So I added my wife to my account as a user. You do have to fill out the entire user sheet, if you don't and try and save it the page flags red "this field required" text all over. Once saved the sheet said that password reset instructions have been sent to email address. Wife did get the email.
I have all this stuff figured out as well as instructions and quick tips sheets typed up for my work units with pictures and everything. To bad there are some differences between the personal account and corporate enterprise accounts. If they worked the same I would share.
I'll throw this warning out there. Make sure the SOS slider lock button on the SE is slid all the way to the right, the slider should click. You can make sure it's all the way locked by pressing the SOS button, if the button is solid the lock is engaged, if the button pushes in your lock slider is not engaged. It takes a 5 second press on the SOS button to activate the SOS feature so don't be afraid to do a quick press. Why is this important you may ask, well even with the unit off a 5 second press on the SOS button turns the unit on and puts it in SOS mode. If the unit is in your pack or the volume is turned off you won't know the unit is sending an SOS until the search and rescue team finds you.
