How do I initialize the tracker to factory defaults?
Send an SMS with the command “begin+password” (e.g., “begin123456”) to the unit, and it will reply “begin ok”, resetting all settings to default values. If a new password is needed after initialization, perform a change password operation following specific instructions in the manual.
