Data Memory
The monitor stores recorded trend data with time and date of acquisition. The duration of
trend data stored is approximately 72 hours.
When the memory is full, the oldest data are automatically erased as new data are stored.
Memory will be retained even if the battery has been discharged and remains when the
monitor is in the power off condition.
3.9.4
Battery Operation
In the event of a power failure or interruption of power during a procedure, the monitor
automatically switches to back-up battery operation. A fully charged battery will provide
approximately 45 minutes of operation. When the system is running on battery, a battery
icon displays above the BIS number, indicating the battery status. When the battery reaches a
low power condition, the monitor beeps and the battery symbol displayed on the screen
changes color from green to orange. In addition, a “Battery Voltage Low” message blinks
continuously in the Message area of the screen.
Battery recharge time is approximately 6 hours. The battery charges continually as long as
the unit is plugged into A/C power.
Caution:
To completely remove power from the unit: put the monitor in Standby
mode, disconnect power cord from the power cord receptacle of the
monitor, then remove the battery from the monitor.
