2.OPERATION INSTRUCTIONS

Focus adjustment

Rotating the eyepiece until the reticle and object display to your eye clearly.

GX-2S range finder is constructed with an adjustable eyepiece (+/-3 Diopter). People with different visions don’t need to wear glasses, they can observe LCD with naked eyes.

Units switch

To select yard and meter, just press and release "M" button quickly to change" Y"(yard) and "m" (meter).

The GX-2S range finder can be used to measure distances in yard or meter. The unit of measure indicators are located in the lower right portion of the LCD.

Slope switch function

To select yard and meter, just press and release "M" button quickly to change" Y"(yard) and "m" (meter).

The GX-2S range finder can be used to measure distances in yard or meter. The unit of measure indicators are located in the lower right portion of the LCD.

Slope switch function

Pressing "M" button that is units switching button and hold it for approximately 3 seconds.The data displayed at the top will disappear, leaving only a straight line distance on the LCD, which is designed for golf games. If you want to turn on the slope mode, just press the "M" button again for 3 seconds.

Range mode

1.Look at LCD through the eyepiece, then press Power button and release quickly, you will see the display as right picture. Pressing Power button again to measure.
(The laser rangefinder will auto power-off if no operation within 8 seconds.)
2.Placing the aiming circle (located in the center of view) on a target over than 6 yards away, press Power button and release quickly. The range and angle, slope reading will be displayed on LCD.

LCD data shows：Line of sight distance until auto power-off.
(Straight-line distance is 20.82 yards, angle is 4.9 degrees, and slope is 22 yards.)
For the slope of uphill / downhill slope. Please refer to Page 12 "GOLF MODE EXAMPLE".

3.Tips: When the target’s background is single or the target is large, just need use RANGE MODE that click the “Power button” to measure; When the target background is complicated or it is difficult to measure the distance by clicking Power button, you can use SCAN MODE/FLAG LOCK MODE.
4.Tips: SCAN MODE/FLAG LOCK MODE is recommended when measuring the flag on golf courses.

Scan mode (WITHOUT PULSE VIBRATION HAPPEN)

Long press the“POWER” button align flag to scan, you will get distance without pulse feeling.

Flag lock mode (WITH PULSE VIBRATION HAPPEN)

Flag lock mode sign: After you lock onto flag successfully, the circle on flag sign will shows. (Like image shows)

Method: Pressing “POWER” button and scan from far to flag, at the same time, the “Scan” icon will flash and the circle on the flag will show,you will get distance and feel vibration.

6.HOW TO WORK AND RANGING ACCURACY

The GX-2S range finder emits invisible, eye safe, infrared energy pulses. Sophisticated digital technology instantaneously calculates distances by measuring the time, which it takes for each pulse to travel from the rangefinder to the target and back to rangefinder.
The color, surface smoothness, size and sharpness of target will affect its reflectivity and range.
It is difficult to test in the following conditions and environments:
Raining or fogging / Target is too small / Low reflectivity of the measured object (dark color, complex shape, curved surface, water surface, glass surface, mirror surface. etc.) / Low battery.

7.RAEDY TO START

Remove the battery cap by rotating the cap counter-clockwise.
Insert a CR2-3V battery.
Put the negative pole of lithium battery into battery compartment first.
Replace the battery cap.

Display	Description
	Sufficient power available
	60%power left.
	Low battery indicator flash: Replace the battery now! *It can be turned on, but it can’t shows any data. Meanwhile, vibration will be paused.

Note: It is recommended that the battery should be replaced once every 12 months.

Notice: Replace the battery when Low battery indicator shows.

If the “ ” displays and flash on LCD, which means “low battery”. It can be turned on, but it can’t shows any data. Meanwhile, vibration will be paused.

Install/Change battery

Open the cap counter-clockwise
The positive pole "+"of the lithium batteryCR2 should be placed outwards. (look atthe picture)
Tighteningthe battery cap clockwise after installing the battery.

8.GOLF MODE EXAMPLE

Distance measurement of ascending slope: Slope is farther than the straight-line distance.

Distance between AB points=distance between AD points in a straight-line 99.71Y.Hit the ball in accordance with the distance measured with the strike parabola 1, the angle of slope is + 6.2 °, and the ball will arrive at the point C. To reach the point B,the trajectory of the ball needs to follow the parabola 2. The actual hitting distance at this time is the straight-line distance between point A and point E, i.e. 108Y.

Distance measurement of downward slope: Slope is less than the straight-line distance.

Distance between AB points = distance between AD points in a straight-line 216.01Y. Hit the ball in accordance with the measured distance with the strike parabola 2, the angle of slope is -12.1 °, the ball will arrive at the point C.To reach the point B,the trajectory of the ball needs to follow the parabola 1. The actual hitting distance at this time is the straight-line distance between point A and point E, i.e. 170Y.
