sliding the eyepieces closer together or farther apart. Remove the lens cover from the front of the objective
lens. Remove the lens cover from the front of the objective lens. Note: since the device uses digital night
vision technology (not analog "Gen 1", etc.), the unit cannot be damaged by exposure to normal indoor or
outdoor light levels-however, you should avoid pointing it directly at the sun or other very bright light
sources to avoid overloading the sensor.
3) TURN ON IR LIGHT (IF NEEDED), ADJUST OBJECTIVE LENS FOCUS FOR SUBJECT DISTANCE
If the image is too dark to easily view (in most building interiors, and outdoors when away from artificial lighting),
press the IR button to turn on the Infrared LED light. If the image is too bright after turning on the IR light (when
viewing at close range), press the IR button again to reduce the IR light level. If the image is still too dark after
turning on the IR light, try pressing the Image Brightness button once or twice to lower the frame rate of the
digital sensor. If the image is not sharp, rotate the center Focus knob to change the focus until the subject
appears sharp. Do not re-adjust the Display (Eyepiece) Focus (as set in Step 2), unless the display icons are
un-sharp.

OTHER OPERATIONS

AUTO POWER OFF
If a button has not been pressed for 10 minutes, the display screen will drop to 50% brightness level. If no
button is pressed within one minute after that, the unit will power off to extend battery life. Pressing any button
quickly any time before the unit turns off will return the screen to full brightness level and reset the auto off
countdown process, without changing any other settings
ICON OVERLAY ON/OFF
The user has the option to control how the icons are displayed on the LCD screen. Normally, when any button
is first pressed, ALL icons are displayed for 5 seconds, but no change to the unit's settings is made (the
Record and IR buttons is an exception-image capture begins immediately the first time "Record" is pressed,
and the IR light turns on at the first press of "IR"). If the same button is pressed again, the button performs its
function, and the display icons remain visible for 10 seconds after the last press, before turning off
automatically. To display all icons constantly, press and hold the IR button for 3 seconds. Repeat to switch
back to auto icon overlay (only visible for 10 sec. max following the use of a button)
USING THE DIGITAL ZOOM
Press the "+" button (B) to zoom in. Press the "-" button (B) to zoom out. Hold the button down to zoom in/out
rapidly. The Digital Zoom icon at the lower left corner of the display will indicate the magnification factor, from
1.0x to 5.0x (in 0.1x increments).
SELECTING PAL OR NTSC VIDEO OUTPUT
The Video Output jack is set to NTSC format (30fps TV standard in the USA, Canada, Mexico, etc.) by default.
To select PAL video output (25fps) format as used in other countries, connect the unit to your video device
first, then hold both the IR button and Image Brightness buttons down for 5 seconds while viewing the display
through the eyepiece. When the display changes to "PAL", release buttons. To switch back to NTSC video
output format, hold both buttons for 5 seconds until the display indicates "NTSC", then release the buttons.
Note: The "Auto Off" feature is disabled when using the Video Output jack.
