1) The battery runtime is
dependent among other things on
the mode of reception of the
receiver, the distance and obstacles
between the receiver and
transmitter (condition of the
transmission path) and the age and
condition of the battery.
After 300 or more charging cycles,
the battery has a capacity of 80 %
of the initial capacity.
Defi nition of charge cycle:
During a charge cycle the entire
battery power is used, however,
this does not have to occur in a
single charging operation. For
example, you can use a device for
several hours on a particular day,
use approximately half the capacity,
and then fully charge it again. If
the same procedure is repeated on
the following day, this is equal to
just one charging cycle and not two
charging cycles. It can therefore take
a few days for a charge cycle to be
fully completed.
2) When carrying out recordings
with custo screen 400, the sampling
rate is 125 Hz.
3) If the custo guard is to be
stored for a longer period of time, it
should be recharged regularly (our
recommendation: every 3 months to
approx. 60%).
