Frequently Asked Questions - GP450SP G-Tech
How do I measure my blood pressure correctly?
Sit comfortably with your back supported and feet flat on the floor. Place the cuff on your bare upper arm about 2–3 cm above the elbow. Keep your arm at heart level and relax during the measurement. Do not talk or move while the monitor is working.
What does the irregular heartbeat indicator mean?
The irregular heartbeat icon appears when an unusual rhythm is detected during measurement. It is a warning and not a diagnosis. If the symbol appears frequently, consult your doctor.
How do I maintain the cuff?
Wipe the cuff with a dry, soft cloth after use. Do not wash it in water or use chemical cleaners. Allow it to air dry completely before storing. Avoid bending the cuff tightly.
Can I use the monitor with both batteries and an AC adapter?
Yes, the device supports 4 x AA batteries (1.5V) as standard. An optional AC adapter (DC 6V) can be used for continuous power. When using the adapter, remove the batteries to prevent leakage.
How many readings can be stored and how do I retrieve them?
The monitor stores up to 120 readings per user for two users. To recall, press the memory button to view averages, then navigate to individual readings. The last reading is shown first.
What is the WHO classification indicator?
The WHO classification indicator compares your blood pressure values to the World Health Organization standard ranges. It shows a colored bar on the display (green, yellow, orange, or red) to help you interpret your results quickly.
How do I clean the device?
Switch off the monitor and remove batteries if cleaning the main unit. Wipe the outer surface with a dry, lint-free cloth. Do not use water, alcohol, or abrasive cleaners. Keep the cuff clean by wiping with a dry cloth.
Are replacement cuffs available?
Yes, replacement cuffs can be ordered from G-Tech authorized service centers. Ensure you select the correct cuff size (22–42 cm) that matches your arm circumference for accurate measurements.
Why does the monitor display an error message?
Error messages may appear due to improper cuff placement, body movement during measurement, or low batteries. Check the cuff connection, relax, and try again. If the error persists, replace the batteries or consult the user manual.
What does the average of the last 3 readings mean?
The average function calculates the mean of your three most recent measurements taken in the same period. This helps reduce daily variation and gives a more stable picture of your blood pressure, especially when taken at the same time each day.
