Charging the custo guard ECG transmitter
IMPORTANT: Charge the custo guard ECG transmitter before using it for the
first time!
Connect the charger to the mains with the plug-in power supply unit.
The charger is ready for operation when the LED on the charger lights up orange .
Only use the supplied power supply unit for the charger!
Place the custo guard ECG transmitter onto the charger . The direction of
insertion is based on the shape of the housing. The LED in the ECG transmitter
indicates the charging status. Take the ECG transmitter out of the charger when it
is fully charged.

Charging complete
For technical reasons, it can occur that an ECG transmitter that is indicated to be
“completely charged” (green LED) shows the status “Charging” (red LED) again if it
is removed and then reinserted into the charger.
Charging time and runtime
When fully discharged, the maximum charging time is approx. 3 hours. At a
sampling rate of 1 kHz, the maximum runtime is approx. 3 days, in standby approx.
100 days. The rechargeable battery capacity or the maximum runtime decreases over
time (80 % of the initial capacity after 300 charging cycles)
1)
.
Frequency of charging cycles
We recommend charging the devices after each recording.
Clean, disinfect and dry the devices before recharging.
CAUTION:
Charging damp ECG transmitters (perspiration, disinfectants)
will lead to the oxidation of the electric contacts in the charger.
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.
