or Er2 appears in the display),
• the cuff is too tight or too loose (Er3 or Er4 appears in the
display),
• the inflation pressure is higher than 300 mmHg (Er5 ap-
pears in the display),
• inflation takes longer than 3 minutes (Er6 appears in the
display),
• there is a system or device error (ErA, Er0, Er7 or Er8 ap-
pears in the display),
