• Operational Hours – The operational hours displays
the total number of hours that the device blower has
been on since the last time this value was reset. You can
reset this value to zero (0) if desired (e.g., each time you
give the device to a new patient). This value helps you
determine how often the patient is using the device. The
Operational Hours shown here diers from the Blower
Hours shown on the Information screens. The Blower
Hours displayed in the Information screen is the total
number of hours that the blower has been working over
the life of the device. You cannot reset this value.
Viewing the Alarm Log
From the Main Menu screen, you can select Alarm Log to access the
Alarm Log screen. An example is shown below.
The alarm log displays the alarms in chronological order with the
most recent events displayed rst. It lists the 20 most recent alarms
or messages that appeared on the device display. When the device is
in Limited Menu access mode, the alarm log cannot be cleared. It can
be cleared when in Full Menu access mode. Depending on how many
alarms have occurred, the alarm log may be several pages long. The
entries in the alarm log use the same names that displayed when the
alarm initially occurred and was displayed in the Alarm View.
Note: In the Alarm Log screen,
the 1/2 shown in the Menu
banner indicates that page 1
of 2 alarm log pages is being
viewed at this time.
