Warm start
During a warm start the system is reinitialized and the configuration data are loaded. They
are stored in the RAM (in normal memory and backing memory) and in the EEPROM and
are protected in both cases by a checksum. Provided the checksum is correct, the data
will be downloaded from the RAM. If the test fails, testing continues in the sequence indi-
cated above. If the data on the EEPROM are also defective, the fac
tory default data are loaded. In the event of repeated start-up/shutdown (more than twice
within 20 seconds) the error screen will appear, see above.
4.3 Battery management
Battery connection
After disconnecting and reconnecting the battery the instrument has to be started up wit-
hout a power input until the battery is depleted. Otherwise, the battery is considered deple-
ted and, depending on the actual charge, strongly overcharged.
Battery replacement
When the operating time of the instrument with a full battery is only less than 1.5 hours it
has to be replaced. The charging time to 80% capacity is approx. 3.2 hours, to 100%
approx. 12 hours.
Battery test for version V2.1 and higher
Discharge battery (switch on instrument without power line) until the audible alarm signal
sounds and the flashing message “Battery” appears. When this event occurs the battery
display reading is saved and after the plugging in of the power line can be seen in the
service screen. If the value is greater than 40 %, for instruments which have not been in
use for a long period, the battery can be formed by charging and depleting the battery
again. Otherwise, the battery has exceeded its service life and must be replaced.
When starting up the instrument after disconnecting the battery from the PCB ECG Moni-
tor it must be operated without power input until the battery is depleted. Otherwise, depen-
ding on the actual battery charge, battery overcharging may occur.
* A new battery should be depleted and charged 3 times to achieve full capacity.
* To maintain the battery capacity for a long time the battery should be depleted and
charged at least once a month.
