We just started on the Dexcom and I'm surprised it isn't louder. We have to be pretty close to it to hear it. Maybe we just have a noisy house (3 kids, small house), but we just aren't hearing it even if it's within range of the transmitter. We do use a baby monitor at night to amplify the alarm, and I suppose we could do that during the day. Just wanted to make sure - Attentive is the loudest profile? And there isn't a way to directly change the volume (other than changing the profiles)? Is there something obvious I'm missing? Like some iPhone users complained of low volume until they realized they were forgetting to remove the plastic from the speaker.
