6.3 Operation at Night

Take off the lens covers (7) from the lenses (6). Turn on the device by pushing and holding the “On” button (4). In case of insufficient lighting when observing an object which is situated not far from the viewer, turn on the infrared illuminator by pushing and holding the button (3). As soon as the “I/R On” button is released the infrared illuminator turns off.

Note: The illuminator will be activated only if the unit has been already switched on by the button (4).

Note: If you look directly at front of the binocular when infrared illuminator is on it appears as a red dot at a size of a lit cigarette. The illuminator can be also detected using night vision device. Therefore, if you need to remain undetected, use the illuminator with caution.

Note: The unit automatically turns off after few minutes. This feature can be used to economically utilize the batteries power by periodically switching on and off the device during operation.

If brightness of the screen decreases, replace the batteries. Put protective lens caps back on the lenses after operation. If you don’t intend to use the device during long time remove the batteries from the battery compartments to avoid any damage of the device in case of occasional leakage of electrolyte from the batteries.
