Yukon PHOTON - Manual (Page 7)

VIDEO OUT JACK
“Video out” jack (10) is designed to connect external recording devices and to transmit video signal to monitors,
TV sets etc.
Connect an external signal source to the “Video out” jack (10) with the supplied video cable.
Turn on the scope – an image will show up on an external device.
ACCESSORIES
With the help of the an additional Weaver rail (13) you can attach accessories like:
Accessory Pulsar-805/Pulsar-940 IR Flashlight (#79071/79076);
Laser IR Illuminator Pulsar L-808S/L-915 (#79072/79075);
External power supply EPS3/EPS5 (#79111/79112);
Video recorder CVR640 (#17044) etc.
MAINTENANCE AND STORAGE
The riflescope features IPX4 degree of protection (protected against splash water) but cannot be submerged
in water.
Attempts to disassemble or repair the scope will void the warranty!
Clean the scope's optical surfaces only if necessary, and use caution. First, remove (by blowing with a blower
brush or canned air) any dust or sand particles. Then proceed to clean by using camera/lens cleaning
equipment approved for use with multicoated lenses. Do not pour the solution directly onto the lens!
The riflescope can be used in operating temperatures ranging from -10 °C... +50 °C. However, if it has been
brought indoors from cold temperatures, do not turn it on for 2 to 3 hours. This will prevent external optical
surfaces from fogging.
Always store the unit in its carrying case in a dry, well-ventilated space. For prolonged storage, remove the
batteries.
TROUBLESHOOTING
Listed below are some potential problems that may occur when using the scope. Carry out the recommended
checks and troubleshooting steps in the order listed. Please note that the table does not list all of the possible
problems. If the problem experienced with the scope is not listed, or if the suggested action meant to correct it
does not resolve the problem, please contact the manufacturer.
possible cause(s) сorrective action problem
The riflescope will not turn on.
The image is too dark.
Poor image quality.
Batteries have been wrongly installed.
Oxidized contact points in the battery
compartment due to “leaky” batteries or
contact points becoming exposed
to a chemically-reactive solution.
The batteries are empty.
Low brightness settings.
Make sure the lenses are not misted
or dirty.
Check that the eyepiece and lens are
adjusted in accordance with the user
manual.
Reinstall the batteries with the correct polarity orientation.
Clean the battery compartment, focusing on the contacts.
Install fresh batteries.
Adjust image brightness by rotating the wheel (9).
Clean the lenses with a cloth wetted in spirit.
Adjust in accordance with the user manual.
9 10
There are several light or black dots
(pixels) on the display of the device. Presence of dots is caused by CMOS chip production technology and is not a defect.
Barely visible texture which does not impact
detection range and efficiency of observation
can be noticed on the display after the built-in
laser IR Illuminator is activated. This is normal for eye safe laser illuminators.
Peculiarities of CMOS array
CMOS arrays employed in Yukon digital night vision devices, feature high quality. However certain pixels (or groups of pixels) with increased
luminosity (lighter or darker) are allowed. These defects can be seen when conducting observation not only in the nighttime but in the day
time too, especially if SumLight function is active. Presence of light and dark pixels and other minor defects of a CMOS array (up to 4%) are
acceptable in accordance with regulations of the producer. Visibility on the screen of light pixels also depends on the type of CMOS array,heating
temperature during operation.
