12 Understanding PDM and Pod Function
When you are not actively using the PDM, store it in a nearby location,
such as a shirt pocket or in a drawer, briefcase or handbag.
Status checks: How the PDM checks Pod function
The PDM periodically queries the Pod about its status, called a “status check”.
The PDM performs a status check:
• When you wake up the PDM.
• When you navigate to the Pod Info tab.
• Periodically, whether the PDM is awake or asleep. These “sleeping status
checks” occur every five minutes.
Note:
Following a sleeping status check, the PDM only wakes up and sounds
an audible alarm if the Pod has a hazard alarm. If the Pod has an advisory alarm
or a notification, the PDM remains asleep and silent.
During a status check, the PDM collects information from the Pod about bolus
deliveries, the amount of remaining insulin and any alarm situations. The PDM
displays this information as follows:
• The Home screen displays information about the most recent bolus.
• The Pod icon on the status bar shows how much insulin remains in the Pod’s
reservoir (see “The Status Bar” on page 9).
• The Lock screen and a full screen message display information about Pod
alarms.
Timing of alarms originating in the Pod
If the Pod is sounding a hazard alarm, the Pod broadcasts a signal to the PDM.
• If the PDM is in range and awake, within 25 seconds of the Pod’s initial alarm
sound, the PDM also sounds an alarm and displays the alarm message.
• If the PDM is in range but asleep, the Pod cannot wake it up. The PDM finds
out about the Pod alarm when it does a “sleeping status check”.In this case,
there could be a delay of up to five minutes and 25 seconds between when the
Pod sounds the alarm and when the PDM sounds the alarm.
• If the PDM is out of range of the Pod, the PDM cannot receive any
communication from the Pod. Therefore, if you hear a Pod alarm or
notification, bring the PDM in range of the Pod and wake the PDM up.
Within 25 seconds, the PDM sounds the alarm and displays the alarm
message.
When the PDM cannot communicate with the Pod
When the PDM attempts to communicate with an active Pod that is in range,
communication usually occurs quickly.
