2.7. Batteries

The OMRON M24/7 ambulatory blood pressure monitor operates with two 1.5V

AAbatteries or two 1.2V AA rechargeable batteries. Use only standard long- life (alkaline) batteries, or standard NiCd or NiMH rechargeable batteries of the proper size. Do not use lithium batteries. Do not mix different battery types, do not mix new and old batteries. Never use batteries of low or unknown quality or pre- used batteries, as they may not cover the power needs of the monitor, and they may damage the monitor, as they may contain acidic electrolytes which may leak and corrode electronic components. Never use batteries damaged in any way. Should the batteries run down during a monitoring session, they can be replaced. Monitoring will continue and data will not be lost. If you do not use the monitor, it is advisable to remove batteries since they may run down due to the constant small power consumption of the integrated circuits of the device. Data in the monitor are not lost even if batteries run down or are removed. Used batteries may fall under the category of hazardous waste and should be disposed of properly.

Important! It is strongly recommended to use freshly charged accumulators or new batteries with every patient so that batteries do not run down during monitoring, even in case of very high blood pressure values and/or a long monitoring session. After inserting batteries in M24/7monitors, it is advised to check their voltage before programming the monitors. Do not start a new monitoring session with low batteries. The typical voltage for two fully charged rechargeable batteries should be over 2,5 V, and for fresh alkaline batteries, over 3 V. It is possible to check battery voltage with the START button. (Please check the Using the buttons section for more details.)

Important! If a monitor is not used for a long period, the in-built backup cell ensuring the operation of the internal clock may get discharged. In this case keep freshly charged batteries in the monitor for at least one day; this will recharge the backup cell. It is possible to use the monitor afterwards. If the backup cell is not properly charged, the internal clock may work incorrectly, and the monitor may not start measurements in due time.

A set of new, high capacity batteries will enable the OMRON M24/7 monitor to
perform 250 blood pressure measurements during a 24-48 hours long monitoring
session. If you opt to use alkaline batteries, choose high capacity, long-life
products to enable reliable operation. A small crossed battery sign on the LCD
shows low battery voltage.	15
