provide technical information, spare parts and units to authorized dealers.
Technical inspection procedures which should be done at least every two years, can be
performed either by the manufacturer or by an authorized repair service in accordance with the
regulations governing manufacturing of medical products.
Checking pressure accuracy
When using a rubber pump, do not apply a pressure of 280 mmHg or higher to
the monitor or inspection equipment (UM-102, accurate mercury
sphygmomanometer or aneroid gauge).
Perform the inspection only as described below or the setting values and
function settings may be changed.
After inspection, check that the air connector plug is inserted into the blood

applied and measurement is not possible. When inserting the plug, push in until
you hear a click.
