Yes, there is currently no vibrate functionality to the pod.
You are correct in thinking that there is somewhat of a predictability to the alarms (although as many others would probably agree, this is not always the case). Just like an occlusion alarm w/ a MM system which could alert “out of nowhere”, occasionally there are tell-tale signs such as pain at the insertion site during bolus delivery, blood in the canula, the past success rates of that particular site location w/ regard to alarms, etc, which are all helpful clues that an alarm might be more likely than at other times.
Most of my errors have come during pod filling or initial pod placements. There is an alarm that is set to “warn” you when then pod is approaching its expiration point, but it can be adjusted from both a “units left” and “time left” approach. So, for example if your pod were going to expire in 3 hours, and you were set to walk on stage for a 2 hour performance, you would not want to have your alarm set to notify you have an expiration between the 1 hour (that’s the minimum) and 3 hour mark, as this would alarm while on stage. You could adjust it on the fly at that point to alarm at a 4 hour (or more) mark, and as soon as this is set it should likely engage the alarm. You would then silence/acknowledge it, and you’d be good to go (it would not beep at you again until the expiration point that is 3 hours away). That’s a little wordy but hopefully that makes sense. The point is that if you are proactive about it, you can manipulate the settings so that they do not interfere with certain aspects of your job/life/etc.
