USE OF THE ADDITIONAL WEAVER 7/8” RAIL
The riflescope is fitted out with an additional Weaver rail (8) located on the left
side of the body. With the help of this rail you can attach accessories like:
- accessory Pulsar - 940 IR Flashlight (940 nm);
- external power supply EPS3;
- video recorder CVR640 etc.
“Video out” jack (14) is designed to connect external recording devices and
to transmit video signal to monitors, TV sets etc.
Select a suitable video output standard - PAL or NTSC (refer to section
11 “Main Menu”).
Connect an external signal receiver to the “Video out” jack (14) and turn
on the scope.
However please note that higher sensitivity causes an increased noise
level in the picture, lower frame rate; image slows down, if the riflescope
is rapidly moved from one side to the other, the picture may be blurred
for a moment. Neither of these effects is a flaw of the unit. After the
SumLight™ Signal Processing Program is activated, light dots (pixels)
may appear in the field of view which is explained by operation
peculiarities of this function. This is not a defect either.
The riflescope has a number of modes to enhance image quality:
Autocontrast mode and Sum Light™ mode:
Mode “Autocontrast” allows rapid image contrast enhancement (button
(12), marked by icon).
Mode “Sum Light™” activates enhanced sensitivity algorithm for
operation in low light conditions or complete darkness (button (11), marked
by icon).
SumLight™
After the riflescope is switched on for the first time, the Sum Light™
activates automatically. The use of Sum Light™ substantially increases
sensitivity of the CCD array thus enabling observation in low light without
using the IR Illuminator.
When using the unit at a sufficient level of night illumination, the Sum Light™
function can be deactivated manually using the menu. Hereafter on activation
the DFA75 retains the function status before it was turned off.
The wireless remote control duplicates activation of the scope, IR Illuminator
and digital zoom.
“ON” button (23) – turning on/off the scope (keep pressed for two seconds
to turn on the scope);
“IR” button (24) - turning on/off the IR Illuminators, powers settings
selection;
“Zoom” button (25) – activation/deactivation of digital zoom.
The unit has three buttons:
To start using the wireless remote control you will need to activate it:
Turn on the scope and select menu option “RC activation”, marked by
icon in the data panel.
Press the “М” (5) button, a message “WAIT” will show up and countdown
will start within which you need to press any button of the RC.
If the activation is successful, a message “COMPLETE” will show up
next to icon. The RC is ready for use.
If the RC does not work, replace the battery. To do this, unscrew the
screws on the rear panel of the RC, remove the cover, pull out the old
battery and insert a new CR2032 battery.
Indication of hot functions
