?? The adult DURA-CUF
™
range supplied for use with this Monitor may be cleaned by hand washing
in warm soapy water. Care should be exercised, however, to ensure that no water enters the cuff
or cuff hoses at any time. In the event water accidentally enters the cuff, passing air through the
cuff will dry it.
?? The neonatal cuffs are supplied for single use and should be discarded if they become soiled.
?? Do not immerse hoses.
?? Do not immerse cuffs without prior application of cuff hose caps.
CAUTION
?? Moisture or foreign substances introduced into the pneumatic system can cause damage to the
unit. Calibration equipment should always be kept dry and free of particulate matter.
?? The probe holder may be removed and cleaned with a mild detergent. The probe holder may be
immersed during cleaning.
?? Do not immerse temperature calibration plug.
?? The probe may be cleaned with an alcohol solution. Use a cloth or sponge, just damp, not wet,
and avoid getting any liquid into the interior of the probe.
Checking of Calibrations
Refer to section 3.3 for instruction on the procedures required to check each of the parameter calibrations.
3.1.3 Care of the Storage Battery
It is best to keep the battery charged as fully as is practical and never store the monitor with the battery in a
discharged condition. When the battery will no longer hold a charge, remove and replace with one of the
same part number.
To charge the battery, connect the supplied power converter to the monitor's rear panel, then plug the
converter’s mains lead into an appropriate AC receptacle. The battery will charge regardless of the position
of any other monitor switches.
A battery that is completely discharged can be fully recharged by the monitor within eight hours. Charging
will take place with the monitor switched on or off, as long as it remains connected to an external AC power
source via the supplied power converter.
The expected lifetime of the battery largely depends on the way in which the instrument is used. If the
battery is allowed to completely discharge before being fully recharged, the battery should survive around
two hundred recharge cycles. If the battery is used in such a way that it never becomes more than one third
discharged and is fully recharged whenever possible, it can survive up to twelve hundred cycles. This
means that by thoughtful usage, the lifetime of the battery can be extended up to six times.
PRECAUTIONS
?? To ensure that the battery will be ready for portable operation, keep the unit connected to a mains
supply whenever possible.
?? Repeated failure to fully charge the battery will result in a significant reduction in battery life.
Avoid storing batteries at temperatures above 77° F (25° C). High storage temperatures can dramatically
increase the rate of self-discharge of the battery.
