Parts Identification

Familiarize yourself with the monitor's components.

Main Unit: Contains the display and control buttons.
Cuff with D-Ring: Wraps around your upper arm. The air tube connects to the left side of the unit.
START/STOP Button: Initiates and stops the measurement.
MEMORY Button: Recalls stored readings.
USER Button: Selects User 1 or User 2 for memory storage.
Display: Shows systolic/diastolic pressure, pulse, icons, and date/time.
AC Adapter Jack: For optional AC power (adapter sold separately for some models).

CAUTION! Ensure the cuff is the correct size for your arm. An improper fit can cause inaccurate readings.

Setting Up the Monitor

Power on and set the date/time before first use.

Insert Batteries: Open the battery compartment on the back and insert 4 AA batteries, matching the polarity (+/-).
Set Date & Time: Press and hold the MEMORY button for 3 seconds until the year flashes. Use the START/STOP button to adjust values and the MEMORY button to confirm and move to the next setting (month, day, hour, minute).
Apply the Cuff: Sit comfortably. Place the cuff on your bare upper arm. The artery marker (▼) should align with your brachial artery. Pull the end of the cuff through the D-Ring and secure snugly.
Positioning: Rest your arm on a table so the cuff is at heart level. Sit still with feet flat on the floor and back supported.

Tip: Avoid taking measurements immediately after eating, bathing, exercising, or consuming caffeine/alcohol. Rest for 5 minutes first.

Taking a Measurement

Follow these steps for an accurate reading.

Select User: Press the USER button to select User 1 or User 2. The corresponding icon will appear.
Start Measurement: Press the START/STOP button. The cuff will inflate automatically.
Remain Still: Sit still and do not talk during inflation and measurement. The monitor detects your pulse.
Reading Display: When measurement is complete, the cuff deflates. Your systolic pressure, diastolic pressure, and pulse rate will display.
Hypertension Indicator: If your systolic reading is 135 mmHg or higher, or diastolic is 85 mmHg or higher, the hypertension symbol will appear.
Power Off: The monitor turns off automatically about 1 minute after the reading is displayed.

WARNING! Do not inflate the cuff when it is not wrapped around your arm.

Understanding Your Readings

Interpret the symbols and values on the display.

Systolic Pressure: The higher number (e.g., 120). Pressure when the heart contracts.
Diastolic Pressure: The lower number (e.g., 80). Pressure when the heart relaxes between beats.
Pulse Rate: Beats per minute (e.g., 72).
Irregular Heartbeat Icon: Appears if an irregular rhythm is detected during measurement.
Body Movement Icon: Appears if excessive movement is detected. The reading may be inaccurate.
Hypertension Indicator: Appears if reading is at or above 135/85 mmHg.
User Icon (1 or 2): Indicates which user's memory is active.
Average Value Icon: Appears when the displayed value is the average of the last three readings.

Memory Recall Function

Review past measurements stored in memory.

Press the MEMORY button. The most recent reading for the selected user appears with date and time.
Press the MEMORY button repeatedly to scroll through all stored readings for that user (up to 100).
To view the other user's memory, first press the USER button to switch users, then press MEMORY.
To calculate the average of the last three readings taken within the last 10 minutes, press and hold the MEMORY button for 3 seconds while a reading is displayed. The average icon will appear.
To clear all memory for the selected user, press and hold the USER button for 3 seconds while in memory mode. "CLR" will flash, then all data for that user will be erased.

Note: Memory is retained even when batteries are removed.

Care & Maintenance

Proper care ensures long life and accurate readings.

Cleaning: Wipe the main unit and cuff with a soft, dry cloth. Do not use alcohol, benzene, thinner, or abrasive cleaners.
