CARE AND MAINTENANCE
Protection and cleaning
BTL-08 ABPM ambulatory blood pressure recorders are not specially protected against spills or ingression of water or
other liquids. Do not immerse the recorder in water or any cleaning fluid, and protect it from spills and splashes. Do
not expose it to heavy rain or steam, and do not wear it in a wet environment e.g: shower, bath, or swimming pool. In
case of minor effects of a wet environment, wipe off water drops with a dry cloth. Keep the recorder in a normal dry
room for at least one hour before use if condensation is suspected. In case of ingress of water in the recorder, remove
batteries from the unit, and refer the unit to authorized service. Never place a recorder unit in a disinfecting or
sterilizing machine! A recommended means of cleaning is to wipe the recorder with a disinfectant cleaning tissue, e.g.,
Henkel Ecolab Incides, or a similar product. Alternatively, wipe with a slightly damp cloth then dry it with an antistatic
tissue. Do not expose recorders to extreme heat or radiation, including long exposure to direct strong sunlight.
Regular checks, warranty, service
Verification of pressure measurement accuracy is recommended biannually. BTL-08 ABPM recorders are covered by
a two-year warranty under general warranty conditions of BTL Industries Ltd., see relevant section. This warranty
does not cover any malfunction or defects arising from improper use, the use of inadequate accessories, accident,
theft, or use of the device outside operating environmental specifications or intended measurement range. Removing
the closing label from the back side of the device voids this warranty. There are no user serviceable parts inside BTL
recorders; they contain high complexity electronic and fine mechanical components. If you have any problems, please
refer the recorder to qualified service personnel. Contact BTL or your distributor for service information.
Roll-out
BTL-08 ABPM recorders include an internal NiCd coin cell which may fall under the category of hazardous waste and
should be disposed of properly. The device should be handled at roll-out as normal electronic waste.
Bateries
BTL-08 ABPM ambulatory blood pressure recorders operate with two 1.5V AA batteries 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 recorder,
and they may damage the recorder, or 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 recorder, 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 recorder 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 BTL-08 ABPM recorders, it is advised to check their voltage before
programming the recorders. 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.)
