Set the tripod and fix the metal shoes firmly into the ground so that the tripod head is as level as possible, and the Tripod head coincides with the station on the ground. Fasten the leg screws. ................ If the tripod head is mis-leveled by the action of fixing the metal shoes into the ground, correct the level by extending or retracting each leg of the tripod... 3 PREPARATION FOR SURVEYING 3-2 Laser plummet Laser plummet model The laser plummet is not set to be ON at factory shipping.

3.7 Target sighting [Auto focus] The Auto focus mechanism is very precise but will not function under every condition. There is a slight possibility of focusing failure owing to brightness, contrast, the shape and size of the target. In such a case, press the AF button and focus on the target by operating the Power focus key or the AF ring. No contrast like a white wall Bright back light Obstacle in front of a target A wall composed of single horizontal
