Detailed Description

The BPM65 Arm Type Blood Pressure Monitor detects pressure oscillations in the upper-arm cuff while it inflates. Its internal pressure sensor processes those oscillations to estimate systolic pressure, diastolic pressure, and pulse rate.

The main controls and connections are located on the monitor body:

• LCD display: Shows pressure values, pulse, date and time, memory information, battery status, alarm settings, temperature units, and indicators.
• M1 memory button: Recalls readings saved in memory bank 1 and is used to increase selected setup values.
• M2 memory button: Recalls readings saved in memory bank 2 and confirms setup selections.
• MODE button: Opens the date, time, ambient-temperature, and alarm-clock functions.
• POWER button: Starts or stops the monitor and can interrupt cuff inflation or deflation.
• Air socket: Receives the cuff-tube connector.
• Cuff connector and tube: Carry air between the monitor and the upper-arm cuff.
• Upper-arm cuff: Applies controlled pressure around the arm during measurement.

The display may show systolic pressure, diastolic pressure, pulse rate, a heartbeat symbol, an irregular-heartbeat symbol, the WHO range indicator, memory status, a low-battery symbol, date and time, alarm status, and the selected pressure units.

Safety

• Use this device only for adults. It is not suitable for pregnant, neonatal, or pre-eclamptic patients.
• Do not place the cuff over a wound, an arm with an intravascular access point, an arteriovenous shunt, or an arm receiving vascular treatment.
• Do not use the cuff on a person who has undergone a mastectomy unless a qualified healthcare professional provides appropriate guidance.
• Do not kink, compress, or restrict the cuff tube. Restricted airflow can interfere with circulation and measurement.
• A cuff inflated on one limb can temporarily affect monitoring equipment connected to the same limb. Check that circulation is not impaired for an extended period.
• Avoid taking measurements too frequently. Repeated cuff pressure can interfere with blood flow and cause discomfort or injury.
• Keep the monitor, cuff tube, and batteries away from children and pets. Cables can create an entanglement or strangulation hazard.
• Do not modify the equipment or use it in an ambulance, helicopter, or other environment outside the stated home-healthcare use.
• Temperature, humidity, altitude, movement, trembling, exercise, body position, measurement site, and physical condition can affect readings.
• Keep the monitor stable, remain still, and do not speak during measurement.
• Stop inflation or deflation at any time by pressing the POWER button if the procedure becomes uncomfortable.
• Keep the device away from strong electromagnetic sources. As a practical precaution, maintain distance from mobile phones and other radio transmitters during operation.
• Do not interpret individual readings as a diagnosis. Share unusual or repeatedly abnormal readings with a physician or trained healthcare professional.

Before Measuring

1. Choose a quiet location and sit in a relaxed position.
2. Avoid smoking, eating, alcohol, medication use, and physical activity for 30 minutes before measuring, unless medication timing is directed by a healthcare professional.
3. Rest quietly for at least 15 minutes before starting.
4. Remove tight clothing or jewelry that could interfere with the cuff.
5. Use the same arm and a similar time each day when tracking changes. Blood pressure can differ between arms.
6. Wait at least 15 minutes between readings. Individual recovery time may vary.
7. Record blood pressure and pulse results so they can be reviewed with a healthcare professional.

Setup and Operation

Install or Replace the Batteries

1. Press the latch and lift the battery-cover panel on the bottom of the monitor.
2. Insert four new 1.5 V AA alkaline batteries. Match each battery to the polarity markings inside the compartment.
3. Close the battery cover securely.

Replace all batteries when the low-battery symbol appears or when the display does not activate after pressing POWER. Use the same type and replace all four batteries together. Remove the batteries if the monitor will remain unused for more than one month. Dispose of batteries through the collection or recycling system required in your area.

Set the Date and Time

1. After batteries are installed, the year begins flashing.
2. Press M1 to advance to the correct year, then press M2 to confirm.
3. Set the month, date, hour, and minutes in the same way.
4. After the minutes are confirmed, the monitor exits setup, briefly displays its shutdown message, and turns off.

Reset the date and time whenever the batteries are initially installed or replaced.

Select the Ambient-Temperature Unit

1. After the date and time are set, press M1 to choose Celsius or Fahrenheit.
2. Press M2 to confirm the selection.
3. With the monitor powered off, press MODE to view the ambient temperature and date/time.

The ambient-temperature reading is provided for reference and is not intended as a precision environmental measurement.

Set Measurement Alarms

The alarm function provides reminders for up to three daily measurement times.

1. Press MODE to enter the alarm-setting function.
2. Continue selecting the alarm option until alarm 1, 2, or 3 is shown.
3. When the hour flashes, use M1 to select the hour and M2 to confirm it.
4. Use M1 to select the minutes and M2 to confirm them.
5. Use M1 to switch the selected alarm ON or OFF, then press M2 to save the choice.
6. Repeat the procedure for additional alarms if required.
7. Press POWER to turn the monitor off.

An enabled alarm can sound at its scheduled time even when the monitor is powered off.

Apply the Upper-Arm Cuff

1. Sit at a table with both feet flat on the floor.
2. Place the cuff on a stable surface with the tube pointing upward and away from you. The metal ring should be on the left side of the tube.
3. Open the cuff by pulling or rolling its lower portion toward the right. Leave it partially rolled so it forms a cylinder; do not completely unwrap it.
4. Slide the left arm into the cuff cylinder.
5. Position the lower edge of the cuff about one inch above the elbow crease.
6. Reach beneath the arm with the opposite hand and pull the cuff end toward the body.
7. Secure the cuff so it is snug but comfortable. One finger should fit between the arm and cuff.
8. Connect the cuff tube to the monitor only after the cuff is positioned on the arm.

If the left arm cannot be used, the cuff may be applied to the right arm by adapting the same positioning method. A healthcare professional can help identify the most appropriate arm and demonstrate correct cuff placement.

Take a Blood Pressure Reading

1. Place the monitor on a flat, stable surface where the display is easy to see.
2. Insert the cuff-tube connector into the air socket on the left side of the monitor.
3. Rest the elbow on a solid surface with the palm facing upward.
4. Raise the arm until the cuff is level with the heart, and relax the hand.
5. Press POWER. The display performs a self-check and then shows the previous reading, or zero if no reading is stored.
6. The cuff inflates automatically. Keep still and do not speak while pressure is being measured.
7. Watch for the flashing heartbeat symbol during detection.
8. When measurement is complete, systolic pressure, diastolic pressure, pulse rate, and applicable indicators appear together.
9. Press POWER to turn the monitor off, or allow it to shut down automatically after approximately two minutes.

The monitor may reinflate during a reading if the initial pressure is insufficient. This can occur when the measured blood pressure is higher than the initial inflation level.

Understand the Display Indicators

• Heartbeat symbol: Indicates that the monitor is detecting pulse activity.
• Irregular-heartbeat symbol: Indicates that an irregular rhythm was detected during the reading. Frequent appearances should be discussed with a healthcare professional.
• WHO indicator: Places the result within a reference range intended for general guidance, not diagnosis.
• Low-battery symbol: Indicates that the batteries should be replaced.
• Memory symbol and number: Identify stored readings and their position in the selected memory bank.
• Average symbol: Indicates the average of the three most recently stored readings in the selected bank.
• Alarm symbol: Shows that a measurement reminder is configured.

Memory Function

The BPM65 Arm Type Blood Pressure Monitor has two independent memory banks. Each bank stores up to 60 complete readings, for a total capacity of 120 readings. When a bank is full, the oldest entry is replaced by the newest one.

Recall Stored Readings

1. Press and release M1 or M2 to choose the desired memory bank.
2. The monitor first shows the average of the three most recent readings in that bank.
3. Press the same memory button repeatedly to move from the newest stored result toward older results.
4. Each entry can include systolic pressure, diastolic pressure, pulse, date, time, WHO indication, and any irregular-heartbeat alert.
5. Press POWER to leave memory review at any time.

Clear Stored Readings

With the monitor powered off, press and hold the selected MEMORY button until “CLr” appears. This deletes the readings stored in that memory bank according to the monitor’s clearing function.

Cleaning and Maintenance

• Wipe the monitor with a slightly damp cloth.
• Do not use detergents, solvents, or abrasive cleaners.
• Never immerse the monitor or hold it under running water. Liquid can enter the housing and damage the electronics.
• Do not place heavy objects on the monitor.
• For home disinfection, 75% ethanol or isopropyl alcohol may be used appropriately on compatible external surfaces. Avoid saturating the monitor or allowing liquid to enter openings.
• Store and transport the device within the specified temperature, humidity, and atmospheric-pressure limits.
• Accuracy should be checked by the manufacturer or an appropriate service facility every two years to help detect sensor drift.

Troubleshooting

• Nothing appears when POWER is pressed: Replace all batteries. If the batteries are present, check that their polarity matches the markings.
• Low-battery symbol remains visible: Install a complete set of new AA alkaline batteries. Cold conditions can temporarily reduce battery performance.
• No reading is produced: Check the batteries, cuff connection, cuff fit, arm position, and tube for restriction. Relax and repeat the measurement.
• Err 00: The monitor detected no pulse or an insufficient pulse signal. Remove heavy clothing, remain still, and try again.
• Err 01: The cuff is not secured correctly. Reapply it with the lower edge about one inch above the elbow and repeat the reading.
• Err 02: The reading was not reliable. Rest, relax, and measure again.
• Err 03: Inflation or deflation was unsuccessful. Check the cuff placement, tube connection, and cuff fit before repeating the measurement.
• Memory error: Remove the batteries briefly to restart the monitor, reinstall them, and take a new reading.
• Unexpectedly high or low result: Confirm that the cuff is correctly positioned, the arm is at heart level, and the required rest period was observed. Blood pressure naturally changes throughout the day.
• Unexpected pulse result: Avoid movement, conversation, exercise, and measurement immediately after returning from outdoors.
• Monitor turns off: Automatic shutdown is normal after approximately two minutes without operation. Press POWER to begin another reading.
• Cuff reinflates: The monitor may increase pressure automatically when the initial inflation level is not enough. Relax and allow the measurement to finish.

If unusual readings continue after correct preparation and cuff placement, consult a physician or trained healthcare professional rather than attempting to adjust the monitor.
