These safety precautions are important to the safe operation of this product and should be observed at all times. ·Distinctive Displays The following displays are used to distinguish precautions by the degree of injury of damage that may result if the precaution is ignored. WARNING Items indicated by this display are precautions which if ignored could result in death or serious injury. [. . . ] · When a battery box is removed from the unit, power must be off. If the battery box is removed with power on, it will cause trouble. 13 2. Key Operations and Display 2. 1 Display Vertical angle V=Zenith 0°, V%=Slope(VH=Horizontal 0°, Vc=Compass) Horizontal angle Battery indicator: (HR=right rotation horizontal angle, HL=left rotation horizontal angle) 2. 2 Keyboard [V/%] key [R/L] key [HOLD] key [0SET] key [ (Switches the display of vertical angle) (Set the horizontal angle right and left rotation alternately) (Pressing twice holds the horizontal angle shown on the display) (Pressing twice resets the horizontal angle to 0°, 00', 00") ] Illumination key (Illuminate LCD panel and the telescope reticle) (Turns the power on and off alternately) [ON/OFF] key 14 2. 3 Function of each key 2. 3. 1 Power [ON/OFF] key 1 <Power ON and set the vertical angle 0 point> Pressing the ON/OFF key turns on the power supply and the message "0 SET" is displayed. After the "0 SET" of vertical angle is performed, the Horizontal and Vertical angle are displayed and the instrument enters into the angle measurement mode. 2 <Setting vertical angle 0 point> Set the vertical angle 0 point by turning the telescope upward or downward when the instrument is at the "normal" position (Vertical circle at left. ) <Power OFF> To turn the power supply off, press the ON/OFF key for more than 1 second ("OFF" will display) and then release it. Power turns OFF. 3 15 2. 3. 2 [V/%] key Pressing the V/% key will change the Vertical angle display to V%(slope). (At the shipping, it is set at Zenith 0°) By special key operation, horizontal 0° (VH) and Compass (Vc) can be set. (Factory default is Zenith 0°) (Refer to 3. 1 Setting of vertical angle. ) 16 The error "OVER RANGE" is displayed when the telescope exceeds 45°(100%) in the V% display mode. 17 2. 3. 3 [HOLD] key 1 Press the [HOLD] key twice in succession to hold the displayed horizontal angle and retain it. (Press once, the key buzzer will sound, then press again during the sound. ) 2 Press the key once more to release. To prevent operation error, the buzzer sounds for three seconds when the [HOLD] key is pressed. HOLD is not initiated unless the key is pressed during the buzzer sound. 18 2. 3. 4 [0SET] key 1 Press the [0SET] key twice in succession to reset the displayed horizontal angle 0°, 00', 00" (Press once, the key buzzer will sound, . then press again during the sound. ) 2 Press the key once more to release. (Refer to [4. 6 Object sighting]) 32 4. 6 Object sighting After [4. 5 Eyepiece adjustment] is completed, sight the object. 1 Loosen the telescope clamp screw and horizontal clamp screw. 2 Point the telescope at the object using the collimator sight. 3 Tighten the telescope clamp screw and horizontal clamp screw. 4 Focus on the object by rotating the focusing ring, while looking through the telescope. 5 Accurately align the reticule with the object, using each tangent screw. Collimator Focusing ring object Telescope eyepiece Horizontal clamp screw Horizontal tangent screw · In procedure 4 , focus on the object correctly so that the reticule will not move in relationship to the object when you move your eye slightly left and right, while looking through the eyepiece. · Turn the focusing ring clockwise to focus on a near object. Turn the focusing ring counterclockwise to focus on a far object. · Two screws of the collimator are fixed and adjusted at the distributor or the manufacturer. Do not move them arbitrarily. 33 5. Measurement 5. 1 Horizontal angle measurement (right) 1 2 3 4 5 Level the instrument, and after power on set the vertical angle 0 point. [. . . ] 4 Loosen the telescope clamp screw, and reverse the telescope around the horizontal axis. Mark a point on the line of sight at about the same distance as point B, and call it point C. 5 No adjustment is necessary if point B and C coincide, but if it does not - Consult with your dealer. 41 6. 6 Difference of the vertical angle Inspection 1 Set the vertical angle in Zenith 0° mode 2 Sight an object (Point P) with the telescope and read the vertical angle (V correct). 3 Reverse the telescope and rotate the alidade.
