Resetting to Factory Default Values
All user options (
) can be set to the factory default values using the MODE and SEL buttons.
To set the user options to their default values:
1
Press the SEL button for 6 seconds until the following message appears:
DFLT NO
2
Press the SEL button while the
DFLT NO
message is displayed.
The message changes to
DFLT YES
indicating the factory default values are now in effect and the display
returns to the normal mode.
To terminate the DFLT mode without setting the factory default values, do one of the following:

Press the MODE button to return to the normal display mode
•
Wait 30 seconds for the unit to return to the normal display mode.
Displaying System Parameter Settings
To scroll through the current settings of all system parameters, press the MODE button for 3 or more seconds. The
following parameters are displayed:
•
HLU software version number
•
HLU List number
•
Type of frame pattern being received from the DSX-1

Disabling an Alarm
If the system is in a Minor alarm state, the alarm relay can be disengaged by pressing the SEL button. This turns
off the Alarm Cut-off (ACO) indication.
Loopback Modes
“Loopback Operation” on page 42
for instructions on using the MODE and SEL buttons to activate loopbacks.
The line code parameter is the actual DSX-1 line code being received by the HLU if the DSX-1
code pattern is set to AUTO. Otherwise, the line code parameter mimics either of the other two
line code settings, Alternate Mark Inversion (AMI) or Bipolar with 8-Zero Substitution (B8ZS).
