READ THIS FIRST
Thank you for purchasing this Polimaster®product. Before
operating the unit, please read this manual thoroughly and retain
it for future reference.
Radiation Detector PM1904 POLISMART®II is designed to
continuously monitor and measure ionizing radiation from gamma
emitting radiation sources and provide a visual alarm whenever
the preset thresholds are exceeded. Users do not need to be
experts in health physics to operate this instrument; however,
understanding of basic principles of ionizing radiation is desirable
for proper operation.
“Made for iPod®”, “Made for iPhone®”, and “Made for iPad®” mean
that an electronic accessory has been designed to be connected
specically to iPod®, iPhone, or iPad, respectively, and has been
certiedbythedevelopertomeetApple®performance standards.
Apple®is not responsible for the operation of this device or its
compliance with safety and regulatory standards. Please note that
the use of this accessory with iPod®, iPhone® or iPad®may affect
wireless performance.

PRECAUTIONS
•Keep your PM1904 charged at all times for proper exposure
measurement.
•Charge the instrument for at least 4 hours before the initial use.
•Please observe all local regulations and safety procedures when
working with sources of ionizing radiation.

GENERAL DESCRIPTION
Radiation Detector PM1904 POLISMART®II belongs to
Polimaster® new family of highly sensitive, small and efcient
gamma detection devices. When ON, the device continuously
measures the ambient Dose Equivalent Rate (DER) and the
ambient Dose Equivalent (DE) of gamma radiation and compares
those measurements to the preset thresholds. In case thresholds
are exceeded PM1904alertstheuserwithashinglightsignals
indicating that radiation source is nearby or critical dose has been
accumulated.
The operation history is stored in the instrument’s non-volatile
memory and may be downloaded to an iPhone®through its
connector. PM1904 can also exchange data with the iPhone®in
real-time, thus transferring actual DER and DE readings to the
iPhone®.
The instrument may be used both indoors and outdoors by various
users who need to track environmental gamma radiation and
personal exposure.

Instrument Design and Control

10
The instrument requires no control buttons and operates fully
autonomously when the battery is charged. It automatically
records all measurements in non-volatile memory at preset
intervals. There is one LED display that can indicate the following:
•Green light ashing every second – PM1904 is connected
to a PC or charger USB port, battery is charging;
•• Green light indicates the full charged battery;
••• Green light ashing every 10 seconds – the instrument is
operating normally and background radiation is below the
preset thresholds;
•Red light – indicates that DER or DE thresholds have been
exceeded. A single red ash every second means the DER
thresholdhasbeenexceeded;adoubleredasheverysecond
means the DE threshold has been exceeded;
•Orange light ashing every 5 seconds – partial battery
discharge. Please connect PM1904 to a USB port to charge
the battery.

11
OPERATION
The normal operation mode of PM1904 is always ON. This
provides continuous monitoring and correct measuring of the
Dose Equivalent of gamma radiation and provides accurate
readings and measuring of background radiation. When the
instrument is charged and operates normally, the green LED light
ashesevery10seconds.
If the light does not ash green, but instead ashes orange, the
battery is partially discharged. If there is no light indication on the
LED the battery is critically discharged. Please charge the battery
of PM1904 following the procedure described below.NOTE!
Before the rst use, please allow the battery to be fully charged in a
USB port for at least 4 hours.

Charging PM1904
To charge PM1904 please connect it to any USB port of a personal
computer or use a wall charger with a USB slot. When the battery
is charged, the Green light is always on.
A full charging cycle requires 4 hours. This will provide 2200 hours
of the instrument operation under normal background conditions.
The Manufacturer recommends charging PM1904 for 4 hours
every month, to ensure reliable operation of the instrument for at
least 1000 hours and to extend lifetime of the battery.
NOTE!
If the battery is partially discharged an orange LED light ashes every
5 seconds.
IMPORTANT!
After partial battery discharge indication appearing the instrument
keeps working for 16 hours. Using PM1904 in the environment with
radiation background higher than 0.1 mSv/h it is recommended to
charge fully PM1904 before operation.

13
Normal Operation Mode and Alarms
After PM1904 is charged and disconnected from the power source
itisreadyforautonomousoperation.Thegreenlightashesevery
10 seconds and the instrument continuously measures DER and
DE of gamma radiation and compares it to the preset thresholds.
If the thresholds are exceeded, PM1904 alerts the User with a red
LED indicator. If the DER threshold is exceeded the instrument
ashes the red LED light every second. If the DE threshold is
exceeded,theredLEDlightashestwiceeverysecond.
Manufacturer’s preset values are the following:
•DER Threshold 1: 1.0 µSv/h
•DER Threshold 2: 10 µSv/h
•DE Threshold 1: 10 mSv
•DE Threshold 2: 10 Sv
When the DER threshold is exceeded that usually means there is
a source of radiation nearby and the general course of action is to
leavethearea(theradiationratedropssignicantlyasthedistance
from the radiation source increases). The red DER alarm will stop

14
after background radiation drops below the preset threshold.
When the DE threshold is exceeded it doesn’t necessarily mean
that there is a radiation source nearby. Moreover, the red DE
alarm will not stop even if the current background radiation level
returns to its normal state. This usually means that the User has
beenintheincreasedradiationbackgroundeldfortoolongand
the risk of damaging effects to personal health is elevated. Please
consult health specialists in such circumstances or in case of any
uncertainty.
The red DE alarm can be reset only by connecting PM1904 to an
iPhone®and using the User Software.
IMPORTANT!
To set up suitable values for thresholds and/or to get instructions
for dealing with any given value of DER/DE the user should consult
authorized licensed specialists. The User assumes full responsibility
for compliance with applicable laws, regulations, and standards in
connection with the use of the device. Additionally, the User bears all
the risks in interpreting the device output and/or making decisions
based on the device operation(s) or reading(s).
To set new thresholds, and/or reset current DE value to zero,
connect PM1904 to an iPhone® and use the User Software.

15
Recording Data to Internal Memory
When operating normally, PM1904 records current DER and DE
values to the internal memory. The interval of recording can be
set within the values from 1 to 1000 minutes using the supplied
User Software. The Manufacturer’s preset value is 1 hour.
Alldata recorded intotheinstrument’s memory aretimestamped
with the internal instrument clock. When the instrument is
connectedtotheUserSoftwareovertheconnectorfortherst
time, it will prompt to synchronize the internal PM1904 clock
with the iPhone®. It is recommended to synchronize time with
the iPhone®every time data is downloaded from PM1904 into
the iPhone®. Otherwise the timestamps of the DE and DER
readings might not be correct.
IMPORTANT!
After complete battery discharge (no LED indication) the internal
instrument time as well as data recording stops. Thus after recharging
the instrument it is recommended to synchronize time with an
iPhone® in order to have proper timestamps of the DER and DE
readings in the instrument non-volatile memory.

16
COMMUNICATION WITH iPhone®
PM1904 POLISMART®II communicates with an iPhone®by using
iOS App available on the App Store.
It allows setting up User’s thresholds and data recording intervals,
synchronizing the internal instrument time, downloading event
data stored in the instrument memory to the database and
working with the instrument over the iPhone®in real-time data
exchange mode.
TROUBLESHOOTING
Most of the problems that have been analyzed can be traced to
low battery power, so troubleshooting in the eld is limited to
charging the battery regularly. This is especially important if you
are planning to stay in an environment with elevated radiation
background.
