Effectively monitor your blood pressure with the TB251 electronic upper arm blood pressure monitor, a Class IIA medical device designed to combine reliability, simplicity and comfort of daily use.

Equipped with oscillometric technology, the TB251 accurately measures systolic and diastolic pressures, as well as heart rate. Its medical certification guarantees safe and accurate blood pressure monitoring, ideal for regular home use.

Designed for family or shared use, the TB251 can record up to 199 measurements for each of its two user profiles, while offering a guest mode for occasional blood pressure readings without data recording. Perfect for tracking the health of multiple household members, or for occasional use.

The interface has been designed for simple and immediate reading: its large LED screen displays the results clearly, while the WHO color indicator allows a quick assessment of the blood pressure level (normal, high, etc.) without requiring medical knowledge.

To ensure reliable measurements every time, the TB251 incorporates advanced assistance features:
– Alert in case of incorrect positioning of the cuff,
– Reporting the risks of measurement errors due to movements or speech during measurement.

Its flexible, adjustable cuff (from 22 to 42 cm) adapts to a wide variety of body shapes, ensuring optimal comfort for each user. Compact and practical, the TB251 is powered either by 4 AAA batteries or occasionally via a USB-C cable, to adapt to your habits, whether you are at home or on the go.

Supplied with a velvet carrying pouch, this blood pressure monitor goes everywhere with you and allows you to easily monitor your cardiovascular health.

PREPARATION BEFORE USE
I. POWERING ON THE PRODUCT INSERTING THE BATTERIES
1. Open the battery cover according to the method shown in the figure.
2. Place 4 AAA batteries in the battery compartment, respecting the direction of the + and - poles.

USB-C POWER CONNECTION
In addition to batteries, power can also be supplied by plugging into an external DC 5V, 1A power supply via a USB-C port. (Power cable is not included.)

II. USER SELECTION
This blood pressure monitor offers three user profiles: two users with a memory capacity of 199 recordings each, as well as a guest mode.
When the device is off, press the 'user selection' button corresponding to the chosen user: user 1, user 2, guest. Note that the guest user's data will not be stored.

III. SETTING THE UNIT DISPLAY
There are two units for displaying blood pressure: mmHg and kPa.
The default unit is mmHg.
When the device is off, press the 'start/stop' button for about 5 seconds to access the unit selection. Press the 'start/stop' button to switch between mmHg and KPa, then press the 'start/stop' button to confirm the selection.

TAKING MEASUREMENT
I. POSITION THE CUFF
The armband is placed on the left arm.
However, if your doctor has diagnosed you with poor circulation in that arm, or if you are in one of the situations explained in the "Warnings" section on page 9, you can use your right arm.
1. Remove all jewelry, such as watches and bracelets.
Roll up or roll up your sleeve to expose the skin. Make sure your sleeve is not constricting your arm.
2. Connect the cuff to the monitor by inserting the air plug into the Air Jack.
3. Place your hand through the cuff loop. Pull the cuff until it reaches your upper arm.
4. Make sure that:
• the lower edge of the cuff is located between 2 and 3 cm above the elbow,
• that the pipe is on the outside, aligned with your middle finger.
5. Adjust your cuff.
Tip: Your cuff is tight if you can insert a finger between your arm and the cuff.

II. SET UP CORRECTLY
To take a measurement, you should be relaxed and comfortably seated in a room at a comfortable temperature.
• Sit upright in a comfortable chair with your back resting on the backrest.
• Do not cross your legs and keep your feet flat on the floor.
• Your arm rests comfortably on a table or flat surface, palm up.
• Your cuff should be placed on your arm at the same level as your heart.
• Relax as much as possible.

III. TAKING THE VOLTAGE
This product uses the oscillometric measurement method to detect blood pressure. Before each measurement, the unit establishes a "zero pressure" equivalent to air pressure. Then, the product begins to inflate the cuff, while the unit detects the pressure oscillations generated by the pulses, beat by beat, which are used to determine the systolic and diastolic pressures, as well as the pulse rate.
1. Press the 'start/stop' button to turn on the device and take the blood pressure.
2. The blood pressure monitor begins to inflate for measurement and displays “00”.
3. Inflation and measurement
The value displayed on the screen increases, before slowly decreasing, the heart rate symbol flashes.
4. Displaying results and storing them
Once the measurement is complete, the systolic pressure, diastolic pressure and pulse rate are displayed on the screen.
Consult your doctor if you get unexpected results.

IV. TURN OFF THE DEVICE
Press the 'start/stop' button to turn off the upper arm blood pressure monitor. Otherwise, the blood pressure monitor will automatically turn off after 1 minute.
