Setup and Programming

Programming and viewing of the various setup and
operating parameters is accomplished using the front panel
back lit, two line, sixteen character wide LCD along with
the 4 arrow buttons and the ENTER button. The name of
the parameter is on the top line of the display and the
setting value is on the bottom line.
To observe a certain parameter setting without intending to
change its value, just use the left and right arrow buttons to
navigate through the menus shown in the list. The current
setting for each parameter is shown on the bottom line of
the display. Note that depending upon certain settings,
some screens are not needed and will be skipped.
To make a change in the displayed parameter and its
setting and if this is the initial setup, you will want to enter
the 'adjust' mode. To do this, press the ENTER button that
is located in the center of the four arrow buttons and hold
in for several seconds until the display begins to flash.
After you are in the adjust mode (bottom line of screen
flashing) use the left and right arrows to navigate among
screens and use the up and down arrows to change the
parameter setting. When ENTER is pressed, the new
settings will be loaded and stored and the unit will exit the
'adjust' mode. You may wish to not press ENTER until you
have gone through all screens and settings and then
press ENTER to save and load all changes in one step
OR you can store just one or several parameters at a time
and reenter adjust mode to set the next. Either method is
acceptable.
