Observation with and without glasses
When observing
without
glasses, use the equipment with the eye cup extended. To do this,
turn the eye cup
(Fig. 1/1)
upwards and to the left (anticlockwise) until it locks in the highest
position
(illustration A)
.
The eye cup
can be locked
in four positions – in the upper and lower plus in two intermediate
positions. This adjustment option allows variation of the distance from the eye to the exit pupil
and thus individual adjustment for each user.
When observing
with
glasses, turn the eye cup downwards and to the right (clockwise) until it
locks in the lowest position
(illustration B)
.
Focusing the aiming mark
Use the RANGE FINDER button
(Fig. 1/3)
to switch on the aiming mark
(Fig. 4/9)
and hold
down the button. Focus the aiming mark and the display
(Fig. 4/10)
by turning the diopter
compensation (
Fig. 1/2)
to the left or the right.
Metre/Yard switching
The range can be displayed either in metres or in yards, as desired. To change the setting, use the
SET button
(Fig. 1/4)
. A short press of the SET button will display the setting currently selected.
An extended press of the button for over 3 seconds will cause the display to start to flash and the
setting to then change every time the SET button is pressed.
All settings preset for the
EU
represent range displays in metres; all settings preset for the
US
represent range displays in yards. The selection of setting EU 0 (display in metres) or US 0 (display
in yards) is preferable for the basic use. The other settings, EU 1 to EU 6 and US 1 to US 6, are
described in the chapter on the
Ballistic Information System
.

Range estimation
Press
the RANGE FINDER button
(Fig. 1/3)
to switch on the aiming mark
(Fig. 4/9)
. The object
to be measured is sighted using the aiming mark. Release the RANGE FINDER button
(Fig. 1/3)
to start the measurement. After a maximum of approx. 4 seconds, the estimated range is shown
on the display for approx. 3 seconds
(Fig. 4/10)
.
Should it not be possible to take a measurement because the range has been exceeded or
because the reflection from the object is insufficient, this will be shown by 4 dashes: “– – – –”. A
fresh measurement can be taken immediately.
The brightness of the display is automatically adjusted to the brightness of the surroundings
and therefore requires no manual adjustment. The range finder switches off automatically when
the display goes off.
Scan mode
The equipment can also be used to measure in constant operation (scan mode). If the range finder
button
(Fig. 1/3)
is pressed for longer than approx. 3 seconds, the equipment switches to scan
mode and takes measurements continuously. This can then be seen from the range display, which
emits new measuring values approx. every 1.5 seconds. The scan mode is helpful for measuring
small or moving targets.
Note:
Scan mode switches off automatically after approx. 40 seconds in order to save the battery
in case the button is pressed accidentally.
Range estimation accuracy
The range finder is accurate to +/– 1 metre/yard. The maximum range according to the technical
specifications is achieved in favourable environmental conditions.
The following environmental factors affect the range:
Higher range with
Lower range with
Atmospheric condition
Clear visibility
Haze, fog
Brightness
Low brightness (twilight)
High brightness (sunshine)
Object colour
White object colour
Black object colour
Angle to the object
90° (perpendicular) angle
Sharp angle
Object structure
Homogeneous structure
(sign, wall)
Inhomogeneous structure
(bush, tree)
