Power Up Testing
When shipped from the factory, the TSU 120 is set to factory
default conditions. At the first application of power, the unit
automatically executes a memory self-test. A full self-test can
be run from the front panel. A passcode and Unit ID may be
set using the

Initialization
Set User Passcode
The TSU 120 is designed to operate with or without the use of a
passcode. The default condition is without a passcode.
If the unit is to be remotely accessed using T-WATCH Pro, you
must enter a passcode. When managing a number of units, the
passcode can be the same for all the units.
The passcode should be a number easily remembered. Once
entered, the passcode is required to access any operation other
than viewing. See Change/Set a Passcode on page 6-4 for details.
Set Unit Identification
The Unit ID sets the unit to respond to remote control (con-
trolled by a device other than the front panel or terminal). If no
Unit ID is recorded it is not possible to operate from any remote
control device, including the local PC for T-WATCH Pro or
SNMP. See Unit ID on page 6-4 for details.
