SECTION 3 PRINCIPLES OF OPERATION
_______________________________________________________________________

3.3.4 BISx Data Memory

The BISx stores processed EEG parameters, including the BIS value, with time and date of
acquisition. History data stored in the BISx can be accessed by exporting it to a removable
drive using the [Export Data] function. The duration of BISx data stored is approximately
1200 hours.
To view BISx history for a specific case, the user must first identify which BISx was in use
during the case by looking up the BISx serial number in the Advanced Diagnostics menu's
[BISx Connection History]. The appropriate serial number BISx can then be connected to
any monitor to export its History Data.
When the BISx memory is full, the oldest data are automatically erased as new data are
stored. Memory will be retained even if the monitor battery has been discharged and remains
when the monitor and BISx are powered off.

3.3.5 Saved Settings

Whenever the monitor is started up from Standby mode, it reverts to user settings that have
been set up and then saved using the [SAVE ACTIVE] selection from the Settings menu.
Note:
The [SAVE ACTIVE] option is disabled when in Battery Backup-Low Power condition.
The following settings are not saved by the [SAVE ACTIVE] option: Impedance Checking
(always returns to ON), Diagnostics Codes (returns to OFF).
To restore factory settings, go to MENU/Maintenance/Default Settings and press
[Restore].

3.3.6 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 next to 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 Power Low" message blinks
continuously in the Message area of the screen.
The Save Settings feature is disabled when the battery power is low. Battery recharge time is
approximately 6 hours.
Caution:
To turn off all A/C power, disconnect power cord from A/C outlet.
Battery can be removed to shut down unit completely.
