I’m swapping out a Zen34 for a Zen37 and will put the Zen34 on the shelf until I have another use for it.
Is there a way to power it off? What’s the best way to handle this?
The Zen34 doesn’t have batteries I can take out like the 37
The ZEN34 model is powered by 2 coin cell batteries so you can simply take them out of the device to power it off 
Sorry I misspoke there, got my numbers mixed up
the Zen37 doesn’t have batteries like the Zen34, so there’s nothing to remove.

No worries! Since the ZEN37 battery is not removable, simply let the battery drain and recharge when needed.
