battery.
• Admin Login — Used to log into the homepage as Administrator. You must be

mobile hotspot settings. The default Admin Login is printed on a label under the
battery. The Admin Login can be 5–31 characters.
• Guest Wi-Fi Password — When enabled, guests can use this password to access the
Guest Wi-Fi network.
