Why would I need to change my USER ID?
The User ID is a unique identifier used by the Handheld Device and shared with the GPS Collar with E-collar Module. The Handheld Device uses an ID value to distinguish it from other Handheld Devices. This ID is factory set and for most users will never need attention. The ID value can be viewed on either the STATUS or ABOUT screens. If the factory-set User ID on your Handheld Device conflicts with another Handheld Device or similar device, you should change the User ID to eliminate the conflict. Alternately, if two users want to have the ability to monitor the same dog(s) with each user operating his own Handheld Device, they can choose to set their User IDs to match.
