5.  Other possible malfunctions and their elimination

If problems occur when using the device, the following points should be checked and if 

necessary, the corresponding measures are to be taken:

Malfunction

The sound transmission is poor, distorted or 
there is extraneous noise.

The pressure does not rise although the bulb 
is pumping.

The deflation rate can not be set to 
2 - 3 mmHg/ sec. by adjusting the air release 
valve.

Pointer is not at 0 +/- 3 mmHg at rest.

Remedy

1.  Check the earpieces if they are plugged or 

cracked. If not, make sure they do not fit 
poorly as worn.

2.  Check the tube if it is broken or twisted.
3.  Check the bell and diaphragm of chestpiece 

if there is any crack.

4.  Make sure the chestpiece is in proper 

contact with skin and over brachial artery 
during measuring.

  Clean or replace any defective parts if 

found to avoid inaccurate reading.

1.  Make sure that the valve is closed.
2.  Make sure the cuff is properly connected to 

manometer.

3.  Check if the cuff, tube and bulb is leaky. 

Replace the defective parts if any.

1.  Disassemble the bulb from manometer to 
  check if there is any blockage in the airway
  of the valve. Clean the blockage and try
  again. If it still does not work, replace it to
  avoid inaccurate reading.
1.  Make sure that the valve is open for zero 

check.

2.  If still more than 3 mmHg deviation, contact 

your dealer to recalibrate the manometer.
