Once the correct password is entered, the PROGRAM mode will be entered and the first
parameter will be displayed, which is Parameter 0 - LINE VOLTS as illustrated below:

To scroll through the parameters, use the p and q keys on the keypad. When the
desired parameter is found, press the ENTER key to shift the cursor from the parameter
name to the parameter value. In this example, the cursor shifts from LINE VOLTS to
AUTO:

The parameter value can then be changed using the p and q keys. If the parameter
has a numerical value, the p key will increase the value and the q key will decrease
the value. If the parameter has specific choices that can be selected, the p and q
keys will scroll through the list of possible settings. When the desired value or option
is selected, press the ENTER key to store the new setting. If the new setting is not
ENTERED, it will not take effect and the old setting will still be valid.
If the PROG/RUN key is pushed while the cursor is highlighting the parameter value, the
value will change back to the original setting (if it had been changed, but not ENTERED),
and the cursor will shift back to the parameter name. Pressing PROG/RUN again will
exit the PROGRAM mode. If the PROGRAM mode is entered again within two minutes,
the last parameter that was viewed, or changed, will come up on the display. After two
minutes has elapsed, the password will have to be entered again when attempting to
access the PROGRAM mode.
