«Grad A-1000 Pro» can operate in an absolutely silent mode, has a large protection range, flexible customizing and wide functionality.

If pests have already occupied your household’s territory, only several weeks or even days will be enough to clear the territory from «intruders». Ultrasonic repeller makes it impossible for pests to continue staying in the protected area, but it is absolutely harmless to humans and pets (except hamsters, pet rats and so on).

The device doesn’t contain chemicals and can be applicable to:
• production facilities (plants, factories, warehouses, bakeries, cafes, restaurants, cattle ranches, chicken farms)
• household compartments (stand-alone houses, cottages, cold cellars)
• granaries, vegetable stores, food stores.

Advantages of «Grad A-1000 Pro»:
1.  Extremely large protection range - up to 1000 square meters (10,800 square feet).
Such an astounding range became possible by virtue of increasing power of transducer and upgraded algorithm of ultrasonic radiation.
2. Triple effect. The device can affect pests by 3 repelling techniques simultaneously: ultrasound, audible sound and bright strobe. Such synergetic effect multiplies the effectiveness of protection.
3. Silent operation. «Grad A-1000 Pro plus» has a separate mode in which the repeller produces no audible sounds! This has to do with the fact that in this mode the repeller only uses ultrasound which is not perceived by human beings.
4. The effectiveness of the device doesn’t decrease with time because pests cannot adapt to non-repeating sequence of ultrasound.
Laboratory experiments on pests show that prolonged exposure to unaltered frequency gradually loses effect on pests and they stop perceiving it as a signal to escape. However, «Grad A-1000 Pro plus» uses unique nonrepeating sequence of ultrasound which has no addictive effect for mice and rats. Hence the device will protect your territory for many years.
It works without "blind spots" and doesn't reduce effectiveness in zones where pests can hide.
5. 4 modes of operation: 2 modes to repel mice and rats, a mode to repel mosquitos and a mode to repel other insects (fleas, spiders, mites, moths). Such versatility makes «Grad A-1000 Pro plus» the most effective protection device for your household. 
6. Ultrasonic emitting power adjustment. This option allows choosing the right level of emitting according to the size of protected compartment.
Number of emission power control levels:
• Level 1 – 25%
• Level 2 – 50%
• Level 3 – 75%
• Level 4 – 100%

Functional modes:
• mode 1 - most effective mode for expelling rodents (sound and ultrasonic waves)
• mode 2 - ultrasonic (silent) expelling mode for rodents and bats
• mode 3 - expelling mode for mosquitos
• mode 4 - expelling mode for other insects (fleas, spiders, mites, moths).
Note: mode 3 is ineffective for expelling mosquitos outdoors, the device should be placed in the window opening. In this case the number of mosquitoes that enter the room will be significantly reduced.

The repeller «Grad A-1000 Pro» requires no special pre-operation adjustments or settings. It is very simple in use. Maintenance requires only cleaning the surface of the device.
The device should be installed in the center of compartment at a height of 60-70 centimeters (23,6 - 27,5 inches) from the floor. Also the device can be placed on a wall.
