Please note that the movement of the vial becomes opposite direction if it sees at the position of ..Right circle position". .. When instrument is within the tilt compensation range, length and sidewise..3', “ON” is displayed at the right screen, “ OVER” is displayed beyond the limits of range and “NIL” is displayed at no compensation setting. .. With command No "520" or "Initial setting 2", when the [TILT DISP] is selected as ON, the [F1 -TILT] of the vial screen becomes effective.

Turn two Leveling screws arbitrarily chosen in an opposite direction mutually and put the vial of the horizontal Electronic vial in the center. (Figure A) ................ Put the vial of the lengthwise Electronic vial in the center by operating the Leveling screw of one remainder. (Figure B) ................ The procedures are different according to the state of the Automatic inclination correction. [When using the Automatic inclination correction by 2 axes ] Please read procedure .. because the horizontal angle and the perpendicular angle error by a perpendicular axis are automatically corrected. [When using the Automatic inclination correction by 1 axis ] The instrument is horizontally rotated by 180 degrees after the vial of an Electronic vial is adjusted on the center at a Left circle position side and confirm that the vial of the vial is at the center at the right circle position. [When using the Automatic inclination correction by 0 axis ] ................ Confirm the vial is at the center even if the instrument is rotated by each 90...Confirm whether the instrument is on the ground mark. When you can confirm it is just on the mark loosen the center screw and move the instrument on the ground mark correctly and fix the instrument by a center screw. Repeat from .. to ... 3-6 Eyepiece Adjustment Eyepiece adjustment The eyepiece adjustment is performed before target sighting. ................ Remove the telescope lens cap. ................ Point the telescope at a bright object, and rotate the eyepiece ring full counter-clockwise. ................ Look through the eyepiece, and rotate the eyepiece ring clockwise until the reticle appears as its maximum sharpness. .. When looking into the eyepiece, avoid an intense look to prevent parallax and eye fatigue. ..When it is hard to see the reticle due to poor brightness, press Illumination key to illuminate it . For adjusting intensity of brightness, refer to page X. Leveling screw P21 3 PREPARATION FOR SURVEYING........ [Target sighting by Auto focus] The Auto focus of R-300 series has following two modes. 1. Normal mode : Pressing AF button focuses on the target. 2. Continuous mode : Pressing AF buttons for two seconds beeps, and releasing the key enters into the Continuous mode. This mode enables you to perform the Auto focus approx. for one minutes only by sighting the telescope and chasing the target. 3 PREPARATION FOR SURVEYING [Auto focus :Target sighting by Normal mode] q Loosen the telescope clamp and horizontal clamp screws. w Point the telescope at the target using a collimator. e Tighten the above two screws. r Adjust the eyepiece. t Look through the telescope and press the AF button.
