1 Checking and Adjusting of Instrument Constant Normally, the instrument constant does not have discrepancy. It is recommended you measure and compare with an accurately measured distance at a location where the precision is specifically monitored on a consistent basis. If such a location is not available, establish your own base line over 20m (when purchasing the instrument) and compare with the data measured with newly purchased instrument.
9 CHECK AND ADJUSTMENT 9.2 Checking the Optical Axis To check if the optical axis of EDM and theodolite are matched, follow the procedure below. It is especially important to check after adjustment of the eyepiece reticle is carried out. 1) Position a prism about 30 to 50m apart from GTS-820A series. 2) After the power switch ON of GTS-820A series, collimate the center of the prism. 3) Press the soft key (Set audio) in the star key mode. Buzzer sounds continuously.
9 CHECK AND ADJUSTMENT Vertical direction confirmation (Do not move Horizontal direction). 13) Carry out as Horizontal direction confirmation. Compare the reading Vertical angle value and calculated value. If the difference is within 1’ 30”, no problem for use. If the difference is more than mentioned value, contact with your Topcon dealer or Topcon.
9 CHECK AND ADJUSTMENT 9.3 Checking/Adjusting the Theodolite Functions l Pointers on the Adjustment 1) Adjust the eyepiece of the telescope properly prior to any checking operation which involves sighting through the telescope. Remember to focus properly, with parallax completely eliminated. 2) Carry out the adjustments in the order of item numbers, as the adjustments are dependent one upon another. Adjustments carried out in the wrong sequence may even nullify previous adjustment.
9 CHECK AND ADJUSTMENT 9.3.1 Checking /Adjusting the Plate Level Adjustment is required if the axis of the plate level is not perpendicular to the vertical axis. l Check 1) Place the plate level parallel to a line running through the centers of two leveling screws, say, A and B. Use these two leveling screws only and place the bubble in the center of the plate level. 2) Rotate the instrument 180° or 200g around the vertical axis and check bubble movement of the plate level.
9 CHECK AND ADJUSTMENT 9.3.3 Adjustment of the Vertical Cross-hair Adjustment is required if the vertical cross-hair is not in a place perpendicular to the horizontal axis of the telescope (since it must be possible to use any point on the hair for measuring horizontal angles or vertically running lines). l Check 1) Set the instrument on the tripod and carefully level it. 2) Sight the cross-hairs on a well defined Point A at a distance of, at least, 50 meters (160ft.).
9 CHECK AND ADJUSTMENT 9.3.4 Collimation of the Instrument Collimation is required to make the line of sight of the telescope perpendicular to the horizontal axis of the instrument, otherwise, it will not be possible to extend a straight line by direct means. l Check Eyepiece 1) Set the instrument up with clear sights of about 50 to 60meters (160 to 200 ft.) on both sides of the instrument. 2) Level the instrument properly with the plate level. 3) Sight Point A at approximately 50 meters (160 ft.
9 CHECK AND ADJUSTMENT Note: 1 2 First, loosen the capstan adjustment screw on the side to which the vertical cross-hair line must be moved. Then tighten the adjustment screw on the opposite side by an equal amount which will leave the tension of the adjustment screws unchanged. Revolve in the counterclockwise direction to loosen and in the clockwise direction to tighten, but revolve as little as possible. Perform following adjustment after complete above adjustment. Section 9.

APPENDIX APPENDIX 1 Dual Axis Compensation Inclination of the vertical axis with respect to true vertical will result in incorrectly measured horizontal angles. The extent of the error in horizontal angle measurement due to axis tilt depends on three factors : l l l the amount of the tilt of axis the elevation of the target the horizontal angle between the direction of tilt of the vertical axis and the target.
APPENDIX It is clear from the table that dual axis compensation has the most benefit when the elevation of the target is greater then 30° and the axis is tilted more than 10". The entries indicated in bold in the table show, in fact, that for many common surveying applications i.e. target elevation <30° and axis error <10", virtually no correction would be required. Dual axis compensation is especially suited then for applications where the sights are very steep.
APPENDIX 2 Precaution when Charging or Storing Batteries The capacity of battery will be affected and its service life shortened in any of the following cases while it is recharged, discharged or stored. 1) Recharging Fig. 1 shows how ambient temperature at recharging is related to charging efficiency or as affecting discharge capacity. As seen from the figure, charging at normal temperature is best, and the efficiency decreases as the temperature rises.
