Utilization of 2x Magnifier Lens, Components

Utilization of 2x Magnifier Lens

Your NVD-NORS210 (type equipped with the objective 64mmF/1.2) can be used with an optical 2x magnification lens in order to obtain doubled magnification. The lens (identified as 2x) doubles focal length of the objective. It is fixed on a

setting thread under the light filter of the objective (outer side of the objective). To take off a cover (12) from the body of the device (1). The 2x lens must be tightly fixed screwing it to the rest.

NOTES.

When 2x magnification lens is used in an active mode (with IR illuminator) partial darkening of the field of view will be observed, since the 2x lens has a large diameter of the objective. In order to avoid this effect (in case of simultaneous utilization of the device with IR illuminator and 2x lens) it is recommended to order the device with Z-like form of the illuminator.

When a 2x lens is ordered for the device with already implemented adaptation for a rifle, the opportunity of installment of 2x lens should be checked, since its diameter exceeds the diameter of the objective and equals 80mm.

Installation of Batteries

Your NVD-NORS210/220 works from two AA batteries. Be sure that the batteries are in good condition and they are installed in accordance with the picture on the battery compartment.

To replace the batteries it is necessary to turn off the unit, remove the cover of the battery compartment and replace old

batteries with new ones, keeping polarity of the batteries.

NOTE.

To ensure the longest operation time of the device and full power of the IR illuminator (using one set of batteries) it is recommended to use alkaline batteries. These batteries possess the most stable characteristics of a current consumption when their power capacity is reduced.

Testing of Operation in Daytime

In order to test operation of the device you can turn it on with the closed cover in daytime. Cover of the device has a hole small enough to test the operating condition of the device. When the device is turned on the observed picture appears on the screen in a yellow-green color.

NOTE.

The device won’t burn out even if you open the cover of the objective. When the light is excessively bright protection will be activated and the image will curtail. When the device is placed in a dark place the image will be restored in several seconds.

CAUTION.

The device is not supposed to be directed toward bright sources of light: bright lamps, the sun, welding and etc – it may result in the reduction of the coefficient of brightness magnification of the device. In order to avoid the fatigue of photo-
