The following battery-related INOP messages are issued by the Monitor. All INOPs continue
until the Monitor is plugged into the AC power or the INOP condition is fixed.
BATTERY LOW—This is a hard INOP which indicates that the remaining battery-operating
time is less than approximately 20 minutes.
REPLACE BATTERY—This is a hard INOP which indicates that the UHVWLQJVWDWH operating
time for the Monitor is guaranteed for a further 5 min only (this information is derived from
the voltage of the battery). The battery LED blinks at a rate of 1.5 red flashes per second. A
severe INOP switches the main alarms-suspended status back to on, and generates an INOP
alarm. If this alarm is silenced, it recurs after 3 minutes.
The previous two INOPs are cleared if AC power is connected, while the following INOP
stays no matter whether AC power is connected.
BATTERY MALFUNCTION—This is a severe INOP which indicates a malfunction of the
hardware or the battery. A severe INOP switches the main alarms-suspended status back to
on, and generates an INOP alarm. If this alarm is silenced, it recurs after 3 minutes. 1RWH: if
this INOP occurs after initialization, it may indicate the the battery cannot yet communicate.
In this case the message will disappear in 5 to 10 minutes.
