to a bright light. Please note that even though this is an
effective protection source, we at Luna Optics still strongly
recommend avoiding any such exposures to bright light,
especially prolonged ones in order to preserve the full life of the
tube. In addition to the gain control, you may choose to
activate the additional light protection sensor by rotating the
Menu Switch (8) to ALL or P position (PRO model only - see
MENU SWITCH information below) or on regular LN-EBG1 move
the provided rubber cover from covering the sensor. NOTE:
models with rangefinder and 5x lens have light sensor
positioned in a different location (on the same side as the IR
illuminator (14) on top of it)
MENU SWITCH (PRO model only!):
Your night vision goggles come
with special Menu Switch (8)
which allows you to select 4
different levels of operation:
The default selector level is L+P, which provides manual
operation without head-mask and relies on auto-gain
feature to protect the unit from excess light. It is
recommended to switch to this level when using the
device as hand-held binocular (not on the head-mask)
and at the nighttime when risk of bright light exposure is
limited.
Next level is L – it is used when goggles are mounted on
a head-mask and provides an automatic power
shutoff when goggles are flipped up and automatic
power on when goggles are flipped down. This level
can only be used while unit is mounted on the head-
mask – the unit will not turn on if the menu switch is at
this level while using the device as hand-held
binocular.
Next level is ALL and it is identical to level L except it
turns on the light protection sensor in addition to the
automatic gain control. This level is only useful when
mounted on the head-mask and a risk of bright light
exposure exists.
Last level is P, which turns on the light protection sensor
in addition to the gain control, providing extra level of
light protection especially in situations when you are
suddenly exposed to the excessive and dangerous
amounts of light. This feature immediately shuts off the
unit in such situations. It is recommended to switch to
