SET PASSCODE

The TSU LT uses passcodes for front panel security and T-Watch PRO access. Use S

ASSCODE

to add,

change, or delete a passcode. Acceptable codes are 0000 through 9999. Four question marks (

????)

indicate the keypad is locked.

To alter the passcode, highlight

ASSCODE

and press E

NTER

. Then use the U

and D

OWN

arrow keys to

change the digits. After changing a digit, press

NTER

to move to the next digit. To skip a digit, press

NTER

while the cursor is blinking on that digit.

KEYPAD

Allows the user to lock or unlock the front panel keypad. This feature keeps the unit configuration from

being changed by unauthorized personnel. When the keypad is L

OCKED, option settings can be viewed but

not changed (unless the passcode is entered). When the keypad is U

NLOCKED

, the menus can be changed

at will. If an incorrect passcode is entered, the unit remains locked.

FACT RESTORE

Use the F

ACTORY

ESTORE

submenu to restore the factory default setting for all unit parameters.
