Example: If the blood pressure reading was taken and the sounds started at 148 mmHg, then the offset is +2. If the sounds started at 152 mmHg, the offset is –2. For this example, assume that the sounds started at 148 mmHg. Press and hold the Calibration key until the systolic correction window appears. (See figure 12.) Using the arrow down key set the correction to +2. Set the diastolic offset. Example: If the blood pressure reading was taken and the sounds stopped at 72mmHg, the offset is –2; or if the sounds stopped at 68 mmHg, the offset is +2. For this example, assume that the sounds stopped at 72 mmHg. From the systolic window, press the Menu key to change the diastolic window. (See figure 13.) With the arrow up key, set the correction to –2. Press the Menu key again and the message “CALIBRATION COMPLETE” will appear. The main menu window willbe displayed.
