4.2 information about body temperature
It is a common misconception that 37 °c is the „normal body temperature". It is actually
the case that 37 °c is the average body temperature. the normal body temperature is
in a range that varies with age, gender and measuring point. Furthermore, the body
temperature fluctuates over the course of the day. It is usually lower in the morning,
higher in the afternoon and goes down a little again in the evening. Other factors that
affect body temperature may be: the patient's particular activity, metabolic rate or
medications taken. the normal body temperature also tends to drop with increasing
age.
the normal temperatures are listed in the following table according to the age of the
patient and measuring point. temperatures measured at different parts of the body,
even if they are measured at the same time, must not be directly compared with one
another, as body temperature differs between measuring points.

4.3 pulse signal
a detected pulse beat is indicated with an acoustic signal at the moment of systole;
the signal's pitch changes with the value of the oxygen saturation. this allows you
to acoustically track the pulse rate and the course of the oxygen saturation without
continuously having to keep an eye of the device's display. the pulse signal can be
deactivated in the settings menu (setup button), see section 6.2.
4.4 Built-in li-ion battery
the device's battery permits mobile, battery-supplied operation. the frequency of the
blood pressure measurements affects the operating time without a power connection.
with blood pressure measurements taken at 10-minute intervals, the
up to 40 hours in battery-operated mode, with the optional predictive thermometer
approx. 20 hours. a symbol on the display indicates the battery's remaining charge.
connect the device to a mains socket with the included mains adaptor to charge it.
It takes about 8 hours to recharge a fully empty battery. You can operate the device
without problem while it is charging. no memory effect occurs due to the use of Li-ion
technology.
