3 The symbol of the inner lens and theirs functions
3.1 Symbol for aim: "--|-- ", in which center there is a circle that used while measuring.
3.2 Distance— Displaying: A there-figure number just above the field of vision; It displays " — " when there is no distance.
3.3 Distance unit: "METERS" (m) or "YARDS"(yd).
3.4 The model of distance— Measuring: On the left above the field of vision:
(1) No letter displayed— Standard condition;
(2) "RAIN"----for rainy days to measure distance when the objects beyond 60 meters;
(3)"REFL"--- fit for thin— Foggy and heavy— Steam day;
(4) ">150"---- there are interfering objects (electrical wires, branches, etc)within 150m, which the objective must beyond.
3.5 The quality of the distance— Measuring: It shows with "QUALITY"just under the field of vision, when six ""(or more than six) show, the return-wave is strong enough for the distance-displaying.
3.6 Laser emission: It shows with "LASER" on the left under the field of vision. When emitting the laser, the "LASER" glitters.
3.7 The battery is lack of voltage: When "BATT" is displayed, it means that the voltage is not enough, and the battery needs to be changed.

4. The operation of distance-measuring
4.1 Adjust the eyepiece degree of the telescope to make the object clear in the field of vision.
4.2 Click the "triggering" button, in the lens displays "+", then aim the centre circle at the object. The item of "model" is usually on the standard condition. Re-click the "triggering" button and keep pressing it for about three seconds, then it will displays the distance of the object. It would shut off automatically if it is not used in fifteen seconds.
4.3 In order to measure back the object dependably, keep pressing the "trigger" button for mare the three seconds till the distance of the object display for the second time, but should not keep pressing for long time, or it will display the decimal of the causing. If there is still no distance displayed after three seconds, which indicates that the character of the wave is bad, then "-"displays.
4.4 The condition may change the "model" button. The use of each model should be chosen according to the directions of the item 3.5. When switching the electric power on, it is in the model condition of the last time.
4.5 If the distance unit needs to be switched, keep pressing "model" for more than three seconds.

5. Points for attention while using
5.1 Don't take apart the telescope in order not to damage the inner electric circuit.
5.2 Don't cleanse the outside of the lens with hands, please cleanse the lens with appropriate lens-cloth. The outside lens should be cleansed with soft cloth.
5.3 Don't invert the battery.
5.4 The battery should be taken out if the DMT isn't in use for a long time.
5.5 It should be put in a dry place when not in use.
5.6 It should be used when the temperature is between -20º C---40º C.
