USING THE RANGEFINDER
7
Measuring range to a small sized target is more difficult than to a large
sized target.
CARE AND MAINTENANCE
Avoid lens contamination. When you are finished using your
binocular, shut the objective protective caps.
Accuracy of measurement can also be affected by light conditions,
fog, haze, rain, snow etc. Ranging performance can degrade in bright
conditions or when ranging towards the sun
.
When measuring range to a small-sized target located more than 400
meters away, it is recommended that you put your elbow against a
solid surface. This is due to possible hand tremors and difficulty in
hitting the target with the beam at a longer distance.
Aim to keep the lenses free of any dirt accumulation, as much as the
conditions allow.
Before cleaning the lenses, blow on them to remove sizable particles
of sand and dust.
When wiping optical surfaces, please use the lens cloth which comes
standard with the set. If a lens cloth cannot be found, you can use any
soft, clean fabric (soft cotton cloth, flannel, silk, or a cotton swab are
best).
Any grease should be removed with a tissue soaked in rubbing
alcohol. In field conditions or if you do not have rubbing alcohol,
breathe right onto the surface of the lens and dry the condensation off
with a soft, clean cloth.
PECULIARITIES OF OPERATION
Accuracy of measurement and maximum range depend on the
reflection ratio of the target surface, the angle at which the emitting
beam falls on the target surface and environmental conditions.
Reflectivity is also affected by surface texture, colour, size and shape
of the target. A shiny or brightly coloured surface is normally more
reflective than a dark surface.
CAUTION!
In order to avoid damaging the lens' coatings, never use paper (dry or
wet) to clean the lens nor apply rubbing alcohol directly onto the lens.
To clean the binocular's exterior, please use a dry tissue. For sheen,
apply a few drops of synthetic cleaning means to the tissue.
The binocular is a sensitive optical instrument; do not drop it.
Safeguard it from any other physical damage.
Do not subject the binocular to prolonged exposure to direct sunlight
or high temperatures.
Do not leave near a heater or heating appliances.
When not in use, keep your binocular in the included carrying case in
a warm, dry, and well-ventilated area.
