Using the Battery
The battery powers the monitor when the monitor is not con-
nected to line power via the AC adapter, an IDS Docking Station,
or a CPS Communication Power Supply (IDS and CPS are
described in the chapter Network Applications). The battery fits
into the battery compartment at the back of the monitor.
There are two types of batteries: lead acid, or lithium ion (shown
below). Lead acid batteries provide 75 minutes of continuous
monitoring; lithium ion batteries provide 180 minutes of continu-
ous monitoring.
Lead acid batteries can be installed or removed by the user. Lith-
ium ion batteries must be installed or removed by Dräger
personnel. The green battery gauge displayed at the bottom left
of the screen indicates the battery run time remaining for uninter-
rupted monitoring.
NOTE: The battery gauge appears only when you operate the
monitor on battery power.
When the battery charge is less than approximately 25%, the fol-
lowing happens:
! The battery gauge displays in yellow.
! The monitor emits an alert tone.
! The monitor displays the message Replace Battery Pack at
frequent intervals.
