Charging custo watch and custo guard
Connect the custo docking station with the micro USB cable to the switched-on
PC. Only use the supplied micro USB cable. Alternatively, the custo docking station
can be connected to the power supply with the plug-in power supply unit.
Place the custo watch onto the custo docking station. The custo watch must engage
noticeably and be firmly seated on the custo docking station, with the grey button
pointing downwards . The custo guard 3 ECG transmitter is also charged in the
custo docking station. The direction of insertion is determined by the shape of the
housing (the opening of the custo med logo points upwards
).

The LED on the custo guard 3 ECG transmitter indicates the operational readiness
of the system when both devices are in the custo docking station.

If the grey button on the custo watch is pressed while both devices are in the custo
docking station, the rechargeable battery capacity of both devices is shown on the
display. If there is sufficient rechargeable battery capacity for a 24-hour recording
period, a checkmark appears for the corresponding device. If the rechargeable bat-
tery capacity is less than 24 hours, the current charge status is displayed. If there is
no custo guard 3 ECG transmitter on the custo docking station or an incorrect custo
guard 3 (i.e. one which is not connected to the custo watch), the display shows
guard: ---. Place the correct custo guard 3 onto the custo docking station.
Frequency of charging cycles
We recommend charging the devices after each recording. Clean, disinfect and dry
the devices before recharging.
1) The rechargeable battery
runtime is dependent, among
other things, on the distance and
obstacles between the receiver
and transmitter (condition of the
transmission path) and the age
and condition of the rechargeable
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) Prerequisite:
custo watch and custo guard have
already been connected with each
other in custo diagnostic and the
serial number of the custo guard
ECG transmitter is stored in the
custo watch. The devices are
connected during the start
procedure (refer to Part 3, Holter -
description of software, chapter
“Performing a holter recording”).
It is only possible to display
operational readiness if no recording
is currently in progress and both
devices are in the custo docking
station that is connected to the PC.
IMPORTANT:
Charge
the devices
before
first use!
