How to conduct the examination correctly. At an examination of the radiological situation it is necessary to remember, that the ionizing radiation has static random character, therefore the indications of the monitor in identical conditions will not remain strict stationary values. For more precise definition of a power level of a dose it is necessary to conduct from 3 up to 5 cycles of inventory, not turning off the device.
On the front side of the monitor there are marked: trade mark of the manufacturing plant; trade mark – RADEX. Conventional designation of the monitor - RD1503 appears on display at its turning on. The assembly number of the device is in the main menu.
Transportation and keeping custody. The device in the package of the manufacturer may be transported by any mode of transport on any distance.
