2. Operating Instructions 2.1. Working with the OMRON M24/7 Unit The OMRON M24/7 device is a compact, lightweight monitoring unit typically worn by the patient for 24 hours. The OMRON M24/7 operates with two AA size batteries. The memory is capable of storing more than 600 measurements. Stepwise pressure de ation ensures quality measurements, even if disturbing environmental factors occur. You may nd the battery compartment and the rating label on the backside housing.

Switching the device off Press and hold the START button for more than 10 seconds then release it when two horizontal segments appear on the LCD, this way the OMRON M24/7 will be switched off. If you do not release the button in 2 seconds after the two horizontal segments appeared, the monitor will return to normal operation. This feature helps to avoid unintended power-off. The device can only be switched on manually. While the monitor is switched off normal functions are not available, ev

2.3. Overview Display The OMRON M24/7 shows important status information, the processes and results of individual readings on its LCD. The most important displays are listed here. In addition to these, a lot of extraordinary situations and errors have their own code displayed on the LCD. These codes are stored together with recorded data and listed in the OMRON BP Tracker Software. This helps service personnel in case of support issues. Normal status: time is Night mode: time is displayed

The monitor must be programmed with the OMRON BP Tracker Software installed on the computer (for details see Software Manual). Once the pre- programmed time is reached, the monitor will start operating automatically and perform blood pressure measurements based on the monitoring plan. To obtain reliable BP readings, certain rules must be observed. 2.4. Rules of Monitoring 1. Inform the patient about the goal and expected results of the monitoring. Provide an event/patient diary and rules to

A successful monitoring session consists of the following steps: 1. Connecting the OMRON M24/7 monitor to the PC (First connection only – not required to repeat with each session) 1. Connect the optical interface, which was delivered with the device, to the USB port of the PC. 2. The other side of the optical USB interface cable, which is a two-point plastic connection, should be connected to the socket of the OMRON M24/7, in a way that the red plastic ring is directed to the lower side of

2.6. Manual Programming The OMRON M24/7 can be programmed with using its buttons, without using a PC. Programming Options There are three different measurement plans which may be selected in case of manual programming. These plans are stored in the device’s inside memory and they cannot be changed. The rst plan which is also the default one in the OMRON BP Tracker Software, measurements every 15 minutes during daytime and 30 minutes during night. The second one provides less frequent me

In order to change batteries, take the monitor out of the holder carry pouch and remove the battery compartment cover on the back-side. Place two new, long- life AA alkaline batteries or two properly charged, high capacity AA rechargeable batteries into the compartment as shown in the polarity drawing. Close the compartment. 2.8. Cuffs and their application The OMRON M24/7 comes with 2 cuffs, normal and large adult size (see below). The bladders are made of neoprene and are latex-free. It i

Note: Note: It is recommended that the cuff be applied as tightly as acceptable for the patient. A too loose cuff will cause much longer blood pressure measurement times and possibly aborted measurements. With an overly loose cuff, the monitor must pump to tighten the cuff on the arm and then it must reach the pressure necessary for measurement. This causes considerable inconvenience for the patient and results in less data for evaluation. If the patient removes the cuff for a period durin
