An irregular heartbeat is present when the heart
rhythm deviates by more than 25 % from the
median heart rhythm. The contraction of the
heart muscle is stimulated by electrical signals.
A disorder of these electrical signals is called an
arrhythmia. This may be due to a genetic predis-
position, stress, age, lack of sleep, exhaustion or
similar factors. A doctor can establish whether
an irregular heartbeat is the result of an arrhyth-
mia.
Power supply (batteries)
Observe the polarity labels plus (+) and minus (-).
Only use high-quality batteries (see specification in Chapter 12
’Technical data’). If you use low-quality batteries, we can no
longer guarantee the specified number of measurements.
Never mix old and new batteries or batteries from different
manufacturers.
Remove flat batteries immediately.
Replace batteries if the battery symbol
remains illumi-
nated.
Always replace all the batteries at the same time.
If you do not intend to use the monitor for a longer period
of time, you should remove the batteries to prevent possible
leakage.
Information about batteries
Choking hazard
Small children could swallow batteries and suffocate on them.
Keep the packaging, batteries and the monitor out of the
reach of children.
Risk of explosion
Do not throw batteries into a fire.
Batteries must not be charged or short-circuited.
If a battery has leaked, wear protective gloves and clean the
battery compartment with a dry cloth. If liquid from a battery
cell comes into contact with skin or eyes, clean the affected
area with water and seek medical attention if necessary.
Protect batteries from excessive heat.
Do not disassemble, open or crush batteries.
