Philips IntelliVue X2 Instructions For Use Manual page 234

21 Using Batteries
Note that your monitor may be configured to dim or brighten the display brightness automatically
when you disconnect from power, to suit the most common transport scenario
("TransportBrightn" setting).
Charging a Battery
A battery can be charged in a monitor during monitoring. You can also use the M8043A Smart Battery
Charger to charge batteries.
Insert the battery into an X2 connected to a host monitor or the external power supply (M8023A)
1
that is connected to mains power.
Charge the battery until it is full, the battery LED goes out, and the battery power gauge is filled.
2
In certain situations, internal temperature conditions may mean that the battery will not charge. This is
sometimes necessary to protect the battery from damage, and does not indicate a malfunction. In this
case you must use the M8043A Smart Battery Charger to charge the battery.
Conditioning a Battery
You must condition a battery when its "battery requires maintenance" symbol shows on the Screen. Do
not interrupt the charge or discharge cycle during conditioning.
CAUTION Do not use a monitor being used to monitor patients to condition batteries. The monitor switches off
automatically when there is no battery power left.
You can also use the M8043A Smart Battery Charger for external battery conditioning (requires
adapter, order number 4512 610 17451). For details please see the Instructions for Use for the Smart
Battery Charger. Do not use any other battery chargers or conditioners.
To condition a battery using a monitor,
Insert the battery into an X2 connected to a host monitor or the external power supply (M8023A)
1
that is connected to mains power.
Charge the battery until it is completely full. Open the Battery Status window and check
2
that the Batt Fully Charged message is displayed.
Disconnect the X2 from the external power supply (M8023A) or host monitor, and let it run until
3
there is no battery power left and the X2 switches itself off.
Reconnect the monitor to mains power or a host monitor and charge the battery until it is full for
4
use or charge to 50% for storage.
Storing a Battery
A battery should not remain inside the monitor if it is not used for a longer period of time. Batteries
should be charged to a maximum of 50% for storage.
N O T E The battery will discharge over time if it is stored inside the X2 when not connected to a powered
(either running or in Standby) host monitor or the external power supply (M8023A). The reported
values for "remaining capacity" and "runtime" will become less accurate when the battery is stored in
this way for a longer period of time (that is, several weeks).
