Wireless: How can I identify a MK I versus MK II Beltpack?
Mk II beltpack can be identified by powering on a beltpack and while in search mode you tap the right hand menu key, it will take you into an information screen, the top line will alternate every 10 -20 seconds if one of the top lines starts with 3K then it is a MK II beltpack, but if it starts with 1K or 2K it is a Mk I beltpack.
