Battery-Backed RAM Status
Whenever you turn off a 250 Series Monitor, a battery provides power to the RAM
(random access memory) that stores information such as time, date, default settings,
etc.
Low Battery Icon
The icon shown above will appear in the upper right-hand section of the monitor
under the following circumstances.
NOTE: It is very important to set the time and date prior to initial operation of the
monitor and during daylight-saving time changes. A long-lasting battery
maintains the settings even when the monitor is unplugged from AC
power. Information on setting the time and date is found in the General
Setup screen section in Chapter 4 of the Corometrics 250 Series Monitor
Operator’s Manual.
