System-Level Commands

Several system-level commands are available to the user. These commands can
be entered via Screen 4, SUBCMDS menu, or from Screen 8. Table 2.2 lists the
commands.
To use these commands, start by pressing the [e] key for data-entry mode. Then
use the number keys to enter the desired command. Press the [e] key again for
the command to be accepted. Pressing [c] instead of the final [e], cancels the
command and the unit returns to display mode.
