CAUTION
NETWORK DEVICE TIME SYNCHRONIZATION — When
adding a new device (e.g., CIC Pro center) to the CARESCAPE
Network, the existing devices on the CARESCAPE Network will
synchronize to the new device’s time. To prevent potential time
synchronization issues, you should set the new device’s time to be as
close as possible to the time (within a few seconds) used by the
existing GE devices on the CARESCAPE Network.
