34 TSU 600 User Manual 61200.076L2-1
Set User Passcode
The TSU 600 is designed to operate with or without
the use of a password.
The passcode should be a number easily remembered. Once
entered, the passcode is required to access any operation
other than viewing.
To Establish a Passcode
Select SET PASSCODE (item 3) under the UTIL menu.
At the New Passcode prompt, use numbers from the
front panel of the keyboard to enter a unique number
up to four (4) digits.
After pressing Enter a verification prompt is dis-
played. Respond to the verification prompt by
repeating the same passcode number.
If the two entries match, the unit accepts the passcode.
If they do not match the unit returns to the new
passcode entry field for another attempt.
If the unit is to be remotely accessed using T-Watch, a
passcode must be entered. When managing a number of
units, the passcode can be the same for all.
Special Feature
For added security protection the unit is equipped
with an automatic time out for operation with the
password. After ten minutes of inactivity, the unit
reverts to limited access operation. To make changes
in the configuration, the passcode can be reentered.
See Passcode in the chapter Operation for further
information concerning passcode use, and both
limited and editing access.
If the passcode number is lost, contact ADTRAN Customer
Service for assistance.
