3. Locate an object within 20 to 30 meters.

4. Rotate the lever of the eyepiece (7) until you clearly see the frame of the display and black fine grid on it. Adjust the sensitivity of the device (visually it is determined as image brightness) by turning the adjustment wheel (11).

5. Rotate the objective (4) until you see a sharp image of the object. When you turn the device on, the stealth short-range IR-illuminator is turned on automatically. Press the «IR» button (8) to turn the main long-range IR-illuminator on. Choose the operation modes of the IR-illuminator: press and hold the «+» (9) or «-» (10) buttons to increase or decrease respectively the power of the IR-illuminator. The use of the IR-illuminator in the optimal mode prolongs operating time. If the device is focused on an object closer than 15 metres, the emission spot of the main IR-illuminator (bright light circle) will be shifted to the right side of the display.

6. When changing the viewing distance, try to see a sharp and high-quality image by rotating the objective (4) and the sensitivity adjustment wheel (11) and by changing the operating modes of the IR-illuminator. Do not rotate the eyepiece's lever (7)  the device is already individually adjusted.

7. Plug the output video cable into the RANGER PRO's video-output jack (12) to transmit the observed image to an external LCD monitor. When the RANGER PRO 5x42 is coupled with video equipment, the observed image can be recorded.

8. To connect the RANGER PRO 5x42 to a vehicle's 12V auxiliary power port, plug the car adapter into the RANGER PRO’s power input jack (13) and connect the other end of the cable to the vehicle's auxiliary power port.

9. To connect the RANGER PRO 5x42 to a household outlet, use a variable power switching adapter. 

Be careful, observe the polarity shown on the inner side of the battery cover.

NOTE. When the batteries are in the container and the external power source is turned on, the device operates on the external power source. If you unplug the external power source, you have to press the «ON» button to make the device operate on the batteries.
