Safety Precautions

Read the safety instructions carefully before using the device.
Follow the applicable safety instructions listed below. Heed all
warning.

• Do not leave the device for a long time under the
impact of a direct solar light or height temperature, for
example on an instrument board or in a trunk. The
impact of the sunlight or temperature can lead to
electrolyte leakage from power supply, their
overheating or explosion and therefore to arson, burn
and other injuries. High temperature can also cause
malformation of the device’s frame.

• Do not leave the device in damp and dusty
places. It can cause arson, electrical shock and other
damages.

• Protect the unit from shocks and heavy
mechanical stress that can cause damages of the
device.

• The unit is an accurate device. Avoid its fall and
other mechanical stresses.

• The body of the device is not waterproof;
therefore it can’t be exposed to raining or water. If the
device comes in touch with water, it is necessary to
switch it off and apply to QUARTA-RAD Ltd. In case a
small amount of water gets on the device or salty air,
wipe it with a soft tissue, place it in a warm and dry
premise and wait until a complete dehumidification
from the interior of the unit.

• Keep the unit away from devices such as
electric or magnetic motors, which generate strong
magnetic fields. Do not use and put the monitor close
to areas where high electromagnetic signals are
generated, such as transmitting tower. Superhigh
frequencies can lead to malfunctioning.

5

Do not attempt yourself to dismantle or to fix the

device.

Do not place the unit in a microwave and do not carry

out any monitoring with ionizers and ozonizers turned on.

Do not let particles penetrate through a perforated

hole inside the unit.

Do not touch electrical links of a battery block. It can

cause corrosion of links and affect normal functioning.

Condensate can occur on internal parts of device in
case of a rapid temperature difference from higher to
lower level. To prevent it place the device inside a plastic
bag. Keep it there till its temperature reaches one of the
environment.

In order to prevent damages to the unit do not use it if a
condensate has appeared. In this case extract power
batteries from unit and wait for a while till a condensate
evaporates. It is possible to use the device only after a
complete vaporization of a condensate.

Extract power batteries if the device is not being used
for a long time and keep the unit in dry and cool
conditions.

It is not recommended to keep the unit in places like
labs where chemical agents potentially may cause
corrosion.

It is necessary to check working capacity of the unit
before usage if it was kept in stowage for a long time.

Precautionary measures for the LCD.

• LCD posses a high-precision technology.
Nevertheless one disabled pixel can be displayed
on LCD, in the form of a permanent black dot on it,
and it is not considered as a malfunction and does
not impact on the image.

• Do not hit and press on the LCD as it can cause
fractures and damages of the display.

• In case of LCD surface contamination switch
off the devise and wipe gingerly the LCD with a
soft tissue that does not scratch it.

• Do not leave the device for a long time under the
impact of direct solar and fluorescent light.

• Do not let deleterious chemical substances, such
as acids, alkali, and solvents etc. fall on the display
and do not keep it in places where these substances
are located.

• Response time of the LCD increases at low
temperatures and display can darken at high
temperatures. Standard features of display will
restore at room temperature.

Precautionary measures for the power supply.

• Keep power supplies out of reach of children. Its
chemical agents represent danger in case of
casual swallowing. In this case apply to a doctor
immediately.

• Do not hold a power supply with metallic tools such
as pliers for it can cause a short circuit.

• Do not heat or dismantle a power supply for it can
stop functioning.

Monitoring mode

This mode gives a value of a dose rate displaying
indications on the LCD. Every registered quantum is displayed
on LCD as « » icon. Blinking frequency of « » icon is
proportional to the strength of a radiation dose rate.

A short cycle of observation is introduced in order to reduce
a waiting time of the first reading. The indications of a short
cycle and its icon of two parallel lines « » (page 10,
paragraph 4) are displayed within 10 s, but have a rough value
and are updated during the next three subsequent short
cycles. The readings of a short cycle are effective as initial
estimation of a radiation dose rate

Within 40 s after activation the device gives the first
indication which is presented on display as side of a square
« » and shows a number of performed observations.

These icons (page 10, paragraph 4) allow determining
visually the number of averaging cycles. They are extremely
useful for detection of a strong variation in a radiation dose
rate (for example in case of a local/domestic radioactive
contamination) as in such circumstances the icon « » will
be changed to « » and that it is quite easy to note. At the
same time the estimation of a dose rate starts all over again
from the first cycle, so averaging indication of the previous
cycles are not taking into account.
