If the symbol is displayed and does not disappear,
measurement is no longer possible. Replace all the batteries.
Once the batteries have been removed from the device, the
date and time must be set again. Any saved measured values
are retained.
Operation with the mains part
You can also operate this device with a mains part (not in-
cluded in delivery). However, before connecting the device
with the mains part, please ensure that you have removed the
batteries from the device. During mains operation, there must
not be any batteries in the battery compartment, as this could
damage the device.
• To avoid any potential damage, the device may only be
operated with a mains part that meets the specifications
described in the chapter "Technical specifications".
• Furthermore, the mains part must only be connected to
the mains voltage that is specified on the type plate.
• Insert the mains adapter into the connection provided
for this purpose on the rear side of the blood pressure
monitor.
• Then insert the mains plug of the mains part into the
mains socket.
• After using the blood pressure monitor, unplug the mains
part from the mains socket first and then disconnect it
from the blood pressure monitor. As soon as you unplug
the mains part, the blood pressure monitor loses the date
and time setting but the saved measured values are re-
tained.
