NOTE:
We suggest that you focus the diopter during daylight with the filter on.
Next focus the front lens until the image and the grain are both sharp. When you are in low-light con-
ditions and the daylight filter is off, you may focus the front lens to receive sharp image, the diopter
should not be adjusted.
NOTE:
The front lens should be readjusted as you view objects at different distances.
InfRa-RED IllumInatoR
Infra-red illuminators, or IR illuminators, are common to night vision.
The IR light greatly enhances the performance of the PS-23 while
remaining almost totally invisible to the naked eye.
To turn the IR on, draw and rotate the operation knob to “IR” posi-
tion.
It is important to remember that the IR illuminator is simply an infra
red light source, and like any light source, it may loose its effective-
ness over a great distance.

PRotEctIvE SyStEm
The automatic highlight protective system analyzes light exposure with the sensor . If the level of
light exposure exceeds allowable the red indicator will turn on. If high light exposure is kept more
than 10 seconds the device automatically will off. If you move the unit away from the bright light
after it shuts off the unit will turn back on. If short-term actuation of a sight in a highlight condition(for
check of serviceability)is necessary the sensor should be closed by a cover.
NOTE:
The automatic highlight protective system and automatic brightness control system do not
protect a sight from damage by bright light sources (a fire, headlights of the automobile, lanterns,
etc.). Do not point the device at a bright light source
.
