5.3 Operation at night
You can use the device with the head gear or without it.
When used with the head gear, first adjust all the straps for
individual head size. Take off the lens covers (6) from the lens
(7). Turn on the device-using switch (1). In case of insufficient
lighting when observing an object, which is situated not far from
the viewer, turn on the I/R illuminator by turning the I/R switch
(1). The red indicator (Fig. 3) will be on.
Note: The I/R illuminator is visible to anybody with a night
vision device and will disclose the user’s presence.
You can raise the unit up for unobstructed vision without taking
the head gear off by using the “flip/flop” feature (Fig. 2). To
switch the unit into off-working position: press the lever (9)
down and raise the device into vertical position, until you hear a
click. The unit automatically shuts off in the upright position
(Note: this is an optional feature).
Reverse the operation for a working position.
After operation the user should turn off the unit by rotating switch (1)
to the OFF position. Put protective lens caps (6) on the lens (7). After
operation remove the batteries from the battery compartment to avoid
any damage of the device in case of occasional leakage of electrolyte
from the batteries.
