   Amateur radio operators are required to identify all transmitting stations. The AREDN |trade| node name is beaconed automatically by the node every five minutes, so the node name must contain your callsign. Recommended names follow the (callsign)-(label) format, such as AD5BC-MOBILE or AD5BC-120SE. As a general rule node names should be kept as short as possible, while clearly and uniquely identifying the node.
 
 Password
-  Set a new administration password for the node. Enter it again in the *Retype Password* box to verify it is correct. You can click the *eye* icon at the right of the password fields to toggle between hidden and visible text. The first time a node is configured it will require you to change the password. Be sure to remember or record the new password so you can use it for any future administrative tasks on the node.

 Node Description
   This is not a required field, but it is a good place to describe the features or function of this device. Many operators use this field to list their contact information, the radio model and antenna specifications, or the tactical purpose for the node. There are no character restrictions in the field, but the maximum length allowed is 210 characters.
