Medical Personnel (Operator, User)
This blood pressure recorder as well as the analysis program are
provided for the exclusive use of qualified physicians or trained
medical personnel under their direct supervision.
Patient, Caregiver (for use in home environment)
After thorough instruction from the attending physician, the patient or
his/her caregiver may use the device on their own (see chapter 4
Patient Information and chapter 10 Patient Diary).
1.2 Intended Use
The BR-102 plus / BR-102 plus PWA is a non-invasive ambulatory
blood pressure recorder. It uses auscultatoric and oscillometric
signals, or purely oscillometric signals to measure the blood
pressure of human beings. Systolic, diastolic, mean arterial
pressure and heart rate are measured. The BR-102 plus / BR-102
plus PWA is intended as an aid to diagnosis and treatment when
it is necessary to measure an adult or adolescent patient’s blood
pressure over an extended period of time (up to 24 48 hours).
Further, with each measurement, the PWA data will be saved for
subsequent external assessments.
The BR-102 plus / BR-102 plus PWA can be used for adults and
children (3 years old onwards) of both sexes and all ethnic origins.
This blood pressure recorder can be used on pregnant patients or
patients suffering from pre-eclampsia.
Patients with special needs such as children, the elderly, the
disabled, or people lacking the capacity for judgement must be
accompanied by a caregiver who will supervise the actions as well
as monitor the recording.

1.10 Operation with other Devices
Only use accessories and other parts recommended or supplied
by SCHILLER AG. The use of other than recommended or
supplied parts may result in injury, inaccurate information and/or
damage to the device.
Accessory equipment must be certified according to the respective

between the recorder and the PC and when possible, remove the
BR-102 plus from the patient before defibrillation.
The BR-102 plus / BR-102 plus PWA complies with EMC
regulations for medical products which afford protection against
emissions and immunity. However, the possibility exists that high
frequency disturbance from other devices can affect the recorder's
operation.

2Introduction
The SCHILLER BR-102 plus / BR-102 plus PWA is an Ambulatory
Blood Pressure Recorder used for single and long-term recordings.
The device can take up to 100 measurements over a 24 hour
recording period, and up to 200 measurements over a 48 hour
recording period. All recorded data is stored in an internal memory
and can be uploaded to the medilogDARWIN2 program. The recorder
has four recording programs that can be defined by the user with
individual time and interval settings for each program. This enables
long-term blood pressure measurements to be taken at pre-set
intervals for different patients and conditions.
Standard
• BR-102 plus Ambulatory Blood Pressure recorder Standard, or BR-
102 plus PWA (Pulse Wave Analysis)
• Four rechargeable AA NiMH batteries
• Battery charger unit
• Cuff size ‘M’ (medium) adult, and pressure hose with microphone
• Comfort Sleeve size ‘M’ (medium) adult
• Securing pouch with shoulder and waist-strap
• medilogDARWIN2 software
• USB cable
• BR-102 plus / BR-102 plus PWA user guide
Cuffs and Accessories
Cuffs are available in sizes ‘XS’ (extra small, Osc. only), ‘S’ (small), ‘M’
(medium), ‘L’ (large), and ‘XL’ (extra large). A list of these and other
accessories are given at the end of this book (see Accessories, page
63)

2.1 BR-102 plus / BR-102 plus PWA
The recorders are available as follows:
2.1.1 BR-102plus
The Standard BR-102 plus is identified by the black front casing.
There are two measurement methods available as follows:
• Option 1 employs the auscultatory (Riva-Rocci, Korotkoff) method
of measurement, with an oscillometric method as back-up. This
means that when a clear measurement cannot be obtained with the
auscultatory method, the oscillometric value is used. If a clear
measurement cannot be obtained with either method the BP meas-
urement is retaken. It is not possible to define oscillometric as the
primary measurement method.
• Option 2 employs the oscillometric method only. Note that with this
recorder no microphone is provided with the cuff.
2.1.2 BR-102 plus PWA
The BR-102 plus PWA (Pulse Wave Analysis) is identified by the
white front casing and takes measurements using the auscultatory
(Riva-Rocci, Korotkoff) method with oscillometric as back-up.
The setup and settings of the BR-102 plus PWA, measurement
interval, cuff application, and start and stop procedure are all identical
to the standard unit.
To obtain the extra data needed for PWA, the measurement cycle
differs from standard BP measurement. After every individual
measurement (and the SYS and DIA values recorded), the cuff is
again inflated to the diastolic pressure. This pressure is then held for
10 seconds while the PWA data is obtained. After 10 seconds the cuff
is again deflated and ready for the next programmed measurement.
An outline of PWA principal is given at the end of this book (see BR-
102 plus PWA, page 65).

2.2 The medilog®DARWIN2 Program
The medilogDARWIN2 program supplied with the recorder is used to
display, save, edit, analyse and print recordings. In addition to blood
pressure recordings, the medilogDARWIN2 can upload and view
Holter ECG recordings and SpO2recordings. Details of the program
are given in the medilogDARWIN2 user guide (see Documentation,
page 63).
2.3 Inserting/Changing the Batteries
1. Open the battery compartment by pressing and sliding the battery
cover away from the recorder.
2. Use the battery removal ribbon to remove the two batteries.
3. Insert two fully charged batteries.
– Ensure that the battery removal ribbon is positioned under the
batteries so that the batteries can be removed from the recorder
when depleted.
– Ensure that the batteries are inserted with the correct polarity as
shown.
4. Position the battery cover in the cover slides and slide back in
place until it clicks to secure.
Use NiMH rechargeable batteries supplied or recommended by
SCHILLER. Full capacity of new NIMH batteries are only reached
after three charge/discharge cycles.
Eneloop Pro NiMH rechargeable batteries (Panasonic 2450 mA)
or Energizer Ultimate Lithium batteries (ENERGIZER L91-FR6)
can also be used.
Do not mix batteries. Only use two batteries of the same type.
Do not use any other type of battery. The capacity of other
battery types may not be sufficient for a 24-hour recording and the
battery capacity symbol may be incorrect.

2.4 Connecting the Pressure Hose and
Microphone
Two hoses are compatible with the BR-102 plus: see Cuff and Cuff
Accessories, page 64.
• The battery capacity indicator is detailed in the operating section
(see Battery Status for NiMH Rechargeable Batteries, page 20).
• Battery charging details, disposal, and safety relevant precautions
are detailed in the maintenance section (see Battery Maintenance,
page 54).
• Battery and battery charger part numbers are detailed at the end of
this book (see Accessories, page 63).
The hose / microphone assembly can only be inserted in one
direction. Take care when positioning the assembly not to damage
any connectors. Do not pull directly on the hose or microphone cable.
Position the pressure hose connector (a) and attach to the BR-102
plus / BR-102 plus PWA by gently pressing until the connector clicks
in place. If the version is with a microphone (c), the plug is combined
with the hose and the assembly is inserted into BR-102 plus / BR-102
plus PWA at the same time.
Removing the Pressure Hose
Gently press the securing catch (b) to release and remove the hose
connector (and microphone jack plug) from the BR-102 plus / BR-102
plus PWA.

2.5.4 Battery Status for NiMH Rechargeable Batteries
The battery status display is a guide to battery capacity when using
NiMH rechargeable batteries supplied or recommended by
SCHILLER. If Energizer Ultimate Lithium Batteries are used, a
different battery symbol is displayed (see next page).
Battery Condition
Batteries deteriorate over time and must be replaced. An indication of
battery condition is given when batteries are first placed in the
recorder after a full charge, as follows:
The battery symbol in the upper right of the screen, indicates the
battery status. When the battery is full, the symbol is filled and gives
an indication of current battery capacity as it reduces during the
recording. The empty symbol indicates that the capacity is limited and
that the batteries should be changed. If the batteries are not changed
during this period, a warning message is given that the batteries must
be changed. If the batteries are still not changed an error message is
displayed before the recorder switches off (see next page).
