SAFETY SUMMARY
• Read and follow all instructions
• Read all warnings
• Only use the attachments/accessories specified by the manufacturer
• All service must be provided by the manufacturer
WARNING:
This product contains natural rubber latex which may cause allergic reactions! The FDA has

natural latex proteins. If you are allergic to latex, it is a good idea to learn which products contain
it and strictly avoid exposure to those products.
WARNING:
Do not watch the sun directly by using binoculars to avoid harming your eyes.
CAUTION:
• The binoculars are a precision optical instrument, and must be handled carefully at all times to
prevent damage to the device.
• The unit may be badly damaged if the tripod on which it is mounted collapses or overturns.
Remove the unit from the tripod if it is not within your reach.
• Do not turn the diopter adjustment handwheel in overexerting, stop to turn when it reach the
limited position, otherwise the eyepieces assembly will be damaged!
• Be careful to move the binoculars to avoid overexertion or collision.
• To avoid the heavy vibration when you take it.
• Thoroughly dry each component of the binoculars before placing them in the storage case.
NOTES:
For the purpose of returning defective components, retain all packaging materials.

2.2 INTERPUPILLARY ADJUSTMENT
You must first adjust the binoculars so that each eye piece is adjusted to the distance between
your eyes. This is done by putting the binoculars in both hands and bending it until you can see a
single circular image.
2.3 DIOPTER ADJUSTMENT
To watch the object by handing the binoculars, you will need to close your left eye. Rotate the right
diopter adjustment rings until the object image appears sharp and clear in your right eye opening.
Then open you left eye and close right eye, rotate the left diopter adjustment rings until the object
image appears sharp and clear in your left eye opening. Then can get a perfect viewing.

2.4 RETICLE USING
2.4.1 BINOCULARS RANGEFINDER RETICLES
The reticle has horizontal scale and vertical scale, in the below there is measuring reticule
according to the known height (see Figure 4). Vertical and horizontal lines on the reticule is in mils
as unit. Each small division on both vertical and horizontal lines represents 5 mils and each big
division represents 10 mils. You can obtain the azimuth angle, upper and lower angle, distance and
height or width etc. by using this reticle. The fast distance measurement is regards as the target
as 2 meters high to measure the distance quickly.
2.4.2 HOW TO USE THE RETICLE AND CALCULATOR DIAL
1) How to Measure the Horizontal View Angle
The azimuth angles are the angle included between two objects to be measured at the horizontal
direction of the binoculars.
A. When the Horizontal View Angle is smaller than the horizontal scale range (-40~+40 mils) inside
the binoculars, aim one edge of the object at a horizontal scale line(the center or the outmost
line are selected according to the image size of object usually) and read its value. Then read the
value of the scale at which another edge was located. Add these two values, the sum value is the
measured Horizontal View Angle. As shown in Figure 5, the Horizontal View Angle of the target
(tank) is 20-00 mils, and the Horizontal View Angle is 20 mils.

FIGURE 5. HORIZONTAL VIEW ANGLE MEASURING

98x36 USER MANUAL
B. When the Horizontal View Angle is bigger than the horizontal scale range (-40~+40 mils), a
vertical line splits(for example: mast, chimney etc.) on the object can be selected to make the
necessary estimated measurements in a step by step fashion. The sum of the value from each
step is used to obtain the measured value. As shown in Figure 6, the azimuth of target (cruiser) is
110 mils (60+50=110).
2) How to Measure the Vertical View Angle
Upper and lower angle means the angel included between any two targets (or two ends of the
target) against the vertical line on the reticle.
A. Vertical View Angle measurement is similar to measuring the Horizontal View Angle. When
the Vertical View Angle measurement is small, aim the cross center of reticle at lower part of the
object, read the scale value at the top of the object. If the target vertical angle is a little bigger, you
can read the upper scale and the lower scale. As shown in Figure 7, the upper line is 35 mils, and
the lower line is 40 mils, the total vertical angle is 75 mils.
B. When the Vertical View Angle is larger than the vertical scale range (-40 to +40 mils), it can be
measured in steps and the angle can be obtained by summing up the value of each step. (The
process will be similar to the measurements as mentioned above as horizontal view angle.)

3) How to Use the Reticle to Measure Distance.
The distance measurement of a target can be calculated by using the mil reticule.
The formula of distance measurement: L(km)= H (m)/ω
L — the distance between the observer and the object (km)
H — the height of the object (m)
ω — the view angle of the object measured with the reticule of binoculars (mil).
When measure the distance, first, estimate the width or height of the object, then measure the
View Angle of the object. According, you can calculate the distance between the observer and the
object using the formula.
For example 1:
There is a lighthouse height is 25 m (H = 25 m).
The Vertical View Angle of the adult is 6 decade mils (60 mils).
L = H/ω = 25/60 = 0.4166 km = 416.6 m
Therefore: the distance between the observer and the adult is 416.6 m.
For example 2:
There is an adult whose height is 1.70m (H = 1.70 m).
The Vertical View Angle of the adult is 4 decade mils (40 mils).
L = H/ω = 1.7/40 = 0.0425 km = 42.5 m
Therefore: the distance between the observer and the adult is 42.5 m.
4) How to Measure an Object’s Size (Height and Width) Using
According to the formula for distance measurement, you can calculate the height using:
H = L × ω.
When measuring the size, you first estimate the distance to the object, then measure the View
Angle. With these measurements, you can calculate the height of the target using the formula.
For example:
The distance is 0.6 km between the observer and the object. You can measure that the Horizontal
View Angle is 6 decade mils (60mils) and the Vertical View Angle is 3 decade (30 mils). So, using
the formula you can get:
The height: H = 0.6 × 30 = 18 m
The width: h=0.6 × 60=36 m
