Replacing the System Battery
The system’s lithium battery, located inside the system electronics, maintains con-
figuration settings at all times, even when the system is off.
The memory backup life of the battery is approximately 3 years if left unplugged.
When the system is plugged in, the standby current from the power supply
extends the life of the battery. The battery rating is CR2032 3-V Single Cell,
225 mAh.
If, however, the system battery loses its charge, the system defaults to the stan-
dard configuration settings, and the system clock may fail to show the correct
time. However, there are no patient safety concerns. To replace the battery, con-
tact your Philips service representative.
WARNING
There is a danger of explosion if the battery is replaced incorrectly. The battery
should be replaced only with the same or equivalent type recommended by the
equipment manufacturer. Used batteries must be discarded according to the man-
ufacturers’ instructions and local ordinances.
Disposing of Equipment
Dispose of the ultrasound system according to local ordinances. Dispose of
peripheral equipment in accordance with manufacturers’ instructions and local
ordinances.
