appear if:
• No pulse rate detected ( )
• You speak or move during measurement ( )
• The cuff was not attached correctly or the cuff is fastened too tightly or loosely and measurement
takes longer than 25 seconds ( )
• A system or device error occurs ( )
• Air pressure is higher than 300 mmHg (
• Batteries are almost depleted ( )
In such cases, repeat the measurement. Do not move or speak. If necessary, replace the batteries.
