Your new digital blood pressure monitor uses the oscillometric method
of blood pressure measurement. This means the monitor detects your
blood’s movement through your brachial artery and converts the
movements into a digital reading. An oscillometric monitor does not
need a stethoscope so the monitor is simple to use.
The HEM 431CAN comes with the following components:
• Monitor • Standard Cuff (9'' 13'' arm circumference)
• Inflation Bulb
• Instruction Manual in English and French
The HEM 431CAN Manual Inflation Blood Pressure Monitor is
intended for home use.
SAVE THESE INSTRUCTIONS

To assure the correct use of the product basic safety measures should
always be followed including the precautions listed below:
Read all information in the instruction book and any other literature
included in the box before using the unit.
Contact your physician for specific information about your blood
pressure. Follow the instructions of your healthcare provider.
Operate the unit only as intended. Do not use for any other purpose.
The unit is intended for use in measuring blood pressure and pulse
rate in adult patient population. Do not use on infants.
Do not use a cellular phone near the unit. It may result in operational
failure.
Changes or modifications not approved by the manufacturer will void
the user warranty. Do not disassemble or attempt to repair the unit or
components.
IMPORTANT SAFETY NOTES
4

BEFORE TAKING A MEASUREMENT
5
To ensure a reliable reading follow these recommendations:
1. Avoid eating, drinking alcohol, smoking, exercising, and bathing for
30 minutes before taking a measurement. Rest for at least 15 minutes
before taking the measurement.
2. Stress raises blood pressure. Avoid taking measurements during
stressful times.
3. Measurements should be taken in a quiet place.
4. Remove tight fitting clothing from your left arm.
5. Sit in a chair with your feet flat on the floor. Rest your left arm on a
table so that the cuff is at the same level as your heart.
6. Remain still and do not talk during the measurement.
7. Keep a record of your blood pressure and pulse readings for your
physician. A single measurement does not provide an accurate
indication of your true blood pressure. You need to take and record
several readings over a period of time. Try to measure your blood
pressure at the same time each day for consistency.
8. Wait 2 3 minutes between measurements. The wait time allows the
arteries to return to the condition prior to taking the blood pressure
measurement. You may need to increase the wait time depending on
your individual physiological characteristics.

BATTERY INSTALLATION
1. Press the ▲indicator on the
battery cover and slide the cover
off in the direction of the arrow.
2. Install 4 “AAA” size batteries so
the + (positive) and (negative)
polarities match the polarities of
the battery compartment as indicated.
3. Replace the battery cover.
BATTERY REPLACEMENT
Low Battery Indicator
When the Low Battery Symbol appears on the display screen remove
all the batteries. Replace with four new batteries at the same time.
When the Low Battery Symbol blinks a brief period of usage remains.
Long life alkaline batteries are recommended.
NOTES:
• Measurement values stored in the memory will not be deleted
during battery replacement.
• After replacing the batteries, reset the date and time.
Refer to page 9, Setting the Date and Time.
• Dispose of batteries according to applicable local regulations.

Set the monitor to the current date and time before taking a measurement
for the first time. If the correct date and time is not set, the measurement
values stored in the memory and the average value will not be correct.
The Blood Pressure Monitor automatically stores up to 30
measurement values. The monitor also calculates an average reading
based on the three most recent measurements taken within 10 minutes
of the last reading.
NOTES:
• If only two readings are stored in the memory for the 10 minute
period, the average is based on the two readings.
• If one reading is stored in the memory for the 10 minute period,
this reading is displayed as the average.

1. Connect the air tube of the arm cuff and the inflation bulb to
their air jacks.
2. Remove tight fitting clothing from your upper arm.
3. Sit in a chair with your feet flat on the floor. Place your arm on a
table so the cuff is level with your heart.

APPLYING THE ARM CUFF
4. Apply the cuff to your left upper arm so the blue arrow is centered
on the inside of your arm and aligned with your middle finger.
The air tube runs down the inside of your arm. The bottom of the
cuff should be approximately 1/2" above your elbow.
5. Wrap the cuff firmly in place around your arm using the closure strip.
APPLYING THE CUFF ON THE RIGHT ARM
Apply the cuff to your right upper arm so the blue arrow and the air
tube runs along the inside of your arm. The bottom of your cuff should
be approximately 1/2" above your elbow.
NOTE: Be careful not to rest your arm on the air tube.
This will restrict the flow of air to the cuff.

USING THE MEMORY FUNCTION
16
Every time you complete a measurement the monitor stores the blood
pressure and pulse rate in the memory. The Blood Pressure Monitor
automatically stores up to 30 measurement values. When 30 sets of
measurement values are stored in the memory, the oldest record is
deleted to save the most recent measurement values.
AVERAGING FUNCTION
The monitor also calculates an average reading based on the values of
the three most recent measurements that were taken within 10 minutes
of the most recent reading.
NOTES:
• If only two readings are stored in the memory for the 10 minute
period, the average is based on the two readings.
• If one reading is stored in the memory for the 10 minute period,
this reading is displayed as the average.
If the date and time is not set, the measurement values and the average
value will not be stored in the memory correctly.
TO DISPLAY THE AVERAGE VALUE
Average Value Symbol
1. Press the ON/OFF button to turn the power on.
2. Press the MEMORY button.
