When the vibra-call is off the icon is lacking; « »- 11. Icon of a bell: the bell is on.
Operating mode There are there three operating modes in the unit: «MONITORING», «BACKGROUND» and «MENU». The «MONITORING» mode is set automatically at start of units functioning. This mode gives estimation of a dose rate and indications output to the LCD. The button «CURSOR» in a «MONITORING» mode (page 8), fulfill the function of turning on/off a backlight of display. A short-term click on it switches on a backlight for 2 s It allows seeing indications in a twilight or darkness.
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.
Menu mode In «MENU» mode one can alter unit measures, arrange a magnitude of a threshold signal, turn on/off alarm and a vibracall, enable a «BACKGROUND» mode and also receive reference information. Switch to a «MENU» mode ceases monitoring of a radiation dose rate. In order to switch from «OBSERVATION» mode to a «MENU» mode press and release a «MENU» button (page 8). A main menu displays on the screen. At start the icon « » is always situated on the upper line of the menu, like in case of «UNIT» section.
Units Unit measures are set in this section. They could be either µSv/h or µRem/h. Switch from a «MONITORING» mode to a «MENU» mode (page 15) in order to alter unit measures. Press the «SELECT» button. Screen 2 will appear. 1 2 3 4 5 6 Press « » button and a cursor « » moves one line down to µRem/h unit measure (screen 3). Press a «CHANGE» button and an « » icon is set opposite to a selected unit measure (screen 4). Press a «RETURN» button to return to the main menu screen.
Levels Exceeding of a threshold dose rate which can be set in «LEVELS» section provokes to alarm signal actuation. A threshold signal is made for situations when alarm or vibra signals are needed only in case of a fixed radiation dose rate exceeding. User himself sets a value of a threshold signal (range from 0,10 up to 0,90 µSv/h and discreteness of 0,1 µSv/h). Choosing a type of a signal (audio or vibra signal) is carried out in a «SETUP» section (page 26).
Example of changing the level of a threshold signal from 0,30 µSv/h to 0,40 µSv/h is shown below. To change a level of a threshold switch from «MONITORING» to «MENU» mode (page 15). The main menu is displayed on the screen.
Press a « » button and the cursor « » moves to«LEVELS" section (screen 2). Press a «SELECT» button and the screen 3 will appear. A double-click on a « » button (screens 4 and 5) moves the cursor « » to « 0,30 µSv/h ». Press a «CHANGE» button and the icon « » will be placed opposite to « 0,30 µSv/h », and a digit 3 becomes underlined (screen 6); Press shortly four times a « » button and a required value of « 0,40 µSv/h » will be set (screens 7, 8, 9 and 10).
Background «BACKGROUND» mode can be turned on in this section. An average value of a background dose rate can be easily calculated with an algorithm approximate to methodical instructions of State Sanitary Epidemic Inspectors in Ministry of Health of The Russian Federation. МУ 2.6.1.715-98 «Conducting a radiationally-hygienic inspection of inhabited and public buildings» To actuation of a «BACKGROUND» mode switch from a "MONITORING» mode to a «MENU» mode (page 15). A main menu displays (screen 1).

Setup Two types of signal can be chosen in the «SETUP» section: «AUDIO» and «VIBRA-CALL» which can be turnd on/off by setting an icon « »opposite to a correspondent choice. Example of activating a vibra signal instead of an audio one is demonstrated below. To activate a vibra signal switch from the «MONITORING» mode to the «MENU» mode (page 15). Press « » button 3 times, the cursor « » will be displaced opposite to the «SETUP» section (screen 1). Press «SELECT» button, the screen 2 will appear.
1 2 3 4 5 6 7 From this moment a vibra signal turns on if the value of a dose rate exceeds the installed threshold of alert (of course only if a threshold is not turned off, page 17). A vibra signal works (in a pulse-mode) periodically till the end of an observation cycle. This algorithm is repeated in other subsequent cycles. A vibra signal is the effective method for alarming the user about the excess of the installed dose rate threshold.
In the «MONITORING» mode the installed setting are revealed with icons on the main screen «RD1503+ »: « » - audio signal is on, « » - vibra call is on. When audio and/or vibra signals are off bell the icons are lacking. Note: 1.A sound signal is usually used in noisy premises or on the street. 2. In quiet places such as offices and flats we recommend to use a vibra call or a sound alarm with a threshold installed.
Service In the «SERVICE» section the following is mentioned: telephone number of an organization where a radiation monitor RADEX RD1503+ can be acquired, telephone number of the QUARTA-RAD Ltd. Company, which sell wholesale a radiation monitor RADEX RD1503+; internet address www.quarta-rad.ru, where you can read news about a radioactive situation in Russia, get acquainted with radioactivity safety norms and other normative documents; Place a pointer « » opposite to «SERVICE» with the «CURSOR» button.
Background mode This mode is made for examining inside the buildings. In the «BACKGROUND» mode the estimation of the radiation dose rate is similar to one in the «MONITORING» mode (page 14), yet the display gives not just one but two indications. One stands for the difference of a dose rate between the average indication and background, the second is for a background dose rate.
Switch from the «BACKGROUND» to the « M O N I TO R I N G » m o d e s i s c a r r i e d o u t i n t h e «BACKGROUND» section in menu (page 20) by placing « » icon opposite to «OFF». The rules and sequence of defining the average value of a background dose rate are covered in section «Radiation control in quarters and public buildings»(page 37).
Preparations for using Before actuating the device read the operation manual and functions of operating controls carefully (page 8). Installation of power elements 1.Take off the cover of battery compartment; 2.Install into the battery compartment one or two power elements size «AAA» abiding polarity of contacts. 3.Install the cover of battery compartment. When conducting a long-term examination we recommend to install two power elements, for a short-term just one for it's possible to use one power element.
The estimation output exceeding the natural background that is ordinary for the given location is the evidence of the radioactive impurity of the inspected object. The«BACKGROUND» mode is presented for convenience of defining such objects (page 30). Detecting the location of an ionizing radiation source it is necessary to move a working device above the surface of examined object, being oriented on frequency increase of a sound signal (in menu settings: levels - off, audio - on).
Device using Switching on the device To switch on the device press the «OFF» button (page 8) and the screen «RD1503+» will be displayed. The sequence of survey After switching on the device the examination of the radioactive environment starts. During the time of observations each registered quantum of radiation is accompanied by a displayed presentation of the icon« » (page 10) and a short audible signal, if the sound is switched on and the threshold is off.
* The short cycle of observation is equal to 10 s and made for prompting the deriving of preliminary results. The first reliable result is displayed after 40 seconds of observation and designated by the icon « ». The icon « » in the form of side of a square designates the number of executed observations: - equal to four observations). - equal to two observations); - equal to three observations); - equal to four observations).
The device analyzes a diversion of current value regarding a result of the previous observation and averages it. If the difference exceeds a defined value, the current result is displayed instead of the average one. For example, as results of three observations the average result is 0,20 µSv/h, and the current value 0,80 µSv/h is registered in the fourth cycle, than the result of the fourth observation will not be averaged and we shall see 0,80 µSv/h and the icon « ».
Radiation control in quarters and public buildings According to «Norms of radiation standards (НРБ-99) » the defensive measures in inhabitant buildings should be conducted if a dose rate of a gamma radiation inside the building exceeds a dose rate outside for more than 0,2 µSv/h.
