Storage of the doseBadge
The doseBadge should be stored in a fully charged state. If the doseBadge is
not used for 1 hour, it will shutdown and go into sleep mode.
To wake the doseBadge from the Sleep mode, shake the doseBadge until the
indicator light shows. Refer to “Shake-to-Wake” function on Page 18 for detailed
information about this function.
The “Shake to Wake” function has been added to the doseBadge to ensure that a
doseBadge that is not in use powers down to the minimum possible power
consumption.
The doseBadge should be kept on the charger unit when not in use to ensure optimum
performance. The doseBadge should be charged at least every 14 days to maintain this
optimum performance.
Battery Operating Life
The doseBadge system should be returned to Cirrus Research plc for
calibration and servicing. During this calibration and service, the performance
of the internal battery will be verified.
Installing the doseBadge Software
The doseBadge system is supplied with the dBLink3 software package.
dBLink3 is a program that allows measurements to be downloaded from the RC:112A
Reader unit to a PC. The dBLink3 software automatically recognises an RC:112A Reader
unit and allows measurements to be downloaded.
dBLink3 and the doseBadge Database are supplied on a CD-ROM and require a
PC running Microsoft 98SE or later. Install the software before connecting the
doseBadge Reader Unit to the PC.
To install the software:
1. Insert the Disc in the CD-ROM drive
2. Follow the instructions on the screen
If the installation program does not automatically start, run d:\setup.exe program from

Section 1 Introduction
Thank you for purchasing the doseBadge Personal Noise Dosimeter System from Cirrus
Research plc.
This manual describes the operation of the CR:112A and CR:112AIS doseBadge units
and RC:112A doseBadge Reader.
The measurements provided by these two versions of the doseBadge are identical. The
only difference between the units is that CR:112AIS version carries an MSHA Intrinsic
Safety Certification.
The doseBadge is a unique solution to the problems associated with the measurement
of Personal Noise Exposure. The doseBadge itself has no controls or cables which
means that the unit can be used in situations where the wearer is working in confined
spaces or where there is a risk of a cable being caught in machinery.
Measurements are downloaded from the doseBadge to a Reader unit via an infra-red
link which removes the need for keys or controls on the instrument.
The CR:112A & CR:112AIS doseBadge and RC:112A Reader Unit, when used with the
dBLink3 software, provide Dual Threshold Measurements.
The configuration of the two channels is as follows:

A system can be started with a single doseBadge and a Reader unit, and expanded by
purchasing additional doseBadges and the appropriate number of charging units. A
range of additional external charging units allow a system to be expanded simply and
easily without any of the components becoming obsolete.
Also described are the optional RC:101A Keyfob Remote Control and the UA:100
Windshield. The Keyfob allows the doseBadge to be started and stopped without the
RC:112A unit, and should be ordered separately.

CR:112A & CR:112AIS doseBadge User Manual
Page 8
How the doseBadge works
The doseBadge is controlled by the Reader unit through an infrared link. The link
between the doseBadge and the Reader is used to send information in a similar way to
a television remote control.
The RC:101A Keyfob also provides a method to start and stop the doseBadge without
using the Reader unit.
Each doseBadge contains a rechargeable battery which powers the unit throughout the
measurement period. Each charge of the battery is designed for one measurement.
The battery contains sufficient power to carry out a single measurement for over 20
hours although the doseBadge will run for much longer provided the battery is fully
charged.

Charging the doseBadges
Please note that this manual refers to the CU:110A Charger Unit only. The
information given does not apply to any previous version of the CU Charger
Units. The CU:110A is identified by a Black Case with the older charger units
having a White Case.
The CU:110A Charger Unit has a maximum charge time of 2½ hours. If the doseBadge
is not fully discharged, the charge time will be shorter than this.
It is essential that this procedure is carefully followed otherwise damage will occur to
the doseBadge battery.
Before using the doseBadges for the first time, ensure that the units are allowed to
charge fully. The doseBadges should be regularly recharged to maintain the
performance of the battery pack (inside the doseBadge)
For further information regarding the charging and maintenance of the doseBadge,
please refer to Page 38 “Maintenance & Care”
Connect the Charger to the mains power supply and switch on the power supply.

on a CU Series Charger unit.

CR:112A & CR:112AIS doseBadge User Manual
Page 14
Do not over tighten the doseBadge onto the Charger. The doseBadge should be
screwed onto the charger until the indicator change status and then one more half turn.
During the charge cycle, the green indicator will flash to show that the charging is in
progress.
Once charging has finished, the green indicator stops flashing and remains on
continuously.
At this time the doseBadge is receiving a trickle charge to keep it topped up. To ensure
optimum operation, the doseBadge may be left on trickle charge when not in use.
Summary of Charger Indicators
No Indicator doseBadge Not Connected
Green LED Flashing doseBadge Charging
Green LED On doseBadge Charged
The CU:110A doseBadge Charger will display errors during charging if, for example, the
doseBadge battery does not charge as expected. In this case, the Green LED will flash
quickly to indicate the charging error.
Removing the power from the CU:110A Charger
If the power is removed from the CU:110A Charger Unit and then reconnected, the
charging cycle will restart.
However, if the batteries in the doseBadges still contain charge when this occurs, the
charging time will be shorter than the maximum 2½ hours charge time.

CR:112A & CR:112AIS doseBadge User Manual
Page 15
Inserting the RC:112A Reader Batteries
The RC:112A Reader unit requires batteries to operate. The doseBadge contains a
rechargeable battery pack which is not user replaceable.
The batteries for the RC:112A Reader unit are located under the black cover on the
back of the instrument.
Before changing the main batteries, ensure that the Reader is switched off. The
memory and clock of the Reader unit are protected when the main batteries are
removed from the instrument.
The memory of the instrument is protected and the clock is kept for a maximum of 10
minutes.
Locate the battery compartment cover and remove it from the instrument. Remove the
batteries from the Reader unit and replace with batteries of equivalent type and quality.
The battery should be of alkaline type AA (LR6 / AM3 / MN1500 / Mignon).

For details of the procedure to set the clock, refer to section 4 ΑConfiguration &
Options≅. This is the default configuration and can be changed in the dBLink3
software.
Time History Measurement
The Reader unit can be configured to download Time
History data from the doseBadge at the end of the
measurement.
The current setting for the Time History download is shown
at the bottom of the screen. If the setting is not as
required, the setting can be changed.
For details of the procedure to change the Time History storage function, refer to
section 4 ΑConfiguration & Options≅.
Dose Exceedence
The CR:112A doseBadge can indicate when the 100% Noise Dose value has been
exceeded during the measurement.
When this option is switched on, the LED indicator on the
doseBadge will flash twice every second to indicate that
the noise exposure has exceeded the 100% Dose value.
As the % Dose value is a cumulative value, once the
indicator has started to flash more quickly it will continue
to do so for the remaining measurement duration.

CR:112A & CR:112AIS doseBadge User Manual
Page 18
“Shake to Wake” function
A feature of the doseBadge is the “Shake to Wake” function. Please read the
information below carefully before using the doseBadge.
In the doseBadge, a function has been added to lengthen the battery life of
the unit. If the doseBadge has not been used for 1 hour and it is not measuring data, it
will go into Sleep mode. This reduces the amount of power required to run the
doseBadge and a fully charged unit will remain charged and ready for use for up to 28
days.
If the doseBadge is in Sleep mode, it will not communicate with the Reader Unit until it
has been woken by physically shaking the doseBadge.
To check if the doseBadge is in Sleep mode point the Reader Unit at the doseBadge and
press the Stop button. If the status indicator flashes (blue), the doseBadge is awake
and can be used.
If the doseBadge does not respond, it is in Sleep mode and must be woken before use.
The doseBadge has an internal sensor that must be activated to wake the doseBadge
from Sleep mode.

CR:112A & CR:112AIS doseBadge User Manual
Page 19
To wake the doseBadge, shake the unit as shown in the diagram below. When the
sensor is activated, the doseBadge status indicator will flash (blue) twice and the
doseBadge can be used.
Note that the sensor may be activated when the doseBadge is removed from the
charger unit or when it is handled. If the indicator light does not flash when the
doseBadge is shaken, check that the doseBadge is not already awake by pointing the
Reader Unit at the doseBadge and pressing the Stop button.
If the indicator shows, the doseBadge is awake and ready to use.
Please note that if the doseBadge is running, it will not go into Sleep mode.
The doseBadge will only enter Sleep mode if it has been stopped for more
than 1 hour and does not receive commands from the Reader unit.
Please note that if the internal battery in the doseBadge is not charged, it will
not be possible to wake the doseBadge from Sleep mode. Ensure that the
doseBadge is fully charged before attempting to use the unit.
Insert the doseBadge in the Acoustic Calibrator
Before the doseBadge can be reset or calibrated, it must be inserted into the Acoustic
Calibrator cavity to allow communication between the doseBadge and the Reader unit.
The figures here show the alignment of the doseBadge in the Reader cavity. Ensure that
the InfraRed window of the doseBadge is aligned with the InfraRed Port of the Reader
unit.

CR:112A & CR:112AIS doseBadge User Manual
Page 20
The doseBadge must be pushed firmly into the calibrator cavity to make sure that there
is a good quality seal around the microphone. If the doseBadge is not pushed into the
calibrator cavity, the acoustic calibration level will be reduced and the calibration will
fail.
Resetting the doseBadge
The doseBadge must be reset before a measurement is made. Resetting the
doseBadge will clear any information from the doseBadge, program the
doseBadge with the user configuration, set the date and time and prepare the
unit for calibration.
The Reader will communicate
with the doseBadge and when
the Reset is complete, the
