Beltpack setup and pairing
When you operate each Beltpack for the first time with the Mobile Station, you must pair up the Beltpack with a
Mobile Station. This pairing process allows a Mobile Station and a Beltpack to recognize each other and an own
cryptic code will be given for the corresponding system. The Mobile Station will identify all the paired up
Beltpacks and recognize the difference between the Beltpacks. If a Beltpack is added or replaced later, the new
one is necessarily to be paired up with the Mobile Station.
Each Mobile Station allows up to one hundred twenty eight(128) Beltpack connections.
Beltpack setup
Before pairing up the Beltpack with the Mobile Station, set up all Beltpacks as following steps:
Slide the cover down to open the battery cover (#10), and put a fully charged rechargeable battery pack (BAT50
