Low Battery Conditions
Low Battery Warning Icon
A low battery condition will be indicated on the front panel display by a
low-battery icon. This is not a “fuel gauge,” i.e., it means that the battery
level has dropped below a set point and should be changed.
Low battery icon
If attempting to activate sensors during a low battery condition, the
following cautionary statement may appear. An attempt to activate sensors
during this condition may result in the monitor shutting down.
Monitor shutdown precaution
Be aware of the following conditions when in a low-battery or no-
battery state. Tracking may be lost as well as the Real Time Clock.
• The non-volatile memory will retain sensor data indefinitely.
• If the monitor is off (with or without the battery) for more than one
hour, the monitor may not be able to resynchronize with the sensors.
• The longer the battery is missing, the greater the risk of the monitor
Real Time Clock losing the correct time. If the RTC time is lost, the
sensor tracking is lost.
