Frequently Asked Questions - MA100 G-Tech

How do I correctly position the cuff?

Place the cuff on your bare upper arm about 2-3 cm above the elbow. The tube should be aligned with the center of your palm. Sit upright with your arm resting on a table at heart level. Wait at least 5 minutes before measuring.

What does the irregular heartbeat symbol mean?

The irregular heartbeat indicator lights up if an arrhythmia is detected during measurement. This is a warning and not a diagnosis. Consult your doctor if it appears frequently.

How do I clean the monitor and cuff?

Use a soft, dry cloth to clean the monitor body. The cuff can be wiped with a damp cloth and mild soap, then air-dried. Never immerse any part in water or use chemical cleaners.

Why do I get different readings each time?

Blood pressure varies naturally. Ensure you are relaxed, seated correctly, and the cuff is at heart level. Wait at least 3 minutes between readings. Take multiple measurements at the same time each day for consistency.

How many readings can the memory store?

The device stores up to 90 readings per user for two users (User A and User B). The date and time are recorded automatically.

What type of batteries does it use and how long do they last?

It uses 4 x AA alkaline batteries. Under normal use (2 measurements per day), batteries last approximately 3 months. The device also supports an optional AC adapter (6V, 600mA).

What does an 'Err' message mean?

Common error codes: Err1 (weak signal - check cuff connection), Err2 (movement during measurement - stay still), Err3 (cuff not inflated properly - reseat cuff). Refer to the manual for all codes.

Can I use this monitor if I have atrial fibrillation?

The monitor can detect irregular heartbeats but is not designed for patients with severe arrhythmias like atrial fibrillation. Consult your doctor for guidance on home monitoring.

How does this monitor compare to a doctor's manual reading?

This device uses the oscillometric method, which is clinically validated to be equivalent to auscultatory measurements. However, readings may differ slightly due to home conditions. Always share your readings with your healthcare provider.

What is the warranty period and how do I claim it?

The G-Tech MA100 comes with a 2-year warranty against manufacturing defects. To claim, contact G-Tech customer support with proof of purchase. Do not attempt to open the device yourself.
