2 BEFORE YOU BEGIN
Thank you for purchasing a Polimaster Personal Combined Radiation Detector/ Dosimeter РМ1703МО-
1. Before operating this unit, please review this guide thoroughly and retain it for future reference.
The Personal Combined Radiation Detector/Dosimeter is designed to detect, search, and locate gammaemitting radioactive sources. The detector is easily handled requiring only understanding of the basic
parameters and settings for proper operation.
The device is intended for everyday or emergency use by firefighters, military, police, etc. It is designed
for use in any area where radiation dose and dose rate are required to be measured, where exceeding the
default dose and dose rate values requires an alarm. In addition, the device provides accumulated
information about the accumulated dose and system analysis of the gathered dosimetric information.
3 PRECAUTIONS
1. Keep the instrument at least 4 inches from radio emitting sources, such as cell phones, to avoid
false positives.
2. Avoid severe mechanical shocks and submerging the device into water.
4 GENERAL DESCRIPTION
The РМ1703МО-1 belongs to Polimaster’s new generation of highly sensitive, small and power-saving
personal gamma combined radiation detectors/dosimeters. When ON the detector continuously monitors
the environment for radiation and alerts the user with a visual, audio and/or vibrating alarm if a radiation
source is detected or a radiation threshold is exceeded.
All operations history is stored in the device’s permanent memory, protecting the data even when the
battery is removed. The stored data can also be transferred from the РМ1703МО-1 to a personal
computer via its infrared interface.
The instrument is recommended for detecting and locating radiation sources in both indoor and outdoor
environments.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation
4.1 Display and Control Buttons
The instrument is equipped with two control buttons located on its top panel:
• MODE button — (switching on the instrument; switching between operation modes; background
level calibration; changing the device parameters in setup mode)
• LIGHT button — (switching on the backlight; enabling IR communications with a PC; changing the
parameters in setup mode.)

The LCD screen may display any of the following information:
• gamma Dose Rate (DER) in µR/h;
• Dose (DЕ) in µR;
• n coefficient: number of mean square deviations for the gamma threshold (also called “alarm
multiplier”);
• Messages "tSt", "CAL", "OL", "oFF" etc.;
• “ ” sound alarm icon (if sound alarm is enabled);
• “ ” vibration alarm icon (if vibration alarm is enabled);
• Blinking “h” symbol — indicates that there has been an alarm actuation and information about it
hasn’t been uploaded to a computer;
• Blinking “S” symbol – indicates that the search mode is currently on;
• Critical battery discharge: displayed when the battery voltage drops below 1.15 V.
An analog bar in the lower area of the LCD display indicates the time left until self-tests or background
calibration are completed.
In the Search Mode, Measurement mode and Dose indication mode, the analog scale segments represent
the dynamics of radiation environment change. The bar represents a relative excess of the measured
value over the set alarm threshold.
For additional information, please contact Berkeley Nucleonics or Polimaster directly. 800-234-7858
